Pine64 Unveils Quartz64 model A SBC for Developers and Linux Users Along with SOQuartz Module

Posted on 20 July, 2021 by Saumitra Jagdale

Recently, we have seen the launch of the Firefly ROC-RK3566-PC mini-computer built around the Rockchip RK3566 chip. To continue the emergence of RK3566-powered development boards, the Quartz64, a single-board computer (SBC) has been released by Pine64. With the integrated powerful processor, the SBC provides access to a wide range of features.

Pine64 has also unveiled the SOQuartz, a new product in the Quartz series. It is a system-on-module based on the NPU-equipped RK3566 that features industry-standard 100-pin high-density connections to resemble the Raspberry Pi Compute Module 4.

The company recommends Quartz64 for developers and expert Linux users who want to contribute to early software development. Additionally, both mainline Linux and Rockchip’s BSP version of Linux have been booted on the platform. Also, the development process is moving rapidly, but it will be months before end-users and industry partners can safely deploy it.

Technical Specifications of Quartz64 Model A

The manufacturer planned to split the Quartz64 SBC line in two, similar to the Raspberry Pi family, with a Model A and a Model B. The 133 x 80 x 19mm Quartz64 model-A harnesses the capabilities of Rockchip RK3566. The RK3566 features a quad-core Cortex-A55 processor clocked up to 1.8 GHz frequency. It also comes with a Mali-G52 2EE Bifrost GPU running at 800MHz, and an integrated neural processing unit (NPU) coprocessor that delivers 0.8 TOPS of performance.

The developer-focused model-A is compatible with LPDDR4 memory options ranging from 2GB to 8GB, depending on the user’s needs. It will also support a Gigabit Ethernet port along with optional wireless connectivity of Wi-Fi 802.11 b/g/n/ac and Bluetooth 5.0. In addition to the MIPI-DSI, eDP, and E-ink interfaces, the SBC supports an option for 16GB to 128GB eMMC modules. It also comes with a microSD card for removable storage.

Talking about the Quartz64 model-B, it is expected to be released in the coming months. According to Pine64, the Model-B will have either a BL-602 RISC-V 802.11n and BLE 5.0 module, which is currently open-sourcing, or an AP6256 802.11ac WiFi + Bluetooth 5.0 module. The compact size makes this device a great choice for education, tinkering, personal projects, and similar applications.

The main difference between the two models is in their connectivity. The Quartz64 Model B lacks the Model A’s SATA port, embedded DisplayPort (eDP) interfaces. Along with this, the MIPI-DSI and -CSI interfaces are two-lane rather than four-lane. The Model B also removes the touch-panel controller and charging circuit. On the other hand, Model B provides user-friendly features. These include onboard Wi-Fi and Bluetooth connectivity and a 40-pin GPIO header rather than the 20-pin header on the Model A. Additionally, Model B has an M.2 slot instead of a PCIe interface.

A developer can build many exciting projects with the Quartz64 SBC. Nevertheless, Pine64 plans to leverage the Quartz64 model-A as a development platform for its next-generation smartphones, laptops, and other devices. Model-B is still under development, while model-A has begun selling to community members.

SOQuartz

The firm also unveiled the SOQuartz module. It is a compute module that may be a drop-in replacement for the Raspberry Pi Compute Module 4. Thus, it has a pair of 100-pin high-density connectors allowing you to connect the module to various carrier boards. SOQuartz will feature the RK3566 SoC, the Azurewave AW-CM256SM WiFi802.11ac Bluetooth and WiFi module with a U.FL antenna connector, and the same software as the Quartz64 boards.

“Flash storage can be added via the eMMC socket (it accepts standard PINE64 eMMC modules) or by having it soldered on the back-side of the PCB. The option for a soldered-on eMMC adds a degree of flexibility for industry partners who may wish to standardize a hardware rollout.”, says Pine64.

The June blog post also provides information on an optional PinePhone keyboard and a PineDio LoRa gateway based on the Pine A64-LTS SBC. However, the Quartz64 Model A is available in two RAM capacities: a 4GB model for $59.99 and an 8GB model for $79.99, both of which are currently available for purchase on the company’s website.

R1810 Boost DC/DC Converter is an energy harvesting solution

Posted on 19 July, 202119 July, 2021 by mixos

The R1810 Boost DC/DC Converter is an energy harvesting solution designed for powering low current consuming IoT devices by extracting energy from Photovoltaic cells. Target applications include wireless sensors, home and building automation, remote monitoring, presence detection, industrial equipment controls and more.

Tailored specifically to replace the conventional batteries with power supplies operate with photovoltaic cells, the R1810 Boost DC/DC Converter starts up with only 9µW provided from a single cell photovoltaic element. The new IC with its ultra-low power consumption and high-efficiency features enable storing power from any type of 1 cell photovoltaic element. Its start-up voltage is only 0.5 V and once started, the operation continues even if the input voltage drops below 0.2 V. Moreover, it has a high-efficiency performance of 66% at 5 µA output current (Vin=0.5V, Vset=2.6V).

An internally fixed maximum power point voltage (VMP) and output voltage setting (VSET) of the device helps in optimizing the performance of the electrical circuit with respect to the selected energy harvester type. Upon the availability of sufficient energy on the input and increases above the VMP level, the boost DC/DC Converter can transfer energy from the input to the output. On the other hand, when the amount of transferred power exceeds the supplied power from the photovoltaic cell, the input voltage decreases below VMP and the DC/DC converter stops switching.

The converter comes with two monitoring circuits that indicate the status of the conversion process on the respective outputs. First Input Power Good function becomes active when the output voltage level falls below the VOUTUVLO voltage and whether the DC/DC converter stops switching for at least 1.5 seconds. Other Output Power Good function indicates that the output voltage level drops below 50 to 80% of its nominal level, this threshold is internally set and specified by the product version.

The built-in reverse current protection helps in preventing a current flow from output to input when the light on the photovoltaic cell is blocked. In the event of input voltage drop below the output voltage, the high side MOSFET transistor is turned off to avoid a reverse current draining the energy storage capacitor. The R1810 is available in a regular DFN2735-14 or a tiny WLCSP-15-P1 package. Samples and fully assembled + tested evaluation boards can be purchased from our authorized local distributors and online partners such as Mouser and Digi-Key.

VoltLog’s CanLite is an ESP32-based CAN Bus Development Board

Posted on 19 July, 2021 by Saumitra Jagdale

Yet another development board featuring Espressif Systems’ powerful ESP32 microcontroller. VoltLog recently released the CanLite, a wireless CAN bus hacking, and development board built around an ESP32 microcontroller.

But the CanLite was not meant to be a universal development board, because limited I/Os are available. However, it was designed as a development board tailored to meet the maker’s specific requirements. Yet, many users will find that the features selected by the maker are also suitable for their own projects. Additionally, the board is programmable using the Arduino IDE or ESP-IDF through the onboard JST-SH VoltLink pin header.

Espressif’s ESP32 microcontroller is at the core of this compact CAN Bus wireless board. It is one of the most popular microcontrollers because it is a complete standalone system. Along with this, the dual-core processor provides a lot of processing power as well as Wi-Fi and Bluetooth connectivity for remote control and over-the-air updates (OTA).

The board gets its power directly from the car’s +12V system via the built-in automotive-grade DC-DC step-down converter. On the input of the converter, there is additionally reverse polarity and over-current protection, which adds another layer of safety to the protective measures given by the dc-dc converter itself.

CanLite also features an optional two-channel high-side automotive-grade switch, ST’s VN750PS. It is capable of switching up to 6A per channel with integrated safety provisions. You can purchase the board with one, two, or no high side load switches assembled.
Furthermore, with the inclusion of a voltage regulator, the board can also measure VBAT voltage, allowing it to go into a deep sleep, for example, if the car battery voltage falls below a particular threshold.

Technical Specifications of CanLite ESP32 CAN Development Board

Espressif ESP32 processor working at a frequency of 240 MHz.
It comes with integrated 4MB of flash storage and also features 520kB of on-chip static RAM (SRAM)
Measurement of VBAT voltage uses an onboard voltage divider, and make code decisions based on that.
The ST VN750PS, a high-side driver in a SO-8 package, enables you to switch automotive accessories
Texas Instrument’s SN65HVD231 is a low power, high performance CAN interface transceiver
The onboard 120-ohm termination resistor is configurable via a solder jumper.

Since the ESP32 has the controller part but cannot drive the actual CAN signals or differential signals on a CAN bus, an external transceiver is necessary. Hence, the board employs an SN65HVD231 controller area network (CAN) transceiver, ensuring a robust and compliant interface is provided. It includes many protection features that ensure device and CAN network reliability. Also, the transceiver is compatible with ISO 11898-2 at data rates up to 1Mbps.

You can check out the GitHub repository for exploring the software support of the device. The CanLite ESP32 CAN Development Board is available on Tindie for $30.99. For information, you can visit the official product page on Tindie’s website. Technical specifications and images have also been taken from the product page.

Posted on 19 July, 2021 by Emmanuel Odunlade

There is absolutely no end to the number of different types of modules and devices in which the ESP family of WiFi modules/microcontrollers have been featured, thanks to their integrated nature and small form factor. While the ESP8266 and ESP32 variants are the most known, other less-known versions like the ESP8285 have recently been garnering popularity with several products based on it, including the recently released PSF-B 4-gang Wi-Fi Switch Module, by china-based home automation solution provider; ITEAD.

A 1-4 gang ultra-low-power Wi-Fi switch module, the ESP8285-based PSF-B Switch module was designed to enable rapid development of WiFi-based, home automation switch solutions. It comes with the ability to switch up to four independent household points/appliances and can be controlled via connected pushbuttons, or controlled remotely by connecting it to a privately developed, or publicly available app like ITEAD’s eWeLink.

Key Features:

Built-in 32bit MCU, and can double as an application processor
