Meet the Latest Sparkfuns MicroMod Function and Carrier Boards

SparkFun recently added a host of new MicroMod boards and Carriers to its fast-growing MicroMod family. The new boards include a MicroMod ESP32 Function Board, a MicroMod DA16200 Function Board, a MicroMod LoRa Function Board, a MicroMod Environmental Function Board, and a Single/Double MicroMod Main Board.

The SparkFun MicroMod DA16200 Function Board debuts additional onboard IEE802.11b/g/n WiFi module featuring a 40MHz crystal oscillator, RF filter, 4MB Flash, 32.768KHz RTC, a Chip antenna, and JTAG connectors for programming and debugging for upgrading any MicroMod solution. With a low current draw of 0.2uA – 3.5uA in sleep mode, the SparkFun MicroMod DA16200 Function Board is suitable for the development of automation projects requiring door locks, sensors, thermostats, and IoT solutions.

The second board, the SparkFun MicroMod WiFi Function Board – ESP32 is designed to serve as a coprocessor board, utilizing ESPRESSIF’s ESP32 WROOM (ESP32-DOWD-V3 Chip) to add WiFi and Bluetooth wireless features to original MicroMod processor boards without such features. The onboard ESP32 WROOM is equipped with 16MB Flash, 520KB SRAM, a dual-mode Bluetooth, an IEE802.11b/g/n WiFi transceiver, and an M.2 MicroMod interface to aid connection without inter-board soldering. The board also features a UART port that can be used to control the ESP32 WROOM module via AT commands, USB-C connector, and CP2102 USB-to-Serial converter.

The next Board, SparkFun MicroMod LoRa Function Board, is expected to be used alongside a MicroMod processor board on a Main Board (Host) that offers LoRA and LoRaWAN network capabilities for any MicroMod development. The Main Board is designed to host the duo attachments and provide an electrical connection between them. The LoRa Function Board features Ebyte’s LoRa 915M30S module, a 30dBm transceiver utilizing Semtech SX1276 Communication protocol. It has an edge mount RP-SMA connector suitable for 915MHz LoRa antennas, and a U.FL interface.

The last function board, the SparkFun MicroMod Environmental Function Board provides sensing capabilities to MicroMod processor boards with an SGP40 sensor for air quality sensing, an SHTC3 sensor for temperature and humidity sensing, and an STC31 sensor for sensing CO2 concentrations in your room. This Board features an I²C port, an AP2112 3.3V voltage regulator, and jumpers for selectively addressing the STC31.

Talking about the Main Boards, the MicroMod Main Boards are special Carrier boards designed to carry a MicroMod processor board and a single or double MicroMod Function board, providing the electrical connection between them. Both boards feature a 2A fuse, 3.3V/1A voltage regulator, and a USB-C interface for power and programming of the processor board. While the Single Main Board allows interfacing a MicroMod processor board with one Function board, the Double Main Board allows interfacing with two Function boards.

There are tutorial links for all the new boards on each Board sales page. You will see links to each product’s page below.

The new MicroMod boards are available for purchase on SparkFun shop at $14.95 for the WiFi Function Board – ESP32; $29.95 for the WiFi Function Board – DA16200; $39.95 for the LoRa Function Board; $149.95 for the Environmental Function Board; $14.95 for the Single Main Board; and $17.95 for the Double Main Board.
