RealTek RTL8126 5Gbps Ethernet Card Costs $12 and more

Posted on 15 July, 202415 July, 2024 by Debashis Das

The Realtek RTL8126 is a 5Gbps Ethernet controller IC designed for high-speed networking applications. It’s designed to be a low-power, cost-effective product that brings 5Gbps Ethernet connectivity to devices like desktops, laptops, and servers. The IC was first unveiled at Computex 2023 last year and at the time of writing, there are some M.2 modules and PCIe cards available at competitive prices.

There is not much information available about the specific product but, you can purchase it from Amazon for around $12. The module is a 5000Mbps Networking Card B+M Key to a PCIe Adapter. The module is an M.2 PCIe card with a ribbon cable coming out, and with the cable, the RJ45 jack is attached to a PCIe bracket. The card was added recently and there is not much information about it.

It’s very common knowledge that the 10GbE ICs get very hot without adequate cooling but the RealTek RTL8126 chip used here tops at about 82°C under heavy load. There are also divers available for the board and on Windows 11 the drivers are installed automatically. But if you are in Linux you need to install the drivers manually. The drivers are provided by RealTek for this chip, and it will not work seamlessly the new 5GbE controller has not made it to most Linux distributions.

RealTek RTL8126 5Gbps Ethernet Card Specifications

Interface: PCIe 3.0 x1
Speed: 5 Gbps
Compatibility: Cat5e and Cat6 cables
Form Factors:
- M.2 PCIe module with PCIe bracket adapter
- PCIe x1 card
Drivers:
- Windows: Automatic installation
- Linux: Requires manual driver installation (available from Realtek)
Price:
- M.2 module: Starting at $12
- PCIe card: Starting at $12

While choice is limited now, expect a surge in RTL8126 PCIe cards and M.2 modules due to their affordability. The RTL8126 is likely to replace the RTL8125 in upcoming mini PCs. For a 5GbE USB dongle, we’ll need to wait for the RTL8157 controller. Finding a dedicated 5GbE switch might be tricky, as current searches often yield 2.5GbE options. For now, a 10GbE switch might be the best bet.

An Arduino Nano Clone in a DIP-Sized Footprint

Posted on 15 July, 202417 July, 2024 by Aditi Ambadkar

The Arduino Nano and its many clones are staples in the world of development boards, often found within arm’s reach of any electronics enthusiast. However, even the compact Nano can take up valuable space on solderless breadboards during prototyping. To address this, [Albert van Dalen] has created a miniaturized version of the Nano called the “Nano DIP.” Measuring just 33 mm x 10 mm, the Nano DIP is about the same size as the ATmega328 on the Arduino Uno, making it a delight for those who appreciate miniaturization.

Arduino Nano DIP features:

DIP26 size, 33 x 10 mm
Arduino Uno compatible
ATtiny3217 instead of the ATmega328P
21 I/O pins
12 x 10 bit ADC channels
Supply voltage 1.8V – 5.5V
Supply voltage V+ max18V
Clock 16MHz (for compatibility reasons, the max frequency is 20MHz)
Straightforward pinout

Additional features compared to the Arduino Uno

1 x fast 350ksps 8-bit real DAC
The USB supply pin is protected by an ideal diode that doesn’t have a 0.7V voltage drop
A 2-pole header, which is connected to D2, can be used as a jumper. Use pinMode(INPUT_PULLUP)
The LED at D0 can be disabled by a jumper

The Nano DIP is built around an ATtiny3217 microcontroller and retains nearly all the features of the original Nano. It includes a USB port, a reset button, built-in LEDs, a 5V regulator, and a preloaded bootloader. The 350-kilosamples-per-second 8-bit DAC is a standout feature, although it comes at the cost of losing external crystal pins and a 3.3V regulator.

To make the board affordable to manufacture, [Albert] opted for a minimum component size of 0402, presenting a significant design challenge. The microcontroller barely fits between the header pin pads, and the Micro USB jack had to be a vertical-mount type. Despite these constraints, the Nano DIP performs admirably, offering the same functionality as a standard Nano in a much smaller footprint. If you are looking to free up space on your breadboard without sacrificing functionality, the Nano DIP is an excellent option to consider.
