Despite the differences in size and microcontroller, the Arduino Nano and Micro share some similar ... RC522 RFID module, and TFT display module. The I2C/TWI pins on the Micro are on D2 and ...
The circuit is extremely simple, comprising the sensor, an Arduino Nano, and an OLED display. This device is handy because its voltage output has a known relationship to the gauss level the sensor ...
If you're on the hunt for the perfect board, then you've probably come across the Uno and Nano. They're two of the most frequently used Arduino variations, but they serve different purposes.
Although a “CommsLink” module providing an RS-232 port was available back in the day, it’s become hard to find, inspiring [James] to design a completely new module based on an Arduino Nano.
