Frequently asked questions
How do I connect it to an Arduino Nano?
Connect the module's TXD to the board's RX, RXD to the board's TX, and GND to GND. Use the 5 V output for 5 V boards.
Which voltage output should I select?
Choose the 3.3 V or 5 V output to match the logic level of your target board. Using the wrong level can damage a 3.3 V board.
