Frequently asked questions
How do I connect this module to a microcontroller?
Connect the module's TX to the microcontroller's RX and its RX to the microcontroller's TX, with a common ground. Power the module from a supply that matches the datasheet, and confirm the logic level in the datasheet before wiring.
Can I connect it directly to a 5V Arduino board?
Wi-Fi modules of this type normally use 3.3 V logic. Connecting the TX pin directly to a 5 V board can damage the module, so use a level shifter on the signal lines when working with 5 V boards.
