Frequently asked questions
How do I wire it to a Raspberry Pi?
Connect the module's TX to the Pi's RX and RX to the Pi's TX, plus power and GND as in the listing's pin table. Raspberry Pi UART pins use 3.3 V logic, so confirm the logic levels match before connecting.
What power and antenna do I need?
Use a 5 V supply rated at 2 A or more, because transmission draws high peak current. Attach an antenna to the SMA or IPX connector before transmitting.
