The Adafruit Feather RP2040 RFM69 board is another board Adafruit lovingly refer to as part of its ‘RadioFruits’ line of microcontrollers. The board is very similar to the RP2040 with LoRa, but this one features an RFM69 Packet Radio (868 or 915MHz). It’s great for sending packets of data between different boards
featuring the same type of radio.
You can communicate up to five kilometres, but of course that’s under ideal conditions and with a proper antenna. Speaking of antennas, you will need one for this board to work, and you can make your own with a small piece of wire, or you can buy one and use the on-board connector.
They give the Feather a 9/10, saying “A good low-cost radio and micro.”.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
