T he Adafruit Feather RP2040 RFM95LoRa Radio board, aka ‘RadioFruits’, is Adafruit’s take on a microcontroller with integrated long-range (LoRa) packet radio transceiver, along with a built-in USB and battery charging system. This is the perfect microcontroller board for creating wireless sensors that have a longer range and require less power than other wireless solutions like Bluetooth.
The board features an RP2040 chip running at 133MHz, the same as you can find on a Raspberry Pi Pico. You also get a generous 8MB of on-board QSPI
flash and 264kB of RAM, plus on-board RGB LED, STEMMA QT connector, and lots of GPIO pins.
Between the on-board battery management, LoRa radio, and RP2040, it would be hard to beat this little board for creating an outdoor sensor network.
They give the Feather a 10/10, saying “Simple long range sensing”.

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.
