Adafruit Feather 32u4 RFM95 LoRa Radio – 868 or 915 MHz: This is the Adafruit Feather 32u4 LoRa Radio (RFM9x) – our take on an microcontroller with a “Long Range (LoRa)” packet radio transceiver with built in USB and battery charging. Its an Adafruit Feather 32u4 with a 868/915 MHz radio module cooked in! Great for making wireless networks that can go further than 2.4GHz 802.15.4 and similar, are more flexible than Bluetooth LE and without the high power requirements of WiFi. Read more.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
