This is the Adafruit Feather M0 RFM69 Packet Radio (433 or 900 MHz) - our take on an microcontroller with a 433 or 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.
In this Pro Trinket powered project, build and 3D print yourself a friend, an Adafriend! This little colorful guy with an eye responds to taps and vibrations, and shows emotion on its little LED matrix face with a sad, neutral, happy, or angry face. It plays tones that correspond to it's emotional state, and even sings some recognizable tunes and themes when it's in the mood! If left alone for too long it gets lonely, but pester your pet too much and it may get angry at you! Build yourself an Adafriend and keep it happy to sing along with the coolest cube around!
You want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. What now? You could give up OR you could just get our handy PWM and Servo FeatherWing. It's a lot like our popular PWM/Servo Shield but with half the channels & squished into a nice small portable size and works with any of our Feather boards.
Arduino is a great starting point for electronics, and with a motor shield it can also be a nice tidy platform for robotics and mechatronics. Here is a design for a full-featured motor shield that will be able to power many simple to medium-complexity projects. Build the kit, and learn how to use it with these detailed instructions.
