RedBoardThe RedBoard is SparkFun's take on the Arduino Uno. It combines the simplicity of the Uno's Optiboot bootloader (which is used in the Pro series), with the stability of the FTDI and a mini-B USB connector.
OpenScaleAn open source board for load cell reading and configuration based on the HX711 and ATmega328.
Easy DriverThe EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver).
Qwiic IMU BNO080The BNO080/BNO085 IMU has a combination triple axis accelerometer/gyro/magnetometer packaged with an ARM Cortex M0+ running powerful algorithms.
