We are excited to launch our new Rodeostat M4 version! The new design uses the Adafruit ItsyBitsy M4 Express microcontroller board instead of the Teensy 3.2 board which is currently unavailable. The new design offers the same functionality and currently we are open for pre-orders at our online store! You can order a Rodeostat with ItsyBitsy M4 Express using this link below. We expect to start shipping orders in 2 weeks!
