In stock, ready to ship.
Originally part of the Ultibots FSR Endstop kit (now out of stock), these controllers employ an ATTiny861A. They can be used for their original purpose right out of the box, or for less than the price of an ATTiny861A you get a whole breakout board with microcontroller, power protection, decoupling caps, 4 LEDs, pull-up resistors on some inputs, all for less than the price of the microcontroller itself. Great for custom projects!
