Designed in Discord, assembled in China. This board covers all the needs of the stepper or servo based OSSM.

For the servo based OSSM it simply plugs into the top of the servo and power is fed through so that you need not worry about DC to DC voltage conversion.

Zero Soldering required

Built with an ESP32 at its core, it is a great choice for many projects!
Some other features;

Colour changing LEDS (ohhhhhhh!)
Remote control connector, for wired control
Sensorless homing - no more limit switches
Auto stroke detection - no crashing
Extra IO for accessories ;)
Power supply protection - lets you use a smaller supply
Purple PCB (OSSM PCB and Remote)- Much Style!

350mm Linear Rail - Stainless Steel

We've bought dozens of different rails, and they are all totally hit or miss on quality. We have finally been able to find a good source for really nice hard chrome plated rail! This means they will not rust or corrode, look beautiful, and they run very smooth. If you don't want to take the gamble on AliExpress, this is for you!

Rails come with a thick packing oil on them. For complete silence we recommend lubricating with grease!

- PS hard chrome ≠ stainless steel, but "hard chrome" doesn't mean anything to a lot of people, so we call it stainless just for simplicity.
