Description
OnStep telescope mount controller (base on Howard Dutton project visit [group](https://onstep.groups.io/g/main/wiki/3860) for more information.)
This design for [ESPDUNO-32 (HW-707)](https://github.com/SmartArduino/SZDOITWiKi/wiki/ESP8266---ESPduino-32) board
3D model for printing on [Thingiverse](https://www.thingiverse.com/thing:4750134)
NOTE for ST4 need remove resistro R14 and Blue LED on ESPduino-32s board !!!
