There are popular and quite cheap amateur telescope mounts from different vendors: Sky-Watcher, Celestron and so on.
Most of that mounts contains motors and some controller schematic. User can control this devices in different ways. One way is to use mount’s handcontroller, other way is connect to computer and use some software to control and guide the telescope. Such connection can be made through special adapters (often called eqmod). Technically this adapter is just some kind ot serial converter, RS232 to UART (TTL) or USB to UART.
Here I’m describing a very reliable and simple adapter with galvanic isolation that I was developed and made.
