The UAL (Developed/Designed in 2020 by Walex and Nitewing based on Tarla76’s concept) is an Addon for R2. The sketches are configurable and there are many ways to connect/control it:
- via switch / button
- I2C
- Serial RX/TX
Available at shop.printed-droid.com


UAL uses AstroComms Droid Protocol (ACDP) for receiving orders.
This is an example of a valid command: /AC/UAL/S01C01B020F050W1000
Please note that you need to add a carriage return after each command.
Every ACDP must start with /AC to specify an AstroCommms device it’s being addressed
and after that /UAL must be written to tell the protocol you are talking to an UAL unit.
Addressing its completing by adding / to the command.
