ST2-USB is an advanced Satellite Antenna Tracking Interface for Yaesu (Or similar) Rotor Controllers based on LVB Tracker Firmware. Project uses PIC16F976A, 28PIN DIP. Firmware uses full A/D and EEprom capability of 876A and make setup a smooth process.

ST2-USB measures 14x8cm and is designed on a double sided PTH board. Its same as ST2-RS232 except that it has built-in USB interface using CH360G in SO16 package, pre-soldered for kits. 

Screw Terminals are used for Rotor Connections to simplify installation. You will have make a suitable cable to interconnect ST2 to Yaesu Rotor Controller.

ST2-RS232 and ST2-0816 USB supports Yaesu GS232, Extended GS232 and Easycomm commands, making it a suitable interface to use with NOVA, SatPC32 and many more, having above interface servers.

ST2-USB can be powered from USB port or from Yaesu Rotor Controller. A push powere change over switch is provided for this purpose.

ST2-USB Kits & Assembled, now includes a free powder coated metal case. CH360G requires a driver for WIN OS and is available for down load from this page. Driver creates a virtual COM port for your OS to work with SatPC32 or Nova. ST2-0816 was fully tested on WIN XP(SP2) and WIN7 Ultimate.

Important Note:
U4 (7805) in above picture is mounted on Top Side. In ST2-0816 PCBs, it should be mounted on bottom side due to SILK Errror. Please refer "Error Doc" for details.
