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 FTDI-232RL chip on a small carrier board. FTDI232RL is
in a SSOP28 package. This package is hard to solder by most
homebrewers. I made a small board with standard 0.1inch headers on
which FTDI chip will be pre-soldered.
Screw Terminals are used for Rotor Connections to
ST2-USB has Bi-Directional data flow, from PC to ST2
& St2 to PC. An FTDI232RL chip is used for USB connectivity. You
will be required to install FTDI USB drivers which are available from
ST2 and ST2-USB supports 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 three pin sil header is provided for power
Kits are supplied with LCD and 4 Push Button Keyboard, keeping in mind
Operation at Radio Amateur Stations.
ST2-USB Kits & Assembled now includes a free
powder coated metal case.
