Hello,
This is a EQ mount controller(for stepper motor).
I just finished the PCB circuit and firware.Plan to do a plastic mould for it.
Here is some basic feature:
Three stepper motor driver ouput, for RA,DEC, and focus motor.
Step motor type: 2 phase. Resistance: 10ohm. Output current:MAX 1A
1/16 microstep.PWM control
Maxium GOTO SPEED:about 300X
Resolution: about 0.5 arcsec/step( when using 1:5, 1.8degree motor at 144 gear mount)
I write a ASCOM driver ,it can connect SKYMAP ,starrynigh etc to GOTO.
Suport ASCOM pulseguide command, and K3CCD PISCO guide command via RS232
One 6pin RJ-12 guide port(ST-4 type)
Two RS232 port.One is use for main RS232 communication with computer,one is used for connect Pocket PC (for the furture electic sky map on windows Mobile system)
It has a bootloader, the fireware can be upgrade via RS232.And it is openning source code( C language)
