Based on feedback the quad drivers has had a few changes
What's new:
Input/output pads changed so standard 0.1" molex connectors can be mounted
Groundplane changed to make soldering wires easier
Beam suppression jumpers replaced by a single solder jumper, that will enable beam suppression on all channels in one go
Solder jumpers on the back of the board to bridge the modulation inputs
Test points to measure current with a diode connected (0.1V / A)
Rest of specs remains the same:
Board size: 63x48mm
Output current: 0-2A modulation, 0-0.5A bias (2.5A total)
4 separate modulation inputs
5-24V supply voltage
Price stays at 60 euro.
Lots of people have asked me to do a dual channel version, so here we go:
Same specs as the quad above, just half the number of channels
Board size: 36x48mm
Price: 40 euro.
