Looking good !!!

Hello Mark,

The driver module for the VLA-500 is basically the same circuit that they offer in the BG2A dev kit. http://www.pwrx.com/pwrx/docs/bg2a_application_note.pdf
It has some modifications to the board but not too many. I do plan to add hardware overcurrent protection like in the cougar as well. This will be good for those mishaps.

This will be directly on the main board so it can serve to protect the entire output. it wont matter what driver board is connected, because the pwm will stop before it gets to the driver.
