PCB has a built-in DCDC converter to step down to 6-12V (so you can adjust the max fan speed), 6 channels using the LM3414 (each with pot to adjust current) and Wemos/PCA9685 for PWM dimming. Everything is surface mount so you can mount the board directly to the heatsink to cool the drivers.
If you're interested i could swap the Wemos out for 2 extra channels, although you'd need an extra connector then for PWM. |
That is rad!
I wouldn't mind one of those as is! I can always piggyback another board or two off of the PWM pins of the Wemos, since I need several identical channels anyway. One of those boards as is, and another with a couple additional drivers instead would be extremely handy. I need 8 drivers total, but only six channels of control. One of those boards with a blueacro two-channel driver board piggybacking along work be perfect.
Do you have any finished boards yet, or just the files? I'm definitely interested either way.
