Along that sharing line of thought, I've just found a pwm motor controller that is 10 for $14 motor control, can be used with 5 volt drive but should really shine where a mesa card has 12 volt field power to drive it. 40 volts max psu, 20 kilohertz pwm/pdm drive, 13 amps continuous, 50 surge. No direction but for running pumps and other such tom-foolery, it looks like the ideal slightly over half a cubic inch of solution. I just bought ten of them to play with, look for X002b3VVUN on amazon. I am not happy with the board I'm controlling my mister air compressors with, runs too hot on 5 volt drive but I'll try it for that in a day or 2. <9.5milli-ohms on R at 5 volts drive from a std bob. google search for: <http://www.aosmd.com/res/data_sheets/AOD4184A.pdf> for the spec sheet, two of these on a teeny board. I have 5 of the MPJA.com, $6.95 each, #36394 12 volt diaphram air pumps lined up on a 3d printed mounting plate sitting a soft rubber mounts, all 5 draw a bit more than an amp combined from 12 volts, makes more than enough air to run the mister on my 6040 mill. I can't hear them running over the fan in the vfd. I can't hear myself think when the 2hp shop compressor is burning itself up supplying the air for that, and this teeny little gizmo should work just fine for that.
