[PSUBS-MAILIST] SCM v3

[Jon Wallace via Personal_Submersibles]

I've finished my Submarine Control Manager circuit board design, a third revision, and will be ordering it as soon as things calm down a bit around the world.  Unfortunately some of the suppliers that I need to order parts from are closed due to the virus, so I can't get all the components right now.  Board dimensions are 5x7 inches, 127x177mm for our friends that are still using that outdated metric system.  :)
INPUTS:16 Analog (voltage)8 Analog (current)8 TTL Serial8 I2C
OUTPUTS:16 Digital8 Digital/PWM
