1) 2x12v red LEDs

2) 2x5v LEDs

3) a fuse (see Frankenso part - I have those)

4) x8 low side LEDs

5) x6 high-side LEDs

6) 5.5mm barrel jack is what I use for those

Need to find larger pogo pins - current pins are smaller than connector holes on microRusEfi

LED board would use same footprint as real MRE board

the idea is for LED board to use # 6 bolts in order to sit on the board being test - # 6 bolts match existing mounting holes diameter perfectly.

LED board would be very dumb - no CPU no MCU. An external human would enable MRE self-stimulation and external human would look at the LEDs to decide pass/fail.

MRE would stimulate itself and output low-side injector and high-side ignition signals. LED board should display those outputs using LEDs

P100-E2 pogo pins seem relevant

Sockets

R100-2S solderable socket P100-4S solderable socket R100-1W wire wrap socket R100-2W wire wrap socket P100-4W wire wrap socket P100-5W wire wrap socket R100-3T crimp socket R100-4VW mystery socket Pogo pins are supposed to be used in compatible sockets. Pins have fairly short lifespans. When one breaks you'll be glad you used sockets instead of soldering directly to the pin.

There is a plan to make progress at https://github.com/rusefi/hw_microRusEfi/tree/master/test_fixture

@jharvey is on the job!
