From DIDEAS Wiki
Rev B is a green color PCB with white silk screen :
"medialab/mm32brk.pcb REVB 031505"
- MM32 ribbon cable (2)
- Power (1)
- Analog Inputs (16)
- Analog Outputs (4)
- PID ANA-IO (1)
- Some power supply decoupling caps on pg3 of SCH have the wrong orientation, populated on PCBs correctly
- 4 groups of LEDs indicate the presence of power and the state of the fuses.
- Normally the LEDs on either side of the fuse should be dark – when a fuse blows these LEDs should be visible.
- LEDs adjacent to the power connectors indicate the presence of power
FUSES : the fuses socket may be populated with a shorting wire, a fast blow fuse, or a resistors which will act like a slow blow fuse.
