Single Board Electronics
The single board electronics, sometimes referred to new electronics are usually used in the MKIII Brewers. There's a very small numbers of MKIV brewers that may run a single board electronics. The single board electronics consist of the primary power supply¹ (PPS), lamp control board and the high voltage module. There are two version of the single board electronics, V1 and V2. See here for firmware programing instructions.
¹Note, both multiboard and single board electronics both have an PPS, however the multiboard uses a 24V/15V/5V power supply while the single board electronics uses 24V/12V/5V power supply. The latest brewer's produced by Kip and Zonen (around Brewer # 250) uses the TDK-Lambda NV175 series power supply. The single Electronics board uses NV1-4G5TT, where the multiboard uses the NV14G5FF.

Note 1: Top Refers to the connector on the stop of the ribbon connector stack on a V1 board when looking at it on a birds eye view. For V2 boards, it is the connector closer to the bottom of the board.
Note 2: From the table above, J2 is the connector on the top right of the board, and going left. J7 is on the bottom right of the board.
Note 3: [] indicates 12V pair and () indicates 24V pair and bold indicates jumper default

Commands
Frequency used commands in MM
| Command | description |
|---|---|
| I,X | Resets motor X |
| ?motor.ref.high[X] | checks the reference flag of motor X on the high side |
| ?motor.ref.low[X] | checks the reference flag of motor X on the low side |
| ?motor.address.[MOTOR] | checks the motor address used for MOTOR |
Changing Motor Address
The motor address can be changed in event of a bad motor driver or circuitry. This will require the ribbon cable to be physically moved to another connector as laid out here. Afterwards, enter MM or opmode in brewcmd.
!motor.address[motorname] 7 #replace 7 with the actual address you'd like to change to
i,10 #replace the 10 with the original address, this will reinitialize the motor
save #once you verify everything is working as expected, you can save which will use up on of the save slots. #otherwise when the brewer restarts, it'll be using the original motor address.
