====== 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 [[firmware|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,<key>x</key>|Resets motor <key>x</key>|
|?motor.ref.high[<key>x</key>]|checks the reference flag of motor <key>x</key> on the high side|
|?motor.ref.low[<key>x</key>]|checks the reference flag of motor <key>x</key> on the low side|
|?motor.address.[<key>MOTOR</key>]|checks the motor address used for <key>MOTOR</key>|
==== 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 [[singleboard#mainboard_flat_cable_connections|here]]. Afterwards, enter [[mm|MM]] or opmode in brewcmd.
<konsole mm>
?motor.address[motorname]
#This will output the current motor address number, verify this is the one you want to change\\
!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.
