 | PCB Name | CAN ports | 12V outs | Primary role |
 |----------|-----------|----------|-------------|
 | **Start** | 1 | 1 | Bus origin at PDH side |
-| **Minor** | 3 | 1 | Mid-chain node |
+| **Minor** | 3 | 1 | Single wheel module — CANcoder + 2 motors |
 | **Middle** | 3 | 2 | Mid-chain node + power distribution |
 | **Major** | 6 | 2 | Heavy distribution — end of main runs |
 | **Endz** | 1 | 1 | USB diagnostic tap — serves as first OR last device in chain |
 
+**Minor — single wheel module design:**
+- 1 CANcoder (CTR Electronics CAN FD magnetic encoder for steering feedback)
+- 2 motors (typically drive motor + steering motor, or drive + mechanism)
+- 1 12V output for accessories
+
+Minor was designed for MK4i swerve modules — one Minor per wheel handles the CAN bus connections for the encoder and both motors. Clean single-point connection for each corner of the robot.
+
 **Note on overlap:**
 - Start and Endz both serve end-of-chain positions (first or last device)
 - Minor and Middle both have 3 CAN ports — Middle adds a second 12V output for power distribution
