Rm electrical chassis
About the Rm electrical chassis PCB
Rm electrical chassis is an open source PCB design by ut-ras, published on GitHub. It is a 4-layer board measuring 80 × 80.1 mm, with 47 components from 36 distinct parts.
Other key parts include the RT6285GSP. By type, the board carries 24 connectors, 7 diodes, 7 resistors, 6 capacitors, 1 IC and 1 fuse.
From the project
This project contains the chassis board, which routes power and CAN to the wheels from the PMM and the Dev Board, respectively. Also, a buck converter that drives the 19V power needed for the CV board. This is sent up the slip ring.
