Rover panel
About the Rover panel PCB
Rover panel is an open source PCB design by karimf1, published on GitHub under the MIT license. It is a 2-layer board measuring 110 × 46 mm, with 95 components from 43 distinct parts.
Other key parts include the LM5165XDRCR, INA228AIDGSR, LM339DR, SN74LVC1G08DBVR and SN74LVC1G74. By type, the board carries 38 resistors, 18 diodes, 18 capacitors, 12 transistors, 5 ICs and 3 connectors.
From the project
This repository is continuation of rover panel repo. Power panel PCB layout is implemented in KiCAD based of AutoCAD version of rover panel .
The PCB was missing. It sits on four standoffs on the panel plate, between the shunt and the signal connector, and does three jobs:
- precharge — it switches the pack through the panel's 22 Ω resistor R1 into the ESC bank, and holds contactor K1 open until the switched bus reaches ~90 % of the pack - interlock — K1's coil is energised through the E-stop loop and this board, so the board can open K1 but nothing on it can close K1 past an open E-stop - current sense — an INA228 on the panel's 0.75 mΩ shunt RS1, reported over I2C
