4.1.5.2.3. Master TMS570 `v1.2.2` Pinout

Important

The following description only applies for the BMS-Master hardware version v1.2.2.

Important

Due to the removal of the peripheral SBC, the pinout of BMS-Extension connector (J9002) has changed compared to previous hardware releases.

Hint

All connector pinouts described below follow the Convention for Molex Micro-Fit 3.0 Connector Pin Numbering, Convention for Samtec Edge Rate connectors, Convention for Mictor Pin Numbering or Convention for Wuerth WR-MJ connector.

This section describes the pinout of all connectors on the BMS-Master v1.2.2.

4.1.5.2.3.1. Supply
