5.2.1 Hardware Setup Introduction

The hardware board is build up based on MSPM0G3507 Launchpad and BQ76952EVM.

The hardware connection can refer to Figure 5-11. You only need to connect power and I2C between MSPM0 launchpad (SDA: PB3, SCL: PB2)and BQ76952EVM (SDA: J17 PIN3, SCL:J17:PIN2). Rememeber to remove the cell simulation jumpers and add jumpers for I2C pullup.

If you want to use MSPM0G3507 launchpad in communication data input mode, no other hardware change is needed compared with default MSPM0G3507 launchpad hardware set.
