| J4(1) - GND | Ground |
| J5 | I2C 4-pin connector for the EV2300/2400 interface board |
| J6 | Input source Micro B USB port |
Table 1-3 lists the jumper and shunt installations available on this EVM and their respective descriptions.
| Jack | Description | BQ25611D Setting | BQ25619 Setting |
|---|---|---|---|
| JP1 | I/O Pullup rail selection. Selection will have either BAT or SYS as the pullup rail for SDA, SCL, CE, PG, STAT, and INT pins | PULLUP to SYS | Short PULLUP to SYS |
| JP2 | Remote BATSNS pin connection to Battery input terminal. Disconnect if sensing battery voltage remotely through J4(2). If disconnected with no input on J4(2), charger BATSNS will default connect to BAT pin internally. | Installed | Installed |
