Inkplate 6 – Jumpers
Inkplate 6 features several on-board jumpers, which can be used to modify the behavior of certain components. Some jumpers are connected by default, while others need to be manually shorted.
See the table below for a detailed explanation of each jumper's function:
Board jumpers
| Jumper | Default State | Function |
|---|---|---|
| JP1 | NO (not connected) | When shorted, it keeps the microSD card powered at 3.3v at all times. Useful for troubleshooting, but not ideal for low-power applications. |
| JP2 | Connected to IO34 by default | Switch between connecting the INTB pin of the IO expander to the IO34 pin of the ESP32 or make that pin user-accessible. |
| JP3 | NC (connected) | When shorted, it provides a connection to the onboard MOSFET that powers the microSD card. |
| JP4 | NC (connected) | When shorted, enables the Chip Select function for communication with the microSD card. |
| JP5 | Connected to INT by default | Switch between a digital, open-drain, active low interrupt output and a programmable digital square-wave output that can be used as a system clock. |
| JP6 | NC (connected) | When shorted, it connects the battery terminal to the MCP73831. |
