Inkplate 13SPECTRA – Jumpers
Inkplate 13SPECTRA features several on-board jumpers, which can be used to modify the behaviour of certain components. Some jumpers are connected by default, while others need to be manually shorted.
See the table below for detailed explanation of each jumper's function:
| Jumper | Default State | Function |
|---|---|---|
| JP1 | NC (connected) | When shorted, it provides a connectoin (on oin IO16) to IO Exapander's INT pin, effectively controlling it |
| JP2 | NO (not connected) | When shorted, it connects RTC clock output to IO2. |
| JP3 | 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. |
| JP4 | NO (not connected) | When shorted, it connects SPI Chip Select line to GPIO15. |
| JP5 | NO (not connected) | When shorted, it connect the pin P1_1 to battery voltage measurement circuit. |
| JP6 | NC (connected) | When shorted, it provides a connection (on pin P1_2) to onboard MOSFET that powers the microSD card. |
