Inkplate 6FLICK – Jumpers
Inkplate 6FLICK features several on-board jumpers that 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 or logging during deep sleep, though not ideal for low-power use. |
| JP2 | NC (connected) | Connects the microSD Chip Select line to IO15 (SPI_CS) on the ESP32. Cut it to drive the card's CS from the GPIO15 breakout pad instead. |
| JP3 | NC (connected) | Selects what the RTC drives on IO39: its interrupt output, or the CLKOUT square-wave output. Nothing to do with the microSD card. |
| JP4 | NO (not connected) | Shorts out R58, the 47 Ω series resistor on the GPIO0 to EPD_CL clock line. Only for signal-integrity experiments on the e-paper clock. |
| JP5 | NC (connected) | Connects C61, a 100 pF filter capacitor, to that same EPD_CL clock line. Leave it connected unless you are deliberately tuning the clock edge. |
| JP6 | NC (connected) | Connects IO34 to INTB, the interrupt output of IO expander 1. Cut it to free IO34 for your own use. |
| JP7 | NC (connected) | Connects SD_ENABLE to pin P1-5 of IO expander 1, letting the library switch microSD card power on and off. |
| JP8 | NC (connected) | Connects V_BAT_MOS to pin P1-1 of IO expander 1. This enables the battery voltage divider, so battery voltage is only measured when requested. |
