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 GPIO15 to the microSD Chip Select (CS) line. Needed for SD card communication. |
| JP3 | NC (connected) | Connects GPIO39 to the microSD card power enable line or interrupt (depending on routing). May be used for SD power switching or custom IRQ setups. |
| JP4 | NO (not connected) | Connects GPIO0 to a solderable pad. It is used to manually pull GPIO0 low, which is often required to enter firmware flashing mode (ESP32 bootloader). |
| JP5 | NC (connected) | Connects GPIO0 through a capacitor to GND. It provides filtering or a soft pull-down to help stabilize boot mode logic and is typically left connected. |
| JP6 | NC (connected) | Connects GPIO34 to the interrupt output of the touch controller (INT B), which is required for interrupt-driven touch detection. |
| JP7 | NC (connected) | Connects the SD card power enable signal to the power MOSFET; if left open, the SD card will not be powered by software control. |
| JP8 | NC (connected) | Connects VBAT (battery voltage) to the frontlight MOSFET, controlling whether the frontlight is powered via battery input. |
