Joystick module with Nordic nRF52840 DK

Wiring for the Analog joystick (KY-023) on the Nordic nRF52840 DK (nRF52840-QIAA, 3.3 V logic), chosen with the same pin rules BoardPilot uses: default buses first, and no pins that are used for flash, USB, the debugger or booting.

Test code (Arduino)

The Arduino core for this board numbers its pins differently from the chip names, so no code is shown here. Use the pin names from your core’s variant file.

Arduino board: adafruit:nrf52:pca10056. Plug USB into the port on the short edge (interface MCU, J2) and set the power switch to ON; before the first Arduino sketch, burn the Adafruit bootloader and SoftDevice once.

Questions

Which Nordic nRF52840 DK pins do I use for the Joystick module?

GND → GND, +5V → VDD, VRX → P0.03 (A0) (P0.03), VRY → P0.04, SW → P1.03.

Does the Joystick module work with the Nordic nRF52840 DK at 3.3 V?

Yes: the Joystick module runs at 3.3 V and the Nordic nRF52840 DK uses 3.3 V signals, so no level shifting is needed.

BoardPilot checks this wiring in 3D as you build it, and finds crossed or missing wires on the real board.
