From the project

5x5 macro board using the NRF52840, ZMK and Zephyr

Third iteration of my 5x5; - based on zmk, using the nicenano2 board / Supermini RF52840

Questions: - Can the LDO keep up with 25 sk6803s?

25 * 5mA = 125mA, within range of charger and ldo on nicenano2

- Where are the specific pins for spi / i2c?

RF52840 can reconfigure its pins, so can be assigned to work well with whatever layout we want.

- foostan: corne / crkb: the first time I saw sk6812 in mini-e variant.
