Notes
- Note 1 - 1K ballast LED resistors. Pick value for how bright you want LEDs at your operating voltage.
- Note 2 - R34 and R35 are 2.2K I2C terminators. Needed for 3.3V operation and 400 KHz operation. R36 is INT* pullup.
- Note 3 - LEDs - I like diffused Orange LEDs. I don't like clear LEDs.
- Note 4 - Pick the height you like. I like 6mm high. You might like taller if you use keycaps.
