Which micro:bit pins does the Hummingbird Bit use?

The Hummingbird Bit uses the following pins on the micro:bit:

PIN 0: Used to control the buzzer on the Hummingbird Bit

PIN 1: Exposed on the Extensions Port

PIN 2: Directly controls single color LED port 2

PIN 8: Directly controls single color LED port 3

PIN 13: SCK signal for SPI communications to the Hummingbird’s daughter microcontroller

PIN 14: MISO signal for SPI communications to the Hummingbird’s daughter microcontroller

PIN 15: MOSI signal for SPI communications to the Hummingbird’s daughter microcontroller

PIN 16: SS signal for SPI communications to the Hummingbird’s daughter microcontroller

PIN 19: Exposed on the Extensions Port

PIN 20: Exposed on the Extensions Port

Pins 3-7 and 9-12 on the micro:bit edge connector are not used by the Hummingbird Bit.
