micro:bit pin map
Based on the official edge connector reference. This is not the Pico map: micro:bit pins are named P0, P1… and there are no GP or physical header numbers here.
Your T-type breakout adapter prints these names next to its legs. Revisions differ in layout and orientation, so always read the labels on your adapter. This course does not give breadboard row numbers for the adapter.
Big rings (front, left to right)
Small edge pins (via the breakout's labels)
Tinted pins are shared with the display, buttons or internal sensors. Beginner circuits here use P0, P1 and P2 only.
Record your board version to see V1 notes highlighted.
