Showing 24 of 24 pins

Simplified diagram, grouped by function — not to physical scale. Pin data is source-backed; verify against the linked documentation.

Hover, tap, or focus a pad to inspect a pin. Use arrow keys to move between pins.

EFR32MG24 GPIO uses the VMCU 3.3 V domain; the 5 V pad is USB power, not a logic level.
VREFP is an ADC reference input and must not be treated as a general power output.
mikroBUS signals are duplicated on the breakout pads; the Qwiic connector uses its separately documented PC05/PC04 I2C pair.

Full pin list, synchronized with the board drawing.
