Showing 40 of 40 pins

Simplified technical illustration. Pin data is source-backed; verify against the linked documentation before wiring.

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

Signals are 3.3 V logic and not 5 V tolerant; pins 37 and 40 are ADC analog inputs (1.8 V max), not GPIO.
Pin 38 is a 1.8 V reference output, not GND. SoC labels are Rockchip RK3568 GPIOn_xn bank names.
Pins 3/5 and 27/28 are the two I2C buses; pins 19/21/23/24 are SPI; pins 8/10 are UART (ttyS0).
