Mapped source · ST NUCLEO-G071RB product pageOfficial- STM32G071RB GPIO is 3.3 V; pins are not 5 V tolerant. Mapping per ST UM2324 / mbed PinNames.h.
- D0/D1 connect to USART1 (PC5 = RX, PC4 = TX) by default; D14/D15 are I2C (PB9 SDA, PB8 SCL).
- DAC outputs: DAC1 on PA4 (A2) and DAC2 on PA5 (D13). ST Morpho CN7/CN10 expose all other ports.
