Pinout

Pin	Name	Type	Function
1	PC13	bidirectional	PC13 general-purpose I/O, 5V-tolerant. Additional functions: TAMP_IN1, RTC_TS, RTC_OUT1, WKUP2. Alternate function TIM1_BK. Supplied through the RTC domain power switch - limited to 3 mA sink and <= 2 MHz output at 30 pF load; not usable to source current.
2	PC14-OSC32_IN	bidirectional	PC14 GPIO / LSE oscillator input (OSC32_IN), 5V-tolerant. Alternate function TIM1_BK2. Supplied through the RTC domain power switch with the same 3 mA / 2 MHz limits as PC13.
3	PC15-OSC32_OUT	bidirectional	PC15 GPIO / LSE oscillator output (OSC32_OUT), 5V-tolerant. Alternate functions OSC32_EN, OSC_EN. Supplied through the RTC domain power switch with the same 3 mA / 2 MHz limits as PC13.
4	VBAT	power_in	Backup domain supply. Powers the RTC and backup registers when VDD is absent. Connect to 1.55-3.6 V battery or to VDD if backup domain isn't used. On packages without a dedicated VBAT pin it is bonded internally to VDD/VDDA.
5	VREF+	power_in	Positive reference input for the internal 12-bit ADC. Must be decoupled to VSSA. On packages without VREF+, this reference is tied to VDDA internally.
6	VDD/VDDA	power_in	Main digital and analog supply, 2.0-3.6 V. VDD and VDDA are bonded together on this package; decouple with 100 nF + bulk cap near the pin.
7	VSS/VSSA	power_in	Combined digital and analog ground return. VSS and VSSA are bonded together on this package.
8	PF0-OSC_IN	bidirectional	PF0 GPIO / HSE oscillator input (OSC_IN), 5V-tolerant. Alternate function TIM14_CH1. Used with an external 4-48 MHz crystal or clock input.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`stm32g030c6t6.step`	617 KB	You want the bare part, or you mark your own boards.
`stm32g030c6t6-etched.step`	5.1 MB	You want the part with `STM32G030C6T6` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 1248 faces against 747 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
