STM32G030 Core Board 1.0
Overview
The WeAct Studio STM32G030 Core Board provides an affordable and flexible way for users to try out new concepts and build prototypes with the STM32G030F6 microcontroller. This compact development board is designed for space-constrained applications while maintaining essential functionality.
The board requires an external ST-LINK or compatible SWD programmer for flashing and debugging, as it does not include an onboard debugger.
Hardware
WeAct STM32G030 provides the following hardware components:
STM32G030F6P6 microcontroller in TSSOP-20 package featuring 32 Kbytes of Flash memory and 8 Kbytes of SRAM
Compact form factor optimized for embedded applications
Exposed SWD header for programming and debugging (SWDIO, SWCLK, GND, 3V3)
One user LED connected to PA4 (blue LED)
NRST button for manual reset
Flexible board power supply:
External 3.3V supply via power pins
5V input with onboard regulator
All GPIO pins broken out for maximum flexibility
More information about STM32G030F6 can be found in the STM32G0x0 reference manual [1] and STM32G030x6 datasheet [2].

Connections and IOs
Each of the GPIO pins can be configured by software as output (push-pull or open-drain), as input (with or without pull-up or pull-down), or as peripheral alternate function. Most of the GPIO pins are shared with digital or analog alternate functions. All GPIOs are high current capable except for analog inputs.
Default Zephyr Peripheral Mapping:
UART_1 TX/RX : PB6/PB7 (Primary Console)
UART_2 TX/RX : PA2/PA3 (Secondary UART)
I2C2 SCL/SDA : PA11/PA12
SPI1 SCK/MISO/MOSI : PA1/PA6/PA7
User LED : PA4 (Blue LED)
SWD Interface : PA13 (SWDIO), PA14 (SWCLK)
System Clock
The WeAct STM32G030 board is configured to use the internal HSI oscillator at 16 MHz with PLL to generate a system clock of 64 MHz. The board also includes LSE crystal support for RTC applications.
Programming and Debugging
The weact_stm32g030_core board supports the runners and associated west commands listed below.
| flash | debug | rtt | debugserver | attach | |
|---|---|---|---|---|---|
| jlink | ✅ | ✅ | ✅ | ✅ | ✅ |
| openocd | ✅ | ✅ (default) | ✅ | ✅ | ✅ |
| stm32cubeprogrammer | ✅ (default) |
WeAct STM32G030 board requires an external ST-LINK/V2 or compatible SWD debugger for programming and debugging. Connect your debugger to the SWD header:
SWDIO (PA13)
SWCLK (PA14)
GND
3V3 (optional, for powering the board)
Flashing
The board is configured to be flashed using west STM32CubeProgrammer [3] runner, so its installation is required.
Alternatively, OpenOCD or JLink can also be used to flash the board using
the --runner (or -r) option:
$ west flash --runner openocd
$ west flash --runner jlink
Flashing an application to WeAct STM32G030
Connect your ST-LINK or compatible programmer to the SWD header on the board.
Here is an example for the Blinky application.
# From the root of the zephyr repository
west build -b weact_stm32g030_core samples/basic/blinky
west flash
You will see the blue LED on PA4 blinking every second.
Debugging
You can debug an application in the usual way. Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b weact_stm32g030_core samples/hello_world
west debug
Serial Console
The primary serial console is available on USART1 (PB6/PB7) at 115200 baud. Connect a USB-to-serial adapter to these pins to access the Zephyr shell and console output:
TX: PB6
RX: PB7
GND: GND
