About the APX DEVBOARD PCB

APX DEVBOARD is an open source STM32 PCB design by Gabouin, published on GitHub under the MIT license. It is a 2-layer board measuring 23.4 × 40.3 mm, with 26 components from 12 distinct parts.

Its main chip is the STM32G431CBT6, from the STM32 family. Other key parts include the XC6206PXXXMR. By type, the board carries 12 capacitors, 7 resistors, 2 ICs, 2 connectors and 1 LED.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

simple cost-effective devboard made for RESOLUTION

APX DEVBOARD is a STM32 based devboard designed with GPIO pins, buttons and an LED

- STM32G431CBT6 MCU 32-Bit 170MHz 128KB (128K x 8) FLASH 48-LQFP (7x7) - 8 GPIO pins to help make any hardware project - GPIO linked LED to program it without needing an external LED - GPIO linked button to use it without needing an external button - BOOT and RESET buttons - USB-C input - GND pour on both layers to reduce noise - Amiri silkscreen for a professional look - Original edge cut to look cool lol - Small size of 2.3*3.7 cm

APX DEVBOARD: common questions

What microcontroller does the APX DEVBOARD use?

The APX DEVBOARD is built around the STM32G431CBT6, from the STM32 family.

How big is the APX DEVBOARD PCB?

The APX DEVBOARD measures 23.4 × 40.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the APX DEVBOARD?

26 components, from 12 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the APX DEVBOARD design files?

From the Gabouin/APX_DEVBOARD repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the APX DEVBOARD design in my own project?

Yes, under the terms of its MIT license, which Gabouin chose for the repository.

Can I test firmware for the APX DEVBOARD without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
