About the G3-native PCB

G3-native is an open source STM32 PCB design by pierrekin, published on GitHub. It is a 2-layer board, with 44 components from 15 distinct parts.

Its main chip is the STM32H745ZIT6, from the STM32 family. Other key parts include the USBLC6-2SC6 and AP2112K-3.3. By type, the board carries 32 capacitors, 3 ICs, 3 resistors, 2 connectors, 2 switches and 1 fuse.

From the project

- lib/ is the single source of truth for part choices. Each project's sym-lib-table / fp-lib-table point at it with ${KIPRJMOD}/../lib/.... - Live-share (shared hierarchical sheet) only blocks that are truly frozen. - Copy forward (KiCad Design Block) everything else, so each gen

- lib/ is the single source of truth for part choices. Each project's sym-lib-table / fp-lib-table point at it with ${KIPRJMOD}/../lib/.... - Live-share (shared hierarchical sheet) only blocks that are truly frozen. - Copy forward (KiCad Design Block) everything else, so each generation owns its copy and a divergence in one generation never breaks another.

G3-native: common questions

What microcontroller does the G3-native use?

The G3-native is built around the STM32H745ZIT6, from the STM32 family.

How big is the G3-native PCB?

The G3-native has 2 copper layers and is 1.6 mm thick.

How many components are on the G3-native?

44 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the G3-native design files?

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

Can I use the G3-native design in my own project?

The repository has no license, so all rights stay with pierrekin. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the G3-native 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.
