About the PanelGroup Base PCB

PanelGroup Base is an open source STM32 PCB design by OpenSkyHawk, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 98 × 78.5 mm, with 60 components from 34 distinct parts.

Its main chip is the STM32F103C8Tx, from the STM32 family. Other key parts include the SN65HVD230 and AMS1117-3.3. By type, the board carries 22 resistors, 15 capacitors, 10 connectors, 5 diodes, 3 ICs and 2 transistors.

From the project

DCS A-4E Skyhawk home cockpit — 3D-printed panels, custom PCBs, STM32/RP2040 firmware

Physical DCS A-4E Skyhawk home cockpit — 3D-printed panels, custom PCBs, and STM32 firmware for the DCS A-4E Community Mod. Controllers communicate over CAN bus.

Each physical panel group is driven by one STM32F103CBT6 MCU board. Boards communicate over CAN bus via Molex Mini-Fit Jr connectors. Panel breakout boards connect to their MCU board via 6- or 8-pin JST-XH harnesses. Firmware is built with PlatformIO.

PanelGroup Base: common questions

What microcontroller does the PanelGroup Base use?

The PanelGroup Base is built around the STM32F103C8Tx, from the STM32 family.

How big is the PanelGroup Base PCB?

The PanelGroup Base measures 98 × 78.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PanelGroup Base?

60 components, from 34 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 PanelGroup Base design files?

From the OpenSkyHawk/OpenSkyhawk 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 PanelGroup Base design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the PanelGroup Base 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.
