About the CandleLightfd-S01 3x3 PCB

CandleLightfd-S01 3x3 is an open source STM32 PCB design by linux-automation, published on GitHub under the CERN-OHL-1.2 license. It is a 2-layer board measuring 119.1 × 80.4 mm, with 41 components from 23 distinct parts.

Its main chip is the STM32G0B1CBT, from the STM32 family. Other key parts include the MCP1754ST-3302E/MB and TJA1051T/3. By type, the board carries 11 capacitors, 8 resistors, 5 test points, 4 ICs, 4 crystals and 3 diodes.

From the project

USB CAN-FD interface based on the STM32G0 that works well with gs_usb on Linux

candleLight FD is a modern, CAN-FD capable version of the candleLight based on a STM32G0B1 microcontroller.

Out of the box it comes with a single CAN channel placed. But footprints for a second CAN channel are available.

The candleLight FD is - like the candleLight - licensed under the CERN OHL v1.2 open hardware license.

The candleLight FD is available from Linux Automation as a SMD-assembled and functionally tested kit.

CandleLightfd-S01 3x3: common questions

What microcontroller does the CandleLightfd-S01 3x3 use?

The CandleLightfd-S01 3x3 is built around the STM32G0B1CBT, from the STM32 family.

How big is the CandleLightfd-S01 3x3 PCB?

The CandleLightfd-S01 3x3 measures 119.1 × 80.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CandleLightfd-S01 3x3?

41 components, from 23 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 CandleLightfd-S01 3x3 design files?

From the linux-automation/candleLightFD repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the CandleLightfd-S01 3x3 design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which linux-automation chose for the repository.

Can I test firmware for the CandleLightfd-S01 3x3 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.
