About the 偽C610 PCB

偽C610 is an open source STM32 PCB design by TOBA-Robocon, published on GitHub. It is a 2-layer board measuring 22 × 44.8 mm, with 47 components from 25 distinct parts.

Its main chip is the STM32F303K8Tx, from the STM32 family. Other key parts include the Regulator_3.3, NJM7812, Regulator_5.0, MCP2561-E-SN and IR2302. By type, the board carries 14 resistors, 13 capacitors, 7 ICs, 4 transistors, 4 diodes and 3 connectors.

From the project

鳥羽商船Aチームが2025年度のNHK高専ロボコンで使用した基板(公開用に多少編集済み)

付属のXT60に給電することで分岐先のUSB-Cの電源ラインに電源を供給できる。

電源を供給することで後述する「偽C610(C810)」を駆動させることができる。

本番で使った基板にはれな子のシルクが乗っているため、部内では「れな子」と呼ばれていた。

ESP32とF405RGTがついている。Dualshock4の値をESP32で受け取ってCANバスに流し散らかす。

Dualshock4の値を使って各機構の処理をし、4本のUSB-C_CANで各基板にデータを転送する。

偽C610: common questions

What microcontroller does the 偽C610 use?

The 偽C610 is built around the STM32F303K8Tx, from the STM32 family.

How big is the 偽C610 PCB?

The 偽C610 measures 22 × 44.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the 偽C610?

47 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the 偽C610 design files?

From the TOBA-Robocon/NHK_2025_circuit_public_var repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the 偽C610 design in my own project?

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

Can I test firmware for the 偽C610 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.
