About the CAN HUB SMD PCB

CAN HUB SMD is an open source PCB design by TOBA-Robocon, published on GitHub. It is a 2-layer board measuring 45 × 45 mm, with 6 components from 2 distinct parts.

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。

CAN HUB SMD: common questions

How big is the CAN HUB SMD PCB?

The CAN HUB SMD measures 45 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CAN HUB SMD?

6 components, from 2 distinct parts. The full bill of materials is listed on this page.

Where can I download the CAN HUB SMD 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 CAN HUB SMD 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.
