This is a scale model of the Seeed Studio XIAO ESP32C, an Arduino & CircuitPython capable RISC-V board with Wi-Fi, Bluetooth and USB-C that comes with an antenna and costs $4.99. The product page for this device can be found here.

It is intended for makers building electronics to include in their design process, as it removes the extensive process of measuring this part to fit when designing your wonderful lamps/clocks/robots/etc.

If you would like to view the 3D model in colour in your browser and with optional AR, this is available directly at the Shapr3D viewer here. To date, we have used it to at least make this wireless humidity and temperature sensor and probably other stuff too!

If you build something and use this as an asset, please make me happy by posting it in the makes section!

Tolerances

When designing things using this model in my experience adding 0.2mm around the board will lead to a tight fit that holds the device in place. However, your boards may have slight differences depending on the batch, or perhaps your printer settings will mean more or less of a gap is needed. 0.2mm is probably a good starting point.

Safety Note

This device gets a little warm, and has an unpopulated relatively large thermal pad on the underside. If you are going to enclose it please consider adding a heat sink and ventilation.

Versions

2023.10.04: Updated board thickness, USB-C port width and its offset to the board based on feedback.

2023.08.25: Merged assets into a single folder in Shapr3D project to make importing into other projects clean and added missing thermal pad on the underside of the board.

2023.08.24: Original upload.
