Main 2026 V1 design files

The KiCad project lives in the Gamu2124/RCJ2026-Korea_PCB-design-files repository on GitHub; these links point at the commit this page was built from.

Main 2026 V1: common questions

What microcontroller does the Main 2026 V1 use?

The Main 2026 V1 is built around the XIAO-ESP32-S3-DIP_USS, from the ESP32 family.

How big is the Main 2026 V1 PCB?

The Main 2026 V1 measures 156.7 × 149.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Main 2026 V1?

127 components, from 45 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 Main 2026 V1 design files?

From the Gamu2124/RCJ2026-Korea_PCB-design-files 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 Main 2026 V1 design in my own project?

The repository has no license, so all rights stay with Gamu2124. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Main 2026 V1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
