About the Jchc1-hardware PCB

Jchc1-hardware is an open source ESP32 PCB design by GutFarms, published on GitHub. It is a 4-layer board measuring 100 × 70 mm, with 15 components from 15 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N16R8, from the ESP32 family. Other key parts include the AMS1117-3.3, C167271, 1V8, TXS0108EPWR and INA219AIDCNR. By type, the board carries 6 ICs, 5 connectors, 2 switches, 1 fuse and 1 inductor.

From the project

1. Replace placeholder module footprints with exact library parts (ESP32-S3-WROOM-1, USB-C, regulators). 2. Schematic Editor → Annotate → Assign footprints from ../manufacturing/bom.csv. 3. Update PCB from Schematic, then route remaining signals (UART, I2C, USB). 4. Run DRC. Expo

Update PCB from Schematic, then route remaining signals (UART, I2C, USB). 4. Run DRC. Export Gerbers to ../manufacturing/gerbers/.

The PCB file is a placement + plane starting point, not a finished DRC-clean route. Expect a short KiCad session to finish nets before fab.

Jchc1-hardware: common questions

What microcontroller does the Jchc1-hardware use?

The Jchc1-hardware is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the Jchc1-hardware PCB?

The Jchc1-hardware measures 100 × 70 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Jchc1-hardware?

15 components, from 15 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 Jchc1-hardware design files?

From the GutFarms/jchc1-hardware 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 Jchc1-hardware design in my own project?

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

Can I test firmware for the Jchc1-hardware 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.
