About the Iot PCB

Iot is an open source ESP32 PCB design by ckh7488, published on GitHub. It is a 4-layer board measuring 13.2 × 16.6 mm, with 21 components from 9 distinct parts.

Its main chip is the ESP32-C6FH4, from the ESP32 family. Other key parts include the QFN48_0P8_11P8X9P8. By type, the board carries 11 capacitors, 3 resistors, 2 ICs, 2 inductors, 1 crystal and 1 antenna.

It belongs with the iot & wireless designs in this gallery.

From the project

This side project keeps the RF learning work separate from the controller, camera, and outlet product schematics.

This side project keeps the RF learning work separate from the controller, camera, and outlet product schematics.

- Espressif ESP32-C6-MINI-1 V1.0 reference design - official source date: 2024-09-26 - 4-layer, official nominal 0.8 mm PCB, outline 13.2 mm x 16.6 mm - ESP32-C6FH4 QFN32 with embedded flash - PCB antenna and official shield-can geometry

MINI-1 was selected instead of WROOM-1 because it is the smaller, simpler C6 module and keeps the first RF A/B exercise focused on the crystal, RF supply, matching network, antenna, and return paths. The official WROOM-1 V1.2 source is retained…

Iot: common questions

What microcontroller does the Iot use?

The Iot is built around the ESP32-C6FH4, from the ESP32 family.

How big is the Iot PCB?

The Iot measures 13.2 × 16.6 mm, has 4 copper layers and is 0.91916 mm thick.

How many components are on the Iot?

21 components, from 9 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 Iot design files?

From the ckh7488/iot 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 Iot design in my own project?

The repository has no license, so all rights stay with ckh7488. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Iot 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.
