About the SkyRizz-ESPSOL PCB

SkyRizz-ESPSOL is an open source ESP32 PCB design by SkyRizzAI, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 40.6 × 40.6 mm, with 70 components from 35 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N16R8, from the ESP32 family. Other key parts include the MCP73831-2-MC, DW03D, ME6211C33M5, CH340C and SE050C2HQ1_Z01SDZ. By type, the board carries 26 resistors, 17 capacitors, 8 ICs, 4 transistors, 4 connectors and 3 switches.

It belongs with the iot & wireless, sensors and usb & debug tools designs in this gallery.

From the project

An open-hardware, coin-sized ESP32-S3 development board with an on-board secure element, 6-axis IMU, PDM microphone, buzzer, USB-C, and Li-Po charging — all on a 40.6 mm (1.6") round, 2-layer PCB.

The KiCad project lives in the SkyRizzAI/SkyRizz-ESPSOL repository on GitHub; these links point at the commit this page was built from.

SkyRizz-ESPSOL: common questions

What microcontroller does the SkyRizz-ESPSOL use?

The SkyRizz-ESPSOL is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the SkyRizz-ESPSOL PCB?

The SkyRizz-ESPSOL measures 40.6 × 40.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SkyRizz-ESPSOL?

70 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the SkyRizz-ESPSOL design files?

From the SkyRizzAI/SkyRizz-ESPSOL repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SkyRizz-ESPSOL design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which SkyRizzAI chose for the repository.

Can I test firmware for the SkyRizz-ESPSOL 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.
