About the Atomic01 PCB

Atomic01 is an open source ESP32 PCB design by rajeev2705, published on GitHub. It is a 2-layer board measuring 86.6 × 71 mm, with 44 components from 32 distinct parts.

Its main chip is the Female SocketS, from the ESP32 family. Other key parts include the TP4056-42-ESOP8 and MT3608. By type, the board carries 22 connectors, 8 resistors, 6 capacitors, 3 ICs, 3 diodes and 1 inductor.

From the project

Welcome to my PCB projects repository! This space is dedicated to documenting my journey in designing, creating, and improving printed circuit boards (PCBs). Here, I share various PCB projects, including schematics, layouts, bill of materials (BOM), and relevant documentation.

Atomic01: common questions

What microcontroller does the Atomic01 use?

The Atomic01 is built around the Female SocketS, from the ESP32 family.

How big is the Atomic01 PCB?

The Atomic01 measures 86.6 × 71 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Atomic01?

44 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the Atomic01 design files?

From the rajeev2705/PROJECTS repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Atomic01 design in my own project?

The repository has no license, so all rights stay with rajeev2705. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Atomic01 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.
