About the Pcb openair main

Pcb openair main is an open source ESP32 PCB design by Open-Air-Foundation, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 4.2 × 19 mm, with 36 components from 20 distinct parts.

Its main chip is the ESP32-C3-MINI-1-N4, from the ESP32 family. Other key parts include the TPL5010 and LM1117-3.3. By type, the board carries 13 capacitors, 11 resistors, 3 ICs, 2 diodes, 1 fuse and 1 switch.

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

Pcb openair main: common questions

What microcontroller does the Pcb openair main use?

The Pcb openair main is built around the ESP32-C3-MINI-1-N4, from the ESP32 family.

How big is the Pcb openair main?

The Pcb openair main measures 4.2 × 19 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pcb openair main?

36 components, from 20 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 Pcb openair main design files?

From the Open-Air-Foundation/pcb-openair-main 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 Pcb openair main design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which Open-Air-Foundation chose for the repository.

Can I test firmware for the Pcb openair main 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.
