Bird3: common questions

What microcontroller does the Bird3 use?

The Bird3 is built around the ESP32-S3-WROOM-1-N8R8, from the ESP32 family.

How big is the Bird3 PCB?

The Bird3 measures 43 × 108 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bird3?

61 components, from 46 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 Bird3 design files?

From the ysoyjcgoxohxoh/Bird3 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 Bird3 design in my own project?

Yes, under the terms of its MIT license, which ysoyjcgoxohxoh chose for the repository.

Can I test firmware for the Bird3 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.
