About the BirdNest PCB

BirdNest is an open source ESP32 PCB design by VorosEgyes, published on GitHub under the MIT license. It is a 2-layer board measuring 100 × 100 mm, with 42 components from 27 distinct parts.

Its main chip is the ESP32-CAM, from the ESP32 family. Other key parts include the DS18B20, TP4056_Module, ME2188, LM393 and TL431DBZ. By type, the board carries 14 resistors, 12 capacitors, 6 ICs, 3 transistors, 2 connectors and 2 diodes.

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

From the project

BirdNest Camera

BirdNest is a battery-aware ESP32-CAM wildlife and bird nest monitoring project built with PlatformIO and Arduino. It captures photos on schedule or command, sends images and status updates to Telegram, and supports MQTT telemetry for smart home and IoT integrations. The firmware includes deep sleep power saving, OTA remote updates, WiFi recovery logic, DS18B20 temperature monitoring, and calibrated battery voltage reporting for reliable long-term outdoor operation.

BirdNest: common questions

What microcontroller does the BirdNest use?

The BirdNest is built around the ESP32-CAM, from the ESP32 family.

How big is the BirdNest PCB?

The BirdNest measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BirdNest?

42 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the BirdNest design files?

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

Can I use the BirdNest design in my own project?

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

Can I test firmware for the BirdNest 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.
