About the TreeLights PCB

TreeLights is an open source ESP32 PCB design by Pegoku, published on GitHub. It is a 2-layer board measuring 80 × 124 mm, with 26 components from 8 distinct parts.

Its main chip is the ESP-WROOM-32E, from the ESP32 family. Other key parts include the AZ1117H-3.3TRG1 and AMS1117-5.0_C347223. By type, the board carries 10 capacitors, 9 LEDs, 3 ICs, 2 battery holders, 1 connector and 1 resistor.

TreeLights: common questions

What microcontroller does the TreeLights use?

The TreeLights is built around the ESP-WROOM-32E, from the ESP32 family.

How big is the TreeLights PCB?

The TreeLights measures 80 × 124 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TreeLights?

26 components, from 8 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 TreeLights design files?

From the Pegoku/ClassPCBs 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 TreeLights design in my own project?

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

Can I test firmware for the TreeLights 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.
