Lilygo: common questions
What microcontroller does the Lilygo use?
The Lilygo is built around the ESP32-WROOM-32D-N4, from the ESP32 family.
How big is the Lilygo PCB?
The Lilygo measures 77.9 × 81.6 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Lilygo?
147 components, from 81 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 Lilygo design files?
From the Ndambia/lilygo 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 Lilygo design in my own project?
The repository has no license, so all rights stay with Ndambia. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Lilygo 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.
