Lhc esp: common questions
What microcontroller does the Lhc esp use?
The Lhc esp is built around the ESP32-S3-WROOM-1-N16R2, from the ESP32 family.
How big is the Lhc esp PCB?
The Lhc esp measures 48.4 × 35.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Lhc esp?
24 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 Lhc esp design files?
From the lhc/Hardware 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 Lhc esp design in my own project?
The repository has no license, so all rights stay with lhc. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Lhc esp 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.
