LHCbit: common questions

What microcontroller does the LHCbit use?

The LHCbit is built around the ESP32-S3-WROOM-1-N16R2, from the ESP32 family.

How big is the LHCbit PCB?

The LHCbit measures 51.6 × 44.4 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the LHCbit?

51 components, from 26 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 LHCbit 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 LHCbit 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 LHCbit 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.
