C816SX: common questions

What microcontroller does the C816SX use?

The C816SX is built around the ESP32-C5-WROOM-1, from the ESP32 family.

How big is the C816SX PCB?

The C816SX measures 160 × 101.4 mm, has 6 copper layers and is 0.895 mm thick.

How many components are on the C816SX?

229 components, from 68 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 C816SX design files?

From the rjacobs1969/C816 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 C816SX design in my own project?

The repository has no license, so all rights stay with rjacobs1969. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the C816SX 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.
