ESP32C3 FPGA: common questions

What microcontroller does the ESP32C3 FPGA use?

The ESP32C3 FPGA is built around the ESP32-C3, from the ESP32 family.

How big is the ESP32C3 FPGA PCB?

The ESP32C3 FPGA measures 76.2 × 31.8 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the ESP32C3 FPGA?

85 components, from 42 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32C3 FPGA design files?

From the emeb/ESP32C3_FPGA repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32C3 FPGA design in my own project?

Yes, under the terms of its MIT license, which emeb chose for the repository.

Can I test firmware for the ESP32C3 FPGA 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.
