Esp32-dongle v0-1-ceramic antenna: common questions

What microcontroller does the Esp32-dongle v0-1-ceramic antenna use?

The Esp32-dongle v0-1-ceramic antenna is built around the ESP32-C3FH4, from the ESP32 family.

How big is the Esp32-dongle v0-1-ceramic antenna PCB?

The Esp32-dongle v0-1-ceramic antenna measures 11 × 50.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Esp32-dongle v0-1-ceramic antenna?

47 components, from 31 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 Esp32-dongle v0-1-ceramic antenna design files?

From the manhoosbilli1/esp32-dongle-v0-1-ceramic-antenna 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 Esp32-dongle v0-1-ceramic antenna design in my own project?

The repository has no license, so all rights stay with manhoosbilli1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esp32-dongle v0-1-ceramic antenna 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.
