ESP32 CP2102: common questions

What microcontroller does the ESP32 CP2102 use?

The ESP32 CP2102 is built around the ESP32-WROOM-E, from the ESP32 family.

How big is the ESP32 CP2102 PCB?

The ESP32 CP2102 measures 30.5 × 48.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32 CP2102?

32 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32 CP2102 design files?

From the jenschr/ESP32-workshop-files repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32 CP2102 design in my own project?

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

Can I test firmware for the ESP32 CP2102 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.
