ESP32 K210: common questions

What microcontroller does the ESP32 K210 use?

The ESP32 K210 is built around the K210, from the RISC-V family.

How big is the ESP32 K210 PCB?

The ESP32 K210 measures 68.8 × 53.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP32 K210?

87 components, from 40 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32 K210 design files?

From the ATmega8/kiterf repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ESP32 K210 design in my own project?

Yes, under the terms of its MIT license, which ATmega8 chose for the repository.

Can I test firmware for the ESP32 K210 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
