Joker60 mkII: common questions

What microcontroller does the Joker60 mkII use?

The Joker60 mkII is built around the ESP32-WROOM-32U, from the ESP32 family.

How big is the Joker60 mkII PCB?

The Joker60 mkII measures 323.5 × 102.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Joker60 mkII?

193 components, from 32 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 Joker60 mkII design files?

From the ZeshuLiu/esp32_keyboard 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 Joker60 mkII design in my own project?

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

Can I test firmware for the Joker60 mkII 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.
