Aqp moda KBD: common questions

What microcontroller does the Aqp moda KBD use?

The Aqp moda KBD is built around the C2913203, from the ESP32 family.

How big is the Aqp moda KBD PCB?

The Aqp moda KBD measures 141 × 89.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Aqp moda KBD?

181 components, from 63 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 Aqp moda KBD design files?

From the aquarius-plus/aquarius-plus-pcbs 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 Aqp moda KBD design in my own project?

Yes, under the terms of its MIT license, which aquarius-plus chose for the repository.

Can I test firmware for the Aqp moda KBD 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.
