Aqp moda XBus: common questions
What microcontroller does the Aqp moda XBus use?
The Aqp moda XBus is built around the C2913203, from the ESP32 family.
How big is the Aqp moda XBus PCB?
The Aqp moda XBus measures 141 × 89.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Aqp moda XBus?
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 XBus 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 XBus 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 XBus 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.
