AIO: common questions
What microcontroller does the AIO use?
The AIO is built around the LQFP-100_14x14mm_P0.5mm, from the RISC-V family.
How big is the AIO PCB?
The AIO measures 63.1 × 63.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the AIO?
155 components, from 35 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 AIO design files?
From the ErBWs/CH32-Bike-Overland 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 AIO design in my own project?
Yes, under the terms of its GPL-3.0 license, which ErBWs chose for the repository.
Can I test firmware for the AIO 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.
