Badapple006sao: common questions
What microcontroller does the Badapple006sao use?
The Badapple006sao is built around the CH32V006F8U7, from the RISC-V family.
How big is the Badapple006sao PCB?
The Badapple006sao measures 16.5 × 16.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Badapple006sao?
23 components, from 12 distinct parts. The full bill of materials is listed on this page.
Where can I download the Badapple006sao design files?
From the cnlohr/badderapple repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Badapple006sao design in my own project?
Yes, under the terms of its MIT license, which cnlohr chose for the repository.
Can I test firmware for the Badapple006sao 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.
