GD32WavePlayer: common questions
What microcontroller does the GD32WavePlayer use?
The GD32WavePlayer is built around the GD32, from the GD32 family.
How big is the GD32WavePlayer PCB?
The GD32WavePlayer measures 50 × 54 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the GD32WavePlayer?
31 components, from 20 distinct parts. The full bill of materials is listed on this page.
Where can I download the GD32WavePlayer design files?
From the JennyDigital/GD32WavePlayer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the GD32WavePlayer design in my own project?
The repository has no license, so all rights stay with JennyDigital. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the GD32WavePlayer without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug GD32 firmware against it before you order a PCB.
