App audio: common questions
What microcontroller does the App audio use?
The App audio is built around the ESP-12F, from the ESP8266 family.
How big is the App audio PCB?
The App audio measures 57 × 33 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the App audio?
24 components, from 13 distinct parts. The full bill of materials is listed on this page.
Where can I download the App audio design files?
From the zyyan20h/PCBRenewal repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the App audio design in my own project?
The repository has no license, so all rights stay with zyyan20h. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the App audio without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
