App boy: common questions

What microcontroller does the App boy use?

The App boy is built around the ESP-12F, from the ESP8266 family.

How big is the App boy PCB?

The App boy measures 74.5 × 33 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the App boy?

32 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the App boy 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 boy 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 boy 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.
