Project Title: common questions
What microcontroller does the Project Title use?
The Project Title is built around the AP2112-3.3, from the ESP8266 family.
How big is the Project Title PCB?
The Project Title measures 74.7 × 96.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Project Title?
51 components, from 20 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 Project Title design files?
From the hulkco/oshwi repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Project Title design in my own project?
The repository has no license, so all rights stay with hulkco. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Project Title 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.
