Esp8266: common questions
What microcontroller does the Esp8266 use?
The Esp8266 is built around the ESP-12E, from the ESP8266 family.
How big is the Esp8266 PCB?
The Esp8266 measures 85 × 75 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Esp8266?
47 components, from 28 distinct parts. The full bill of materials is listed on this page.
Where can I download the Esp8266 design files?
From the Hackuarium/esp-12e repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Esp8266 design in my own project?
The repository has no license, so all rights stay with Hackuarium. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Esp8266 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.
