Esp12E-F: common questions
What microcontroller does the Esp12E-F use?
The Esp12E-F is built around the ESP-12F, from the ESP8266 family.
How big is the Esp12E-F PCB?
The Esp12E-F measures 43.3 × 26.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Esp12E-F?
28 components, from 15 distinct parts. The full bill of materials is listed on this page.
Where can I download the Esp12E-F design files?
From the pavankalyan226/Esp12E-F repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Esp12E-F design in my own project?
The repository has no license, so all rights stay with pavankalyan226. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Esp12E-F 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.
