ME-ESP8266: common questions
What microcontroller does the ME-ESP8266 use?
The ME-ESP8266 is built around the ESP8266EX, from the ESP8266 family.
How big is the ME-ESP8266 PCB?
The ME-ESP8266 measures 66.8 × 34 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ME-ESP8266?
73 components, from 37 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 ME-ESP8266 design files?
From the MaloufSleep/ME-ESP8266 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the ME-ESP8266 design in my own project?
Yes, under the terms of its MIT license, which MaloufSleep chose for the repository.
Can I test firmware for the ME-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.
