Esp8266controller: common questions
What microcontroller does the Esp8266controller use?
The Esp8266controller is built around the WEMOS_D1_MINI, from the ESP8266 family.
How big is the Esp8266controller PCB?
The Esp8266controller measures 224.2 × 60 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Esp8266controller?
86 components, from 22 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 Esp8266controller design files?
From the pe1mew/lasermaze-game repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Esp8266controller design in my own project?
The repository has no license, so all rights stay with pe1mew. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Esp8266controller 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.
