Circuit final design: common questions
What microcontroller does the Circuit final design use?
The Circuit final design is built around the ESP-12E, from the ESP8266 family.
How big is the Circuit final design PCB?
The Circuit final design measures 90.9 × 52.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Circuit final design?
21 components, from 17 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 Circuit final design design files?
From the ambadran/Free-Lance-Projects repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Circuit final design design in my own project?
The repository has no license, so all rights stay with ambadran. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Circuit final design 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.
