Electra-100x100mm-2x1-panel: common questions
What microcontroller does the Electra-100x100mm-2x1-panel use?
The Electra-100x100mm-2x1-panel is built around the ESP-12F, from the ESP8266 family.
How big is the Electra-100x100mm-2x1-panel PCB?
The Electra-100x100mm-2x1-panel measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Electra-100x100mm-2x1-panel?
59 components, from 40 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 Electra-100x100mm-2x1-panel design files?
From the Grehasopt/Electra-pcb repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Electra-100x100mm-2x1-panel design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which Grehasopt chose for the repository.
Can I test firmware for the Electra-100x100mm-2x1-panel 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.
