Gate controller: common questions
What microcontroller does the Gate controller use?
The Gate controller is built around the ESP-12F, from the ESP8266 family.
How big is the Gate controller PCB?
The Gate controller measures 45.5 × 33 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Gate controller?
21 components, from 14 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 Gate controller design files?
From the eranknafo2001/gate_controller 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 Gate controller design in my own project?
The repository has no license, so all rights stay with eranknafo2001. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Gate controller 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.
