Stargate: common questions
What microcontroller does the Stargate use?
The Stargate is built around the ESP-12F, from the ESP8266 family.
How big is the Stargate PCB?
The Stargate measures 335 × 218.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Stargate?
274 components, from 180 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 Stargate design files?
From the leomanes/stargate 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 Stargate design in my own project?
Yes, under the terms of its GPL-3.0 license, which leomanes chose for the repository.
Can I test firmware for the Stargate 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.
