Gateway: common questions
What microcontroller does the Gateway use?
The Gateway is built around the STM8L151K4T6, from the STM32 family.
How big is the Gateway PCB?
The Gateway measures 100 × 45 mm, has 2 copper layers and is 1.69 mm thick.
How many components are on the Gateway?
73 components, from 47 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 Gateway design files?
From the npeixoto64/ExitGuardian 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 Gateway design in my own project?
The repository has no license, so all rights stay with npeixoto64. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Gateway without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
