WifiWallSwitch: common questions
What microcontroller does the WifiWallSwitch use?
The WifiWallSwitch is built around the ESP32-S3-WROOM-1-N8, from the ESP32 family.
How big is the WifiWallSwitch PCB?
The WifiWallSwitch measures 65.4 × 68 mm, has 2 copper layers and is 0.57 mm thick.
How many components are on the WifiWallSwitch?
141 components, from 61 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 WifiWallSwitch design files?
From the Uspizig/WifiWallSwitch 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 WifiWallSwitch design in my own project?
Yes, under the terms of its GPL-3.0 license, which Uspizig chose for the repository.
Can I test firmware for the WifiWallSwitch without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
