From the project
An ESP32-S3 hosts a web page over WiFi; the Open control energizes a latching solenoid in a padlock body. The page also reports accelerometer and GPS readings.

Wireslesslock: common questions
What microcontroller does the Wireslesslock use?
The Wireslesslock is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Wireslesslock PCB?
The Wireslesslock measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Wireslesslock?
67 components, from 45 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 Wireslesslock design files?
From the Shehroz30/wireslesslock 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 Wireslesslock design in my own project?
Yes, under the terms of its MIT license, which Shehroz30 chose for the repository.
Can I test firmware for the Wireslesslock 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.
