README
README.mdDrishtikon:
EdgeAI based human detection system
- The beginnings: Drishtikon is a framework consisting of two modules, the mainboard and the controller modules that can be powered directly from the 220VAC mains in dorms, libraries and canteens. The two boards communicate with each other using a BLE protocol and the mainboard is connected to the internet via Wi-Fi, it connects to the local network using hard coding.

Questions
How big is the Controller PCB?
It measures 56 × 36 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Controller use?
44 parts, built around the ESP32-S3-WROOM-1-N8, D3V3XA4B10LP, TLV75801PDBV and 1N5819HW-7-F-01. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Controller KiCad files?
From the Debanx3/Drishtikon repository on GitHub, at the commit this page was made from: the board is Controller/Controller.kicad_pcb and its schematic Controller/Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
