Hotpot table
About the Hotpot table PCB
Hotpot table is an open source ESP32 PCB design by rahuljeyaraj, published on GitHub under the MIT license. It is a board, with 17 components from 10 distinct parts.
Its main chip is the XIAO ESP32S3, from the ESP32 family. Other key parts include the HX711.

Eight ingredient bins are set into a tabletop of projector screen fabric. A projector hangs above and lights the whole surface; a camera beside it watches your hands. Every name, price, calorie count, tasting note, cart line and the entire checkout is projected light landing on the table itself — right where a person stands with a bowl in one hand and tongs in the other.

Hotpot table: common questions
What microcontroller does the Hotpot table use?
The Hotpot table is built around the XIAO ESP32S3, from the ESP32 family.
How many components are on the Hotpot table?
17 components, from 10 distinct parts. The full bill of materials is listed on this page.
Where can I download the Hotpot table design files?
From the rahuljeyaraj/hotpot-table repository on GitHub, which has the schematic; the links under Design files point to each one.
Can I use the Hotpot table design in my own project?
Yes, under the terms of its MIT license, which rahuljeyaraj chose for the repository.
Can I test firmware for the Hotpot table 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.
