This design is not yet tested and was not built yet. Currently there's no firmware yet. I am not able to write the code, so feel free to contribute.
Schematic is pretty well documented, you can find most info you'll need there.
Todo:
Send me a message if you need gerbers for the actual heat plate.

Open DIY Beyblade X launcher RPM meter: ESP32-C3 with IR sensors and an OLED, Bluetooth (Battle Pass protocol), and a browser app for shot data and firmware updates. KiCad hardware, ESP-IDF firmware, 3D-printed case.

It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
82 parts, built around the IP2721, ITR8307/S17/TR8(B), B5819W and DC-005-5A-2.5. 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.
From the DerSpatz/PCB-reflow-solder-table repository on GitHub, at the commit this page was made from: the board is HeatTable-Base-v0.9/HeatTable-Base-v0.9.kicad_pcb and its schematic HeatTable-Base-v0.9/HeatTable-Base-v0.9.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
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).
