README
README.mdtime2time
Chronometer with partials measurement for the line-following competitions.
Characteristics:
- ESP32 module (STM microcontroller + Bluetooth + Wifi)
- Industrial distance sensor for robots pass-through detection
- Lipo 1S battery
- USB Lipo battery charge management
- I2C OLED display port
- Buzzer for robots pass-through signaling
- RGB led for chronometer status signaling
- Firmware upload via USB
- Address selection to synchronize several modules
- Expansion port for future improvements
This project has been motivated because of the limitations that the last chronometer had. The main purpose is to communicate the system with the PC of the competition organization and facilitate the taking and visualization of the times.

Questions
How big is the Time2time PCB?
It measures 50 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Time2time use?
97 parts, built around the CP2102N-A01-GQFN28R, ESP32-WROOM-32, LMR62421XMF and TPS63001DRC. 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 Time2time KiCad files?
From the Resaj/time2time repository on GitHub, at the commit this page was made from: the board is hw/Kicad/time2time.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Time2time design in my own project?
Its repository states no licence, so its author keeps all rights: ask Resaj before reusing the design.
