Firmware Overview:
Current version of Firmware is underdevelopment as it has not be implemeted in real life. This car and controller uses C++ firmware and Arduino IDE for Flashing.
Assembly Instructions :
- Flash Firmware in XIAO ESP32 and Wroom Dev-board
- Solder Motors, Devboard, Battery of car
- Solder Gyro-sensor, Flex-Sensor, Battery of controller
- Check If Everything Works or not, also update the code depending on soldered pins
- Glue togetther the controller enclosure and bracelet. Also Glue together battery and all circuits on Rowwy's base plate
- Screw motor holder to base plate and enjoy the ride.

Questions
How big is the Rowwy PCB?
It measures 66.6 × 32.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rowwy use?
42 parts. 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 Rowwy KiCad files?
From the devisunofficial/Rowwy repository on GitHub, at the commit this page was made from: the board is Rowwy/Rowwy.kicad_pcb and its schematic Rowwy/Rowwy.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rowwy design in my own project?
Its repository states no licence, so its author keeps all rights: ask devisunofficial before reusing the design.
