KuKirin G2 Master: decoding the display-controller UART protocol

KuKirin G2 Master UART protocol documents the single-wire link between the display and Lenzod controller of a late-2025 Version C scooter. It identifies inverted 230400-baud signalling, 66 66 frame headers, CRC-16/MODBUS and fields for controls, speed and battery voltage. Python tools decode logic-analyser captures and display live values.

Requirements & limits

Prerequisites: Python 3 runs the analysis scripts; capture requires a logic analyser, and the live dashboard requires sigrok-cli.
Scope: The documented protocol applies to the late-2025 KuKirin G2 Master Version C with Lenzod electronics.
Limits: The author measured one scooter; the left brake sensor, some error codes and two field meanings remain unresolved.
