he P3H UART2 is a compact LCD display used on electric bicycles to show basic ride and system information such as speed and mileage. It mounts directly to the handlebars and connects to compatible e-bike controllers using a UART communication protocol. This display is typically used as a replacement for a damaged screen or when restoring functionality on e-bikes that already use a UART-based control system. Key Features• LCD screen for speed and mileage display• Compact, handlebar-mounted design• Digital readout optimized for clear visibility while riding• Designed for electric bicycle control systems• Lightweight and low-profile housing Compatibility & Use Notes• Designed for e-bike systems using UART communication• Commonly paired with compatible controllers that support P3H / UART2 displays• Handlebar mounting hardware typically included depending on supplier• Connector type and pin layout must match the controller• Not compatible with CAN-bus display systems• Not universal—controller compatibility must be verified before installation Service / Ownership ContextE-bike displays are controller-specific. Before installation, confirm protocol (UART vs CAN), connector style, and voltage compatibility. After install, system functions such as speed reading and power levels should be verified during a test ride. Fit & Use Signals• Good fit if your e-bike uses a compatible UART-based controller• Good fit for replacing a damaged or non-functional LCD display• Good fit for basic speed and mileage tracking• Not a fit for CAN-bus systems• Not a fit if connector or protocol does not match your controller
