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 Context
E-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
