P3H UART2 LCD E-Bike Display Computer

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
