SIAECOSYS DKD TFT
SIAECOSYS DKD TFT is the color-screen upgrade to the DKD LCD speedometer. Retains the familiar DKD brand and dashboard layout but replaces the monochrome LCD with a color TFT for richer readouts — voltage, speed, power, gear (1/2/3/S/R/P/N), and fault codes in a polished interface. Switchable to night mode. Designed for VOTOL controllers (per OEM product page); dual-protocol firmware: supports both SIAECOSYS ONE-LIN and CAN BUS communication, selectable to match the paired VOTOL / Fardriver controller. ⚠️ **Power-supply warning:** the black (+12V) wire is an auxiliary supply input — same architecture as the DKD LCD. It must be fed from a 12V DC-DC converter or a 12V BMS aux output, NOT pack B+. Connecting to pack voltage will destroy the display. Display housing uses a 20-pin Molex Mini-Fit Jr 2×10 connector that plugs into the bundled display harness, which breaks out to a single 9-pin Mini-Fit Jr carrying CAN_L/CAN_H, ONE_WIRE_COMM, +12V, GND, turn signals, and high beam — simpler than the DKD LCD's Y-split harness (separate CAN and Vehicle ends). 500g.
In brief: E-bike display. Protocols: SiAECOSYS ONE-LIN, SiAECOSYS CAN BUS.
