HD-D35 specifications and replacement options
The Huidu HD-D35 is no longer in production. The existing product recommendation is to consider HD-D16 or HD-D36. Compare control range, module interfaces and communication options before selecting a replacement.
D35 is an asynchronous controller for full-color strip displays, including shopfront lintels, taxi-roof signs and bus advertising screens. It uses an ARM A9 CPU with hardware video decoding and supports management from a PC, mobile app or cloud platform.

Playback and status checks
The D35 supports video and animation, editable text with pictures, clocks, neon effects and counting functions. Temperature/humidity display and adaptive brightness are also listed in the specification. The stated program duration is more than four hours with 4 GB memory; content size affects actual duration, and USB storage can expand capacity.
During normal operation, the RJ45 orange light stays on and its green light flashes. The Display indicator flashes, D1 is the flashing running indicator and D2 is the steady power indicator. A test button checks display brightness and contrast. The GPS connection supports time correction and positioning.
