Source note

Compiled from the official specification HD-R5S V1.1. The document contradicts itself on capacity: the overview says a single card supports control of 256*512 pixels, the parameter table recommends 98,304 pixels (128*768); the lower, recommended figure is recorded as the loading rectangle and both statements are kept in the specifications. No separate figures for conventional and PWM driver ICs are printed. Input voltage is printed as 4V-6V in the parameter table and as rated voltage DC 4.2V-5.5V in the technical parameters; the narrower range is recorded. The parameter table states the power as 5W. The dimensions are read from the dimension drawing, which prints no unit.
