Outline and pin positions checked against the manufacturer datasheet (C55382861 BQ-1209GRBH-M5J rev 01 p3). The sheet labels the four pads GND (top-left), DOUT (top-right), DIN (bottom-left), VDD (bottom-right) but does not number them; the pin numbers here follow the clockwise order of the Chongtian CT-3227 sheet with the same footprint and labels (1 GND, 2 DOUT, 3 VDD, 4 DIN). Pad sizes are copied from that sheet (PCB land here 1.1 x 1.1 mm, 1.6 mm column gap, 0.3 mm row gap). A green dot at the left edge is the only mark. What this means.

Compatibility

  • protocol compatible SK6805

    The window table (T0H 0.2-0.4, T0L >=0.8, T1H 0.7-1.0, T1L >=0.2 us, reset 200 us, 5 mA class, GRB) is the min/typ/max shape of the OPSCO SK6805-EC sheets that the sk6805 protocol records; typical values 0.3 / 0.9 / 0.9 / 0.3 us. The Beking sheets never name SK6805. source ↗

Dating evidence

Nobody announces these parts, so this records what we can actually cite rather than a release date. Library support proves only that the part existed by that date.
