Deep Dive into the HW-133-V1.0 Datasheet: The Go-To RGB LED Ring

The board is straightforward, with two input pins and two output pins, clearly marked on the PCB. : Positive Input Voltage (4.5V - 28V) IN- : Negative Input/Ground (0V) OUT+ : Positive Output Voltage (0.8V - 20V) OUT- : Negative Output/Ground (0V) How to Use the HW-133 Module Preparation : Connect your power source to IN+ and IN- . Measurement : Connect a multimeter to OUT+ and OUT- . hw-133-v1.0 datasheet

Note: Some revisions include a "DO" (Data Out) pad to daisy-chain multiple rings. Deep Dive into the HW-133-V1

If you are working on an Arduino, ESP32, or Raspberry Pi project that requires smooth, addressable RGB lighting, you have likely come across the HW-133-V1.0 . This compact PCB hosts a circular array of WS2812B LEDs. While the board is incredibly popular, finding a consolidated "datasheet" for the board itself (not just the chips) can be tricky. Here is everything you need to know. Note: Some revisions include a "DO" (Data Out)

According to the WS2812B datasheet applied to this board:
