LED bar module with 8 common cathode LEDs with integrated resistors, compatible with Arduino and other development boards, designed for visual display and quick testing of digital outputs.
The module allows individual control for each LED through a logic signal, active low level operation, direct use at 3 and 5V without external resistors, low current consumption and easy identification of channels through LEDs in different colors.
Thanks to the integrated resistors, the module can be connected directly to the digital outputs of the development board, making it ideal for debugging, status indicators, microcontroller experiments and DIY bar graph projects.
Specifications:
Supply voltage: 3-5.5VDC
Number of LEDs: 8
LED type: common cathode
Current limiting resistors: integrated
Maximum current: < 24 mA
Active level: LOW
Dimensions: 23 x 15 mm
LED color:
| LED channel | LED color |
|---|---|
| D0 | Yellow-green |
| D1 | Yellow-green |
| D2 | Blue |
