1088AS Datasheet – 8×8 Dot Matrix LED Display

Part Number : 1088AS

Function : 3mm, 8×8 Dot Matrix LED Display

Package : Module Tyoe Pin

Manufacturers : OASIS


1088AS LED 8X8 Matrix

Description :

Each matrix has 128 LEDs (64 Red & 64 Green) however there is noticeably not 256 leads. Instead the LEDs are wired into a matrix. This matrix has the LED’s anodes connected across rows (8 pins) then the red and green LED’s cathodes  attached across columns (8 pins each). To light an LED connect it’s rows anode  to +5volts, and through a resistor, it’s columns cathode to ground. (you can try this without a micro-controller)

1. RoHS: Yes
2. Emitted Colour: Red
3. Face Color: Black
4. Type: Row Cathode Column Anode
5. Wavelength : 625 ~ 630nm
6. Forward Voltage : 2.1V ~ 2.5V
7. Forward Current: 20mA
8. Dimesions: 32mm x 32mm x 8.0mm
