4*8 LED matrix module for micro:bit

Specifications

• Input voltage: DC 5-9V

• Total number of LEDs: 32

• Brightness: R: 400-500MCD; G: 1000-1500MCD; B: 300-400MCD

• Headband: R: 620-625 NM; G: 520-522.5 NM; B: 467.5-470 NM

• Intelligent reverse connection protection

• SK6812IC control circuit shares a common power supply with the LED light source

• The control circuit and RGB chip are integrated into a 5050 package component, forming a complete external control pixel

• Integrated signal shaping circuit

• Integrated power-on reset and power-off reset circuitry

• Serial cascade interface: Capable of completing data reception and decoding via a signal line.

• Any two-point transmission distance does not need to add circuitry when the distance does not exceed 5 meters

• When the refresh rate is 30 frames/second, the number of cascades is not less than 1024 points

• Data transmission speed can reach up to 800 Kbps

• Minimum scanning frequency: 400Hz/s
