• 24x16 LED matrix with colours: Red, Green, Blue, and White
• Python demo software
  
• HT16K33 for the LED matrix controller chip
• The HT16K33 is a memory mapping and multi-function LED controller driver. The max display segment numbers in the device is 128 patterns (16 segments and 8 commons) with a 13x3 (MAX.) matrix key scan circuit. The software configuration features of the HT16K33 make it suitable for multiple LED applications including LED modules and display subsystems. The HT16K33 is compatible with most microcontrollers and communicates via a two-line bidirectional I2C bus.

Technical specifications:

• Operating voltage: 4.5V~5.5V
• Integrated RC oscillator
• I2C-bus interface
• 16x8 bits RAM for display data storage
• Maximum of 16x8 patterns, 16 segments and 8 commons
• R/W address auto increment
• Maximum of 13 x 3 matrix key scanning
• 16-step dimming circuit
• Selection of 20/24/28-pin SOP package types
• i2c address 70, 71 for two LED drivers: HT16K33
• DataSheet
• Python Test Program:
• 16x16Matrix GHAT software pack
