Cjmcu Modulo Controlador Matriz De Led 16x8 Ht16k33 Driver Itytarg

Description:

This is the magic sauce in the 7-segment and matrix backpacks, now available in breadboard-friendly breakout board format. The HT16K33 is a neat little chip that has the ability to drive a multiplexed 16x8 matrix (that's 128 individual LEDs). The communication protocol is I2C so it uses only 2 pins, and you can have up to 8 selectable I2C addresses so that's a total of 8 matrices, each one controlling 16x8 LEDs for 1024 total LEDs. 

This module break out all 16 anodes and 8 cathodes as well as the I2C and power pins. You'll need to wire up the anodes and cathodes by checking out your matrix datasheet and lining up the pins. Wire up any matrix you want and use our handy library to write to the display however you wish. Note that the driver can turn LEDs on and off but does not have the ability to individually PWM dim them. This chip is rock solid, has Arduino & Pi example code written for it and is easy to use.

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 13*3 (MAX.) matrix key scan circuit. The software configuration features of the HT16K33 makes 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.

Features:

• Operating voltage: 4.5V~5.5V
• Integrated RC oscillator
• I2C-bus interface
• 16*8 bits RAM for display data storage
• Max. 16 x 8 patterns, 16 segments and 8 commons
• R/W address auto increment
• Max. 13 x 3 matrix key scanning
• 16-step dimming circuit
• Selection of 20/24/28-pin SOP package types

Applications:

• Industrial control indicators
• Digital clocks, thermometers, counters, multimeters
• Combo sets
• VCR sets
• Instrumentation readouts
• Other consumer applications
• LED Displays

CJMCU- HT16K33 dot matrix LED control drive module digital tube driver development board
The CJMCU-K33 is a storage image and a 16x8 LED controller driver with a maximum display segment of 16x8 and a 133 array scan circuit with an operating voltage of 4.5V to 5.5V.
