4 in 1 Dot Matrix MCU LED Display Modules DIY Set with 16 Channel PWM/Servo Driver IIC Interface-PCA9685 Module
Reviews & Ratings
It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good for when you want to control white or blue LEDs with 3.4+ forward voltages)
6 address select pins so you can wire up to 62 of these on a single i2c bus, a total of 992 outputs
Adjustable frequency PWM up to about 1.6 KHz;Configurable push-pull or open-drain outputManufacturer
12-bit resolution for each output - for servos, that means about 4us resolution at 60Hz update rate
colour: blue+Red
Material: plastic+PCB
MCU LED Display Modules :
There is a built-in serial input / output common cathode display driver.
Can be connected to the miniprocessor and 7-segment digital LED display von eight digits.
Also can be connected to the bar graph or 64 independent LED.
Includes Type B BCD encoder, multiple scanning circuit and segment driver.
A static RAM (8 x 8) is used to store data.
Multifunctional and practical.
A comfortable 4-wire interface can be connected to all general miniprocessor
Only 3 IO interfaces will be used to drive a dot matrix display
Operating voltage: 5V
screw opening hole: 3mm
cable length: 20cm
item size: 12.8 x 3.2 x 1.5 cm / 5 x 1.3 x 0.6in
PWM Servo Motor Driver I2C Module :
An I2C-controlled PWM driver with a built in clock. That means that, unlike the TLC5940 family, you do not need to continuously send it signal tying up your microcontroller, its completely free running!
Output enable pin to quickly disable all the outputs
Terminal block for power input (or you can use the 0.1 inch breakouts on the side)
Reverse polarity protection on the terminal block input
"Chain-able" design
size: 60 x 25mm
