0.56 inch 4-bit 7 segment LED I2C driver HT16K33 จอ LED 4 หลัก 0.56 นิ้ว ไดรเวอร์ HT16K33 สำหรับ Arduino

The 7-segment FeatherWing backpack makes it really easy to add a 4-digit numeric display with decimal points and even 'second colon dots' for making a clock.

The LEDs themselves do not connect to the Feather. Instead, a matrix driver chip (HT16K33) does the multiplexing for you. The Feather simply sends i2c commands to the chip to tell it what LEDs to light up and it is handled for you. This takes a lot of the work and pin-requirements off the Feather. Since it uses only I2C for control, it works with any Feather and can share the I2C pins for other sensors or displays.

The product kit comes with:

• A fully tested and assembled Adafruit 4-Digit 7-Segment LED Matrix Display FeatherWing
• Ultra-bright 4-digit 0.56" tall green seven-segment display
• Two 16-pin headers

Features:

- These 7-segment displays normally require 13 pins (5 characters and 8 total segments each).
- Solves the annoyance of using 13 pins or a bunch of chips by having an I2C constant-current matrix controller sit neatly on the back of the PCB.
- The controller chip takes care of everything, drawing all the LEDs in the background.
- All you have to do is write data to it using the 2-pin I2C interface.
- There are three address select pins so you can select one of 8 addresses to control up to 8 of these on a single 2-pin I2C bus (as well as whatever other I2C chips or sensors you like).
- The driver chip can din the entire display from 1/16 brightness up to full brightness in 1/16th steps.
- It can't din individual LEDs, only the entire display at once.
- Size: 5.03 x 2.68 x 1.2 cm/2 x 1.1 x 0.5 inch
