3 digit 7-Segment module 2.3 inch Serial Data Display with TM1650 and Arduino Uno MCU

with this new 3 Digit 2.3 inch 7 segments Serial like protocol Display module using TM1650 as a custom 7segment controller  Data save the required IO pins needed to drive all this number of pins and will display large size 7 segment 3 digit numbers. 2.3 Inch height, which can be visible over large distance. 

Features:

• Supply 12V DC For Display
• Inputs data TTL signals just 3 pins (Data,Clock,Strope)
• very easy to control it using Arduino or any other microcontroller(Sample code available or request).
• extra Free GPIO brought on the PCB edge to connect them to Sensors , other hardware or external micrcontroller upon your application needs.
• simple arduino lib to control it with just 1 line of code .

easy control by any micro-controller suitable for you or you can use the builtin ATMEGA328 chip and program it with Arduino IDE. useful circuit to make Timer, stop watch, Score Board, Token No, Vehicle counter at parking and many other applications.

Arduino Sample Code:

/*

  Basic program to test this module just to send the number you need to display via the Serial Monitor in 

  this format 123$ whre 123$ is the number you need to show , and it will blink this number 3 times
