This is a very inexpensive and adaptable device that may be used for a variety of purposes. The devices contain a 150A low-power shutdown mode, 8 channel brightness control, a scan-limit register that allows the user to display from 1 to 8 digits, and a test mode that forces all LEDs on.
Although the datasheet indicates that it uses an I2C interface, this IC can be driven without one, and it is recommended that you do so because this IC does not provide any I2C addresses, which means you cannot drive more than one I2C device on the I2C bus. A basic schematic of the TM1650 with a keypad is shown below.
TM1650 Schematic
As you can see, this gadget is designed to be controlled using a matrix keypad to operate the TM1650 IC. Aside from that, you may control the TMS1650 IC with an Arduino by using the TM16XX library by maxing-rd from GitHub. This library allows you to control the TMS1650 IC with any Arduino pin.
