TM1637 Displays

"TM1637" is used to identify a 7-segment Display and Keyboard scanning IC

"TM1637" is also used to identify display/keypad modules using this part

Features:
20-pin surface mount part
6 character - 7-segment display
8 brightness levels
16 button keypad (2x8 matrix)
Built-in oscillator
2-wire I2C like control signals, CLK, DIO

When purchasing a four character display, it will either support a ':' to be used as a clock
OR, each character will have decimal point support.
This is a function of the module, not the IC.

Notes:

Although the 2-wire interface appears to be "I2C like", it is NOT I2C.
The module does not have or supports an I2C address.
