lamaPLC: TM1637 7-segment display
The TM1637 module or chip is a driver for 4-digit 7-segment display modules. These chips are standard in inexpensive display units. They communicate with the processor using an I²C-like protocol. The implementation relies entirely on software emulation and does not utilize any specialized hardware, except for GPIO pins. It is assumed that pull-up resistors are present, typically integrated into the display module.
- Operating voltage: 3.3 – 5 V DC
- Maximum current draw: 80mA
- Reverse polarity protection: Yes
