TX
|
Transmit - This pin is used in serial communication to send data to another device.
|
|
4
|
RX
|
Receive - This pin is used in serial communication to receive data from another device.
|
|
5
|
SCL
|
Serial Clock - In the I²C communication protocol, this is the clock signal line used to synchronize data transmission.
|
|
6
|
SDA
|
Serial Data - In the I²C communication protocol, this is the line used for data transmission.
|
|
Note: Typically, VCC and GND are used for power supply, TX and RX are used for serial communication, while SCL and SDA are used for I²C communication. These interfaces allow the receiver to exchange power supply and data with external devices.
