Feature

●♥AC energy metering module: It is an ultra-high-precision fully-isolated multi-functional AC power and energy transmitter. It can collect AC current, voltage, instantaneous power, accumulated power, power factor, and AC frequency to realize full data detection of power quality. Connectable screen module: SUI-101A electric energy metering module supports screen expansion interface and can be connected to 2.2-inch TFT color screen, which is convenient and intuitive to display data.
●♥ Ultra-high-precision fully-isolated multi-functional AC power and electricity transmitter: The product adopts a fully-isolated acquisition scheme to achieve complete isolation of high and low voltage, which greatly enhances safety and reliability. The data can be directly read by using the general Modbus slave protocol, or it can be read through the TTL interface of the microcontroller or connected to the computer via USB to TTL to realize the upper computer detection.
●Interface description: The transmitter isolates the measurement power supply and working power supply through a transformer. The transmitter must be powered by a 5V DC power supply, and the maximum cannot exceed 5.2V. Accumulated battery reset button A button can be welded for battery reset (long press for 10 seconds). The 2.2-inch color screen interface can be connected to a full-color screen, which can display current and voltage RMS, active power, power factor, frequency, and other parameters
●♥Function introduction: The 10-port table corresponding to each peripheral is printed on the back of the development board, and you can also quickly understand the corresponding relationship between the peripheral and the 10-port. Such as: USART1 TX is PA9 RX is PA10, etc.
●♥ Communication method: The communication interface adopts 3.3V TTL asynchronous serial interface, and is compatible with 5V TTL interface. Support self-defined simple protocol and Modbus dual-protocol automatic identification, and automatic output. Baud rate: 6 kinds of baud rates are supported, 1:4800, 2:9600 (default), 3:19200, 4:38400, 5:57600, 6:115200
