Power line carrier module communication st7540 development board Dc/power off/three phase available super small | Инструменты

Power line carrier module

Using the power line to transmit signals for communication, without additional wiring, free from the influence of the space environment, communication distance.

ST7540 development board is a new board, ST7540+STM8 structure, the volume is very small, is the smallest carrier communication module on the market. With this module, users can conveniently carry out carrier communication in the environment below 220VAC or 350VDC. The serial port baud rate, carrier baud rate and carrier frequency can be configured. After the new board, the module in the anti-interference ability, work stability, module volume, the use of convenience has been comprehensively improved. It is the most stable and reliable module in the same modulation mode.

ST7540 chip adopts FSK modulation mode, half-duplex communication, the highest communication rate of power line is 4800BPS, it is the power line communication chip widely used and with the most reference design. This module is based on ST7540 chip and controlled by STM8 microcontroller to achieve complete serial port pass-through function. At the same time, the program download interface, AD interface for user debugging and secondary development. After purchase, confirm receipt and praise, you can get the information package of schematic diagram and PCB diagram (PDF version), which is the best choice for rapid product development.
