product description

  • ST7540Development board new board, useST7540 + STM8Structure, small size, is the smallest carrier on the market communication module.
  • With this module, the user can easily220VACor350VDCCarrier communication is carried out in the following environments, and empty wires that are not energized are also available.
  • After the new board, the module in the anti-jamming capability, job stability, module size, ease of use has been improved.
  • Is currently on the market the same kind of modulation under the most stable and reliable module.
  • ST7540Chip usedFSKModulation mode, half-duplex communication, line maximum communication rate4800BPS, Is widely used, the reference design of the largest line communication chip.
  • This module is based onST7540Chip toSTM8Single-chip control, to achieve a complete serial transmission function.
  • While the program download interface,ADInterface leads to user debugging and secondary development.
  • After the purchase confirmed receipt and praise you can receive the schematic,PCBMapPdfVersion), other reference material spree. This module is the best choice for rapid product development.
  • OUR also has a small module supporting the sale of modules, can be directly connected with the module to use, after the connection module without external DC supply to work. The module links as follows:
