(2) The basic parameters of this module are all in the details page, and a PDF file of module parameter index data is provided. Schematics and engineering files are not provided. If you have any operational problems, please consult customer service. (3) Before using the module, please read the details page of this module to understand the power supply and usage restrictions, so as to avoid damage to the module due to improper operation. (4) All modules in our shop guarantee to provide real module parameters, functions and pictures, and all modules are tested and shipped. Description: The current meter adopts a high-precision reference + high-precision sampling resistor scheme, which has accurate measurement and high resolution. Using 1 ohm small resistance sampling resistor, the input voltage drop is only 70mV when the input current reaches 70mA, which has minimal impact on the measured system. Using bipolar design, it can measure offerirectional positive and negative currents up to ±70mA, and the current can be measured normally without deliberately distinguishing the wiring. With its own anti-reverse connection circuit, the module will not work when the power supply is reversed, but it will not cause damage to the circuit. With over-current protection circuit, input current up to 1A will not cause damage to the circuit. When the current returns to plus or minus 70mA, the module will immediately measure the current value normally without restarting. The module integrates serial communication function. The current data of the module can be read back by devices such as a single-chip microcomputer, a computer (USB-to-serial module required), etc. The protocol adopts the protocol for Modbus, which is convenient for large-scale integration and industrial applications.
