MIKROE-6644

MIKROE-6644 is a Current Sens Click compact add-on board for precise AC, DC, and pulsed current measurement with galvanic isolation. This board features the LES 25-NP current transducer from LEM USA, a closed-loop, multi-range sensor designed for accurate current detection up to 25A. The board offers selectable analogue or digital output via SPI using the MCP3201 12-bit ADC, with a stable 2.5V reference provided by the MCP1525. A jumper-configurable section allows adjustment of the nominal primary current with support for three connection configurations to enhance resolution. It supports both 3.3V and 5V logic levels and includes an onboard switch for easy output selection. Ideal for industrial applications, it fits seamlessly into systems such as motor drives, UPS units, SMPS, battery-powered devices, welding equipment, and solar inverters.
