For 3.3V boards such as ESP32 or Raspberry Pi Pico, use a voltage divider or level shifter to scale the 5V output down. Pairs directly with 4-20mA sensors: pressure transducers, level sensors, and temperature transmitters.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect the sensor's 4-20mA positive wire to I+ and negative to I- on the module. Supply the module with 7-24V DC to VCC and GND. The Vout pin provides 0-5V analog output proportional to the input current—connect it to any Arduino analog input pin. No pull-up resistors needed; the module uses an internal 250Ω sense resistor.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
