This module is a sensor module used to detect the current, voltage, and power of circuits. It supports I2C interface communication and can be used with other microcontrollers such as Arduino to monitor the current and voltage of robot vehicle motors and other applications.INA219 at -40C to + 1% can be achieved within the maximum error accuracy 85C temperature range, the maximum offset is 100 uV. The high-precision products combine the advantages of 12-bit resolution, as much as possible to help customers reduce the pressure drop on the shunt resistor, thereby minimizing power loss and power consumption and save board space. The device can be sensed bus voltage range of 0 V to +26 V.<\/p>\n

Produktparameter<\/p>\n

Betriebsspannung: DC 3 V\u20135 V<\/p>\n

Communication interface: I2C interface<\/p>\n

Maximum measured voltage: 26V<\/p>\n

Maximum measured current: 3.2A, resolution \u00b1 0.8mA<\/p>\n

Measurement accuracy: 1%<\/p>\n

I2C address:<\/p>\n

The default I2C address is 0x40. If necessary, please change it<\/p>\n

For example, using multiple modules or conflicting with another I2C address.<\/p>\n

It can be changed by short circuiting the A0 and A1 solder pads on the board: the default value for solder pad suspension is 0x40<\/p>\n

A0 pad short circuit: Address 0x41<\/p>\n

A1 pad short circuit: Address 0x44<\/p>\n

A1 and A0 pads short circuited: Address 0x45<\/p>\n

VCC: Connected to the positive pole of a 3V-5V power supply<\/p>\n

GND: An den Minuspol des Netzteils anschlie\u00dfen<\/p>\n

SDA: I2C Serial Data<\/p>\n

SCL: I2C Serial Clock<\/p>\n

Vin -: Connect to the positive terminal of the load<\/p>\n

Vin+: Connect to the positive terminal of the load power supply<\/p>\n

<\/p>\n

Current detection<\/p>\n

The module uses a 0.1 ohm 1% 2W current sensing resistor, which can provide 3.2A current processing capability. Low resistance minimizes voltage drop, and at full rated current, the voltage drop across the current sensing resistor will be 0.32V.<\/p>\n

If you want to change the current measurement range, you can replace the resistor with a smaller or larger value. For example, a 0.01 \u03a9 resistor allows for measuring up to 32A of current with a resolution of 8mA, while a 1 \u03a9 resistor will reduce the measurement range to 320mA with a resolution of 0.08mA<\/p>\n
