This I2C analog-to-digital converter (ADC) board is designed for use with a standard 4-20mA current loop, making it ideal for connecting to current loop sensors. The board has 4 input channels, each of which can be connected to either a voltage or current source. Here are the key features:
4 channels of analog inputs
Voltage: 0-5V, 0-10V
Current: 0-20mA, 4-20mA, 0-40mA
ADC Resolution: Selectable between 12, 14, 16, and 18 bits, with the most significant bit (MSB) used as a sign bit.
Programmable Gain Amplifier (PGA): Configurable to 1, 2, 4, or 8.
Microcontroller Interface: Communicates via I2C bus, with bus speeds of 100kHz, 400kHz, and 3.4MHz supported.
I2C Addressing: Addresses selected by two jumpers, and the board can be configured with up to 8 different addresses. Multiple boards can be connected on the same bus.
Pull-up Resistors: For I2C lines, can be enabled or disabled via jumpers.
Supply Voltage: Requires a single supply voltage ranging from 2.7V to 5.5V.
This board offers a simple and efficient way to interface with analog sensors via I2C while providing flexible configuration options for your measurement needs.
To prevent damage to the board, do not plug or unplug I2C cables while the power supply is on. Always turn off the power supply before plugging or unplugging I2C cables on the board.
