Gravity: 0-10V 15-bit High-Precision Dual-Channel ADC Module

Jargon buster

Plain-language definitions for the technical terms used above.

ADC

An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.

DC

DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.

Gravity

Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.

Programmable gain amplifier

A built-in amplifier whose gain can be changed in software to make small input signals easier to measure. This matters because choosing the right gain can improve detail for small sensors, but too much gain can make the input range too small.

UART

UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.

voltage reference

A voltage reference is a stable, accurate voltage that a converter uses as its comparison point: an ADC measures its inputs relative to it, while a DAC scales its output to it. A more stable reference gives more consistent results, which matters most in precision sensing and instrumentation.
