Jargon buster
Plain-language definitions for the technical terms used above.
- EEPROM
- A type of non-volatile memory that keeps stored data even when power is turned off. In a sensor module, it can be used to store settings or calibration data so they do not need to be re-entered every time.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
- USB 2.0
- USB 2.0 is a wired connection standard used for data and power between a device and a computer or compatible host. For this camera, it tells you what kind of port it plugs into and helps indicate whether older or newer computers are likely to work with it.
