DD-100

Product Details

The term DD-100 is commonly used for various small electronic modules or components, often referring to a compact digital display module, DC-to-DC converter, or DIY electronics part depending on the manufacturer. In many hobby and electronics markets, a DD-100 is typically known as a digital voltmeter/ammeter module, designed to measure DC voltage and current with good accuracy. These modules often feature a bright LED display, simple two-wire or three-wire connections, and can run directly from a DC power source. A DD-100 module is valued for its compact size, making it easy to integrate into power supplies, battery chargers, DIY amplifier boards, inverter panels, and testing equipment. The clear numerical display helps users monitor voltage levels, load conditions, and system performance in real time. Some variants also include features such as auto-calibration, reverse-polarity protection, and multi-color LED digits. Because of its practicality, the DD-100 is widely used by hobbyists, technicians, and DIY builders who need a reliable and easy-to-install measuring display for their projects.
