DLP-RFID2D USB Dongle. 1.0 INTRODUCTION. The DLP-RFID2 is a low-cost, compact module for reading from and writing to HF RFID transponder. tags via an internal or external antenna. It has the ability to both read and write data in addition to. reading the unique identifier (UID). All of the DLP-RFID2âs electronics reside on a single, compact. PCB, and all operational power is taken from one 3.0- to 5.0-volt supply. An external antenna can be. connected via a standard u.fl connector or IO pin/pads.
Quick Answer. Water molecules have covalent bonds. Each molecule consists of two hydrogen and oxygen covalent bonds. However, when water molecules are placed together, as they are normally, the hydrogen atoms in each molecule can form hydrogen bonds with the oxygen atom of other molecules. Continue Reading.
The H 2 molecule is a good example of the first type of covalent bond, the nonpolar bond. Because both atoms in the H 2 molecule have an equal attraction (or affinity) for electrons, the bonding electrons are equally shared by the two atoms, and a nonpolar covalent bond is formed. good example of a polar covalent bond is the hydrogen-oxygen bond in the water molecule. Water molecules contain two hydrogen atoms (pictured in red) bonded to one oxygen atom (blue). Oxygen, with six valence electrons, needs two additional electrons to complete its valence shell. Each hydrogen contains one electron.
