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.
Hydrogen bonding is important in many chemical processes. Hydrogen bonding is responsible for water's unique solvent capabilities. Hydrogen bonds hold complementary strands of DNA together, and they are responsible for determining the three-dimensional structure of folded proteins including enzymes and antibodies. simple way to explain hydrogen bonds is with water. The water molecule consists of two hydrogens covalently bound to an oxygen. Since oxygen is more electronegative than hydrogen, oxygen pulls the shared electrons more closely to itself.
