Questions and Answers: 1  MOST (75%) of the lymph goes to the axillary lymph nodes, via the pectoral lymph nodes. (It is extremely important to consider the axillary nodes when performing a breast exam on a patient.) 2  Most of the rest goes to the parasternal lymph nodes. 3  A small amount of lymph goes to the opposite breast.
RF Module. An RF (radio frequency) module is a piece of hardware that receives information from an outside source and sends that information to an RFID Mobile device. Two common types of RF modules used by RFID Mobile are an actual RF module and a barcode scanner.
RF modules are widely used in electronic design owing to the difficulty of designing radio circuitry. Good electronic radio design is notoriously complex because of the sensitivity of radio circuits and the accuracy of components and layouts required to achieve operation on a specific frequency.n RF transmitter module is a small PCB sub-assembly capable of transmitting a radio wave and modulating that wave to carry data. Transmitter modules are usually implemented alongside a micro controller which will provide data to the module which can be transmitted.
