COMPONENT LOCATOR GUIDES

RF BOARD COMPONENT LOCATOR GUIDE (UHF)

The following guide can be used to locate components on the 430-470 and 470-512 MHz RF board layouts on pages 6-8 and 6-11. Refer to the grid around the board to determine the approximate location of a component.

NOTE: When the location of a component is different on the board unrevised 430-470 MHz board, the location on the unrevised board is listed first and the location on the revised 430-512 MHz board is listed second.
