Controller Overview
This section provides a detailed circuit description of the APX 3000 controller design. The controller
design consists of the following board and flexes:
Printed Circuit Boards
• Main Board
Flexes
• Main Flex
• Side Controls
• Top Control
• NFC with LED
The controller interconnection diagram (Figure 3-12) shows the various physical components of the
design, along with how they are all connected. It also shows the key distinguishes between a flex
connection and a board-to-board connection. A brief description of each of the components is
provided below.
