• The top side of the Wireless CPU
connected to the application board via a flex cable connector
Note :
The bottom side of the Wireless CPU
®
better Wireless CPU immunity to noise generated on the application board.
For installation of the Integra M2106+ Wireless CPU
• Use the recommended footprint described in Figure 22, if the bottom side of the Wireless CPU
the application and reverse it, if the top side is on the PCB
• Connect the metallic pads around the fixing holes (1, 2, 3 & 4) of the Wireless CPU
board ground
Notes :
• If the connection of the 4 holes is not possible, at least 2 holes on opposite corners (e.g. 1 & 3 or 2 &
4) must be connected to the ground board
• For a better ground connection, it is recommended to use a ground plane on the application board
• If the Integra M2106 Wireless CPU
strongly recommends using fastening systems, which allows enough clearance to connect the
