  • XPICO Wi-Fi Bottom PCB pads

    Hello,
    I'm trying to prototype an application with interchangeability between the XPICO Wi-Fi and the XPICO 110 (Ethernet SMT) modules. They do have the same package and pins do change minimally, but in the application with only power, UART and some CP lines is not a problem. I don't have a problem with the majority of the pads (the castellated ones). My issue is with the line of pads under the device which have only ground and reserved (JTAG) signals. Are these ground pads required for proper operation or they can be left unconnected? The 6 thermal gnd pads are ok.

    Thanks

    The GND pins need to be connected to signal ground. The RSVD pins must be left floating, and RF1_CTL may be left floating.
