This section provides information to help carry out a successful schematic and PCB design.
Do not load Pin 4 (ANT_DETECT) with a capacitance more than 1 nF.
4.1 Pin assignment
The pin assignment of the ZED-F9T module is shown in Figure 28. The defined configuration of the
PIOs is listed in Table 22.
The ZED-F9T is an LGA package with the I/O on the outside edge and central ground pads.
