Pad description
When used on a motherboard the boundary pads on the SPMB250-A1 can be used to get
the connections with the remaining part of the circuit present on the motherboard itself.
The meaning of the pads is listed in the following table:
Table 4.
LED indicators
Two LED L2 (Led2) and L3 (Led3) are connected to the GPIO of SPZB250 module to be
used to monitor the module activity. Driving pin of L3 is also available as pad out (P10).
