Electrical aspects common for both solutions
4.1
Location of pins
The following figure shows the position of contacts 1, 9, 28 and 36. Pin
numbering has been done counter-clockwise.

This figure applies for both NRP H90-RE and NRP H90-RE\F8D8.

General signals
4.2.1
Supply voltage
The NRP H90-RE requires 3.3 V DC power supply to operate. This is
provided via pins 10 and 37 for the +3.3 V power supply (s3V3_01
and +3V3_02) and pins 9 and 36 for ground (signals GND_01 and
GND_02). The SYS-LED indicates the current system status of the module.
Note:
Power supply and ground should be connected at the shortest
distance to the power and ground plane of the host system. Use a
ceramic capacitor with 10 µF between the pins for decoupling the
power supply.
Only a single 3.3 V operation voltage is needed to operate the netRAPID.
The voltage must be regulated and can have a tolerance of ±5% (3.15 ‑
3.45 V) and must be connected twice to the netRAPID chip carrier. The
power has to be supplied between pins +3V3 and GND.
