PCB Layout Example, Single Ended Connection to 50
W
Antenna
Figure 38 shows a PCB layout example for the application schematic in Figure 37.
A double-sided FR-4 board of 1.6mm thickness is used. This PCB has a ground plane on
the bottom layer. Additionally, there are ground areas on the component side of the
board to ensure sufficient grounding of critical components. A large number of via holes
connect the top layer ground areas to the bottom layer ground plane.
a) Top silk screen
No components in bottom layer
b) Bottom silk screen
c) Top view
d) Bottom view

Configure the Chip as nRF905.
nRF9E5 is easily configurable as nRF905. Upon power up the boot loader is run. If
MISO is set to low value during the first 10ms, the microcontroller configures itself to
nRF905 mode. All pins are then defined as for the nRF905 chip.
