nRF24L01 Product Specification
PCB layout examples
Figure 31. on page
70,
Figure 32. on page 71
and
Figure 33. on page 71
show a PCB layout example for
the application schematic in
Figure 30. on page
69.
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.
