nrf24l01 module location on pcb.

[Fabio Fernandes]

I am using NRF24L01 modules sold on ebay. I have 3 boards where these modules are soldiers and notice a big difference in range. More distant of other components, better range. What is the safe distance to other components of the pcb? Thanks

In the #1 board the range is ~20m

In the #2 board the range is ~10m

In the #3 board the range is ~5m

The experiments were always performed at the same location with the same power supply. I changed the radios to eliminate the possibility that the radios had difference.

Thanks.
