hi guys.
i wanted to build a rc car and i wanted to know: can i use the nrf24 with the antenna on my controller with the nrf24+ on my car? will i lose range? i was wondering about this because only the controller sends the RF, and the car only receives the signal so since the controller range is large the car wouldn't need to have a large range to receive the signal.
will this work?
thanks!
I think that should work fine. I have had a pair of the low power nRF24s (with PCB antenna) working at 110m range outdoors with clear line of sight. With the high power module the range should be considerably longer.
AFAIK most of the off-the-shelf 2.4GHz RC controllers use those nRF24 modules or their Cypress equivalent. (The Nordic and Cypress modules don't work with each other).
cool, thx for the reply!
i'll try this out then. since the antennaless version is more cheap, i'll save a few bucks buying one of each instead of 2 with the antenna, and i'll be able to have a car without the antenna hanging out.
I suggest you buy at least 3 so if you have doubts about one of them working you can try another.
Get at least one of the examples in my tutorial working before you try anything else.

There are high power versions of the NRF24L01 modules that have an onboard antenna.
Like SMD 2.4G NRF24L01 1100 meter long-distance NRF24L01+PA+LNA SMD wireless modules 1100meters €2.61
or 2.4G SMD NRF24L01 1100 meter long-distance NRF24L01+PA+LNA SMD wireless modules 1100meters €1.50

Interesting. Have you any experience of them?

No, I did not perform real tests with them, I just tried the first variant and it worked.
I like the small normal modules
SMD NRF24L01 Wireless Module SI24R1 Mini module wireless data transmission module €0.77
I connect them with
10Sets Male & Female Cable Connector XH 1.25 JST 8 Pin Single Head Plug With 10cm Electronic Wire Connectors €1.44
I don't own the second variant yet, they are still on their journey.
