RF Setup for NTM88

[chinnanc]

Hi,

Can we use same RF Receiver and LF Transmitter for both NTM88 and NCF29A?

[chinnanc]

My main controller board needs to communicate with both the NTM88 and NCF29A modules, which operate at identical RF and LF frequencies. Is it feasible to use a single RF receiver and a single LF transmitter on the main board to interface with both devices?

Hello chinnanc

Based on the diagram you shared with me, it seems feasible to use a single RF receiver and a single LF transmitter on the main board to communicate with both NTM88 and NCF29A modules, as long as both operate on the same RF and LF frequencies.

1.- Ensure the design has adequate isolation to prevent interference between modules.

2.- If modules respond simultaneously, consider implementing an access control protocol.

I hope this information has helped you, please let me know if you need help with anything else.

Have a great day and best of luck.

Hello chinnanc

Good day!

Yes, In the features section of NTM88 you can find the following:

-  Internal 315/434 MHz RF transmitter

-  Internal 125 kHz LF receiver

We only have application notes of NTM88 working as LF receiver on our official website.

I am afraid NCF29AG-H is only able to receive data via LT and not via RF TX.

I hope this information has helped you, please let me know if you need help with anything else.

Have a great day and best of luck.
