2.6 RF exposure considerations

This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled

environment, for a minimum separation of 5mm between antenna and body. The host product

manufacturer will provide the above information to end users in their end-product manuals.

2.7 Antennas

PCB antenna; 1.6dBi; 2.401-2.480GHz

2.8 Label and compliance information

The end product must carry a physical label, following KDB784748D01 and KDB 784748 stating

“Contains Transmitter Module FCC ID: YZHMDLNRF24L0101”.

2.9 Information on test modes and additional testing requirements

To test the module as a standalone unmodulated constant carrier, refer to Appendix C in

“nRF24L01+ Product Specification.pdf” which is supplied along with this document

As noted in Appendix C, the nRF24L01+ IC requires communication via the SPI lines on the IC.

These are routed to the module connection pins.

The pin definitions are as follows:
