NRF24L01 RF transceiver
This is a very low-cost NRF24L01 RF transceiver module. This module uses the 2.4GHz nRF24L01 + transceiver, the latest manufactured by Nordic Semiconductor. This integrated operates in the 2.4GHz band and has many interesting new features, such as additional buffers and auto-retransmission.
This nrf24l01 rf transceiver module includes a 100mW amplifier and a low noise amplifier, allowing you to achieve 1000 meters range in the open air.
It can be used in a project without the need for any RF design, simply connect to the SPI interface via an 8-pin connector.
ATTENTION: The module is powered by 3V. But its communication pins tolerate logic of 5V, like that of Arduino.
