HiLetgo 4pcs NRF24L01+ Wireless Transceiver Module 2.4G Wireless Transceiver Module NRF24L01 work is a world-wide in the 2.4-2.5GHz ISM band monolithic transceiver chip , a wireless transceiver comprising: a frequency generator mode controller Enhanced SchockBurstTM amplifier transistor amplifier output power modulator demodulator channel selection and protocol settings can be set very low current consumption through the SPI interface , the transmit power when working in the transmit mode when less current consumption is 9.0mA 6dBm accepted mode for the next power-down mode and standby mode 12.3mA current consumption patterns. Ball Open ISM band , the maximum transmit power 0dBm , license-free use . Six channels support data reception 1. Low operating voltage : 1.9 ~ 3.6V low voltage operation 2. High rate : 2Mbps, because the air transmission time is very short, greatly reducing the wireless transmission of collisions ( 1Mbps or 2Mbps software setting air transmission rate ) 3. Multi-frequency: 125 frequency points , multi-point communications and frequency hopping to meet communication needs 4. Ultra-small Size: Built- 2.4GHz antenna , compact , 15x29mm ( including antenna ) 5. Low power consumption : When working in answer mode of communication , air transport and fast start-up time , which greatly reduces the current consumption. Package Includes: 4 * NRF24L01+ Wireless Transceiver Module

Low operating voltage : 1.9 ~ 3.6V low voltage operation. Multi-frequency: 125 frequency points. HiLetgo 4pcs NRF24L01+ Wireless Transceiver Module.
