Input voltage: 2V - 3.6V
Interface: SPI
Cheap and powerful wireless transceiver. Transmitting using 2.4GHz ISM band with adjustable data rate of 250kbps, 1Mbps and 2Mbps. Transmission range easily exceeds 20m without line of sight. Although powerful, current consumption is low with less than 14mA usage at peak. Internal transmitting redundancies ensure data transferred are not corrupted which simplifies the program of the microcontroller. Startup time is short. Once receive power, the transceiver is ready and transmitting within a second. Signal pins are 5V tolerant therefore requires no logic level converter.
*Power the transceiver with 5V can cause damage.
