Features:<br> RF1101SE micro power wireless data transmission module, using high-performance CC1101 wireless communication chip (an improved version of CC1100 chip, superior to CC1100, and seamlessly replaced, with identical program)<br> The high transmission rate can reach 500Kbps, and the rate can be modified by software. The transmission distance in open areas can reach 200-300 meters, and it has functions such as wireless wakeup. Sensitivity reaches -110dBm, with high reliability<br> Software can modify rate parameters to better meet the usage requirements of customers under different conditions. High rate: faster data transmission rate.<br> Low rate: strong anti-interference and penetration ability, longer transmission distance<br> Can be widely used in various short distance wireless communication fields, such as wireless meter reading, industrial remote control, low-power handheld devices, etc<br> Wireless wakeup function, supporting low-power electromagnetic wave activation function, wireless wakeup of low-power sleeping devices<br> <br> Specifications:<br> Working voltage: 1.8V~3.6V, recommended for 3.3V operation<br> Operating in the 433MHz frequency without license<br> High working rate of 500kbps, supporting 2FSK, GFSK, and MSK modulation methods<br> High sensitivity 1.2Kbps -110dBm<br> Built-in hardware error detection and address control<br> Lower current consumption (in RX, 15.6mA, 2.4Kbps, 433MHz)<br> Programmable output power, up to +10dBm for all supported frequencies<br> Support automatic channel access cleaning before transmission<br> The module can be software addressed<br> <br> Note:<br> Due to lighting effects and shooting angles, there may be slight variations in product appearance. Please allow 0-1cm error due to manual measurement.<br> <br> Package includes:<br> 1 Set Wireless Data Transmission Module
