Features:RF1101SE micro power wireless data transmission module, using high-performances CC1101 wireless communication chip (an improved version of CC1100 chip, superior to CC1100, and seamlessly replaced, with identical program)The high transmission rate can reach 500Kbps, and the rate can be modifies by software. The transmission distance in open areas can reach 200-300meters, and it has functions such as wireless wakeupSensitivity reaches -110dBm, with high reliabilitySoftware can modify rate parameters to better meet the usage requirements of customers under different conditions. High rate: faster data transmission rate.Low rate: stronge anti-interference and penetration ability, longer transmission distanceCan be widely used in various short distance wireless communication fields, such as wireless meter reading, industrial remote control, low-power handheld devices, etcWireless wakeup function, supporting low-power electromagnetic wavesactivation function, wireless wakeup of low-power sleeping devicesSpecifications:Working voltage: 1.8V~3.6V, recommended for 3.3V operationOperating in the 433MHz frequency without licenseHigh working rate of 500kbps, supporting 2FSK, GFSK, andMSK modulation methodsHigh sensitivity 1.2Kbps -110dBmBuilt in hardware error detection and address controlLower current consumption (inRX, 15.6mA, 2.4Kbps, 433MHz)Programmable output powers, up to+10dBm for all supported frequenciesSupport automatic channel access cleaning before transmissionThe module can be software addressedNote:Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand. Please allow 0-1cm error due to the manual measurment.Package includes:1Set Wireless Data Transmission Module
