Description Directly build wireless relay, IOT project with this simple receiver and elegant transmitter. On board RF 433/315 mhz Receiver SYN470 On board Decoder, support and match with other encoder chip like PT2262 (fixed code), find the PT2262/2272 kit here.(it is 315mhz) EV1527 (learning code), you can find the nice look and safety receiver here. Wireless switch relay use EV1527 here. and other transmitter encoder ICs like 2260、2262、2240、1527 On board status LED, when signal receive/learning/finish learning, LED will indicate Up to four direct digital signal output, match up four buttons on remote transimitter Necessary pin pre-soldered, extra 4 optional pins can be soldered later (ANT, GND, LED, SW) LED -status LED, SW – learning switch button can lead out, on use built on board Specifications: Sensitivity: -110dBm Power: 3.3V-5.5V Power consumption: 5.0V @ 315MHz, 2.5-2.8mA continuous data transfer rate to 2.4K (Manchester encoding) Good selectivity and spurious radiation suppression, easy to pass CE / Fcc international certification; Good local radiation suppression, can be a number of receiver modules work together (ie, single-fat and more income) and will not interfere with each other, with the use of does not affect the receiving distance. Temperature range: -30-85 ℃, even in harsh ambient temperature can work properly; 28 x 12.5 x 5.00 (mm). Applicaton: Car Remote Door Switch (RKE), Remote control to open the door machine, Wireless security alarm, Remote control curtain machine, Wireless Industrial Controller, Wireless data transmission Documentation please see on this page, working principle see on this page. This board used a custom chinese IC, similar to EV1527, but we are NOT able to provide shematic or IC datasheet info. Package inlcudes board and antenna.
