In this mode, the module can also set the 8 serial port baud rates as shown in the\u003cbr\u003e\u003cbr\u003e• HC-12 Power Supply Voltage: 3.2V~5.5V. (If the module is to be in the transmitting state for a long time, it is recommended to connect a 1N4007 diode in series when the power supply voltage exceeds 4.5V to avoid the built-in LDO heating of the module).\u003cbr\u003e• Default Communication Distance(open field test): about 600m (the communication distance can be adjusted up to 1000m, the air baud rate is 5000bps).\u003cbr\u003e• Default Idle Current: 16 mA (module operating current is different in different operating modes).\u003cbr\u003e• Operating Frequency Range(433.4-473.0MHz, up to 100 communication channels), maximum 100mW transmit power (settable).\u003cbr\u003e• Default Factory Setting: working mode FU3, baud rate 9600bps, communication channel CH001 (433.4M).","brand":"Coliao","offers":[{"title":"Default Title","offer_id":52137047032090,"sku":"MCAB0C7M99BQM","price":21.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0965\/6772\/2266\/files\/71uSV15nlDL.jpg?v=1777370937","url":"https:\/\/craftedyogi.com\/products\/2pcs-hc-12-433mhz-si4463si4438-wireless-serial-port-module-1000m-replace-bluetooth-with-antenna","provider":"Craftedyogi","version":"1.0","type":"link"}
