Ideal for remote sensors, robotics, home automation, telemetry, and general prototyping, the HC-12 creates transparent point-to-point or controller-to-device links for commands, status updates, and data logging. Use it to replace short wired serial connections with a compact \u003cstrong\u003e433MHz transceiver\u003c\/strong\u003e that integrates easily with projects using standard TX\/RX serial interfaces.\u003c\/p\u003e","brand":"ShillehTek","offers":[{"title":"Default Title","offer_id":52709889147167,"sku":"AA485","price":12.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4340\/8415\/files\/hc12-433mhz-wireless-transceiver-module-01.jpg?v=1786597203","url":"https:\/\/shillehtek.com\/products\/hc-12-433mhz-serial-transceiver-si4438-arduino-esp32","provider":"ShillehTek","version":"1.0","type":"link"}
