Designed for HD VTX, it removes the OSD chip AT7456E and also added support for external GPS through Betaflight 4.4.0.\u003c\/div\u003e\n\u003cdiv style=\"text-align: left;\" data-mce-style=\"text-align: left;\"\u003e\u003cimg src=\"https:\/\/cdn.shopifycdn.net\/s\/files\/1\/1778\/6615\/files\/2fcff80837b53a294056d927199f8372_2ee17f2b-f7b3-49b9-8b8b-eed797ebd3e8.jpg?v=1684721998\" alt=\"FC 1S 12A AIO FC V3\"\u003e\u003c\/div\u003e\n\u003ch2\u003eBullet Point\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan data-mce-fragment=\"1\"\u003eF4 1S 12A AIO Brushless FC V3\u003c\/span\u003e is specially designed for HD VTX, the MCU with stronger performance and computing power, and the new BEC solution with 5V 3A output supports HD VTX power supply.\u003c\/li\u003e\n\u003cli\u003eIntegrate Serial ELRS 2.4G receiver, 16M black box, barometer, current meter, reserve 2 complete serial ports, and 1 standard SBUS. It is compatible with various devices such as GPS, HD VTX, and external receivers, which reduces the overall weight and complexity of the build.\u003c\/li\u003e\n\u003cli\u003eWith a \u003cspan data-mce-fragment=\"1\"\u003elighter weight of \u003c\/span\u003e4.2g, it improves flight performance and agility.\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eThere are 2 main control MCUs available: the STM32F405 and the AT32F435.
