BL-M8812EU2 Wi-Fi Module (RTL8812EU)
RTL8812AU
RTL8812AU is a time-proven, if somewhat dated, Wi-Fi chipset with solid performance. Despite its relatively high cost, it enjoys wide community support, especially among FPV enthusiasts. Thanks to high-quality drivers, the RTL8812AU supports 5 MHz, 10 MHz, 20 MHz and 40 MHz modes — both for reception and transmission. This allows high bitrates to be achieved even over long distances.
📊 For example, on 21.04.2025 a total bitrate of 52 Mbit/s was recorded, of which 36 Mbit/s was video.
