BL-M8812EU2 Wi-Fi Module (RTL8812EU)
BL-M8812EU2 is a high-performance single-band Wi-Fi module based on the Realtek RTL8812EU-CG chip, designed to operate in the 5 GHz band. It supports the IEEE 802.11a/n/ac standards and provides data rates up to 867 Mbit/s. The module supports several channel-width modes: 5 MHz, 10 MHz, 20 MHz and 40 MHz (reception). Thanks to its integrated power amplifier and narrowband modes, it is ideal for long-range wireless video transmission — in particular for FPV drones and IP-camera systems.
