GL.iNet GL-AR750 is a small size, dual-band (AC750) router, based on Qualcomm/Atheros QCA9531 v2 + QCA9887. FCC ID: 2AFIW-AR750. Specification: - 650/597/216 MHz (CPU/DDR/AHB) - 128 MB of RAM (DDR2) - 16 MB of FLASH (SPI NOR) - 3x 10/100 Mbps Ethernet - 2T2R 2.4 GHz (QCA9531) - 1T1R 5 GHz (QCA9887) - 1x USB 2.0 (power controlled by GPIO) - 1x microSD (GL857L) - 3x LED (all driven by GPIO) - 1x button (reset) - 1x 2-pos switch - header for optional PoE module - 1x micro USB for main power input - UART + I2C header on PCB Flash instruction: Vendor firmware is based on OpenWrt/LEDE. GUI or sysupgrade can be used to flash OpenWrt/LEDE firmware. Signed-off-by: Piotr Dymacz <pepe2k@gmail.com>master
