The minew g1-c is a smart home gateway / BLE gateway. A Nordic nRF52832 is available via USB UART (cp210x) to support BLE. The LED ring is a ring of 24x ws2812b connect to a generic GPIO (unsupported). There is a small LED which is only visible when the device is open which will be used as LED until the ws2812b is supported. The board has also a micro sdcard/tfcard slot (untested). The Nordic nRF52832 exposes SWD over a 5pin header (GND, VCC, SWD, SWC, RST). The vendor uses an older OpenWrt version, sysupgrade can be used via serial or ssh. CPU: MT7628AN / 580MHz RAM: DDR2 128 MiB RAM Flash: SPI NOR 16 MiB W25Q128 Ethernet: 1x 100 mbit (Port 0) (PoE in) USB: USB hub, 2x external, 1x internal to USB UART Power: via micro usb or PoE 802.11af UART: 3.3V, 115200 8n1 Signed-off-by: Alexander Couzens <lynxis@fe80.eu>
