Shenzhen Xunlong has launched several cellular IoT boards over the last few years with Orange Pi 2G-IoT, Orange Pi 3G-IoT and Orange Pi 4G-IoT, but each time, they are launched with Android support only. Linux support on the 2G board has never been great, while the Android 8.1 SDK for Orange Pi 4G-IoT was released earlier this year, but no Linux image are available.
This leaves us with Orange Pi 3G-IoT board that just got its first Linux based firmware images released today on both Baidu and Google Drive cloud storage storage services.
Four images are available for Orange Pi 3G-IoT-A (256MB DDR2) and Orange Pi 3G-IoT-B (512MB DDR2) boards with images booting from eMMC flash or micro SD card. A shell script (tar_image.sh) is provided to flash the image to the micro SD card since the latter for follow a specific partition layout.
