Firefly-RK3399 was the very first Rockchip RK3399 development board when it launched in late 2016, and it mostly stayed that way until others joined in late 2017, early 2018 with products like Orange Pi RK3399, ODROID-N1, Rock960, or Pine64 RockPro64 among others.
Firefly team has now unveiled another higher end “all-in-board industrial board” with their Firefly AIO-3399J board featuring their RK3399 CoreBoard module, and a baseboard exposing plenty of I/O and connector, including support for M.2 drives, and 4G LTE mini PCIe cards.
