FriendlyELEC NanoPi NEO3 Plus is a very compact headless SBC featuring a Rockchip RK3528A SoC with 1GB RAM, including main interfaces like a Gigabit Ethernet port, a USB 3.2 port, and a 26-pin GPIO header.
I recall using its predecessor, the NanoPi NEO3, which is based on a Rockchip RK3328, which I reviewed with Armbian in 2020. The updated model shares similarities, with a quad-core Cortex-A53 SoC clocked at 2.0 GHz, and it is offered in a black metal case instead of white plastic. The OS can still be booted from a microSD card, but NanoPi NEO3 Plus includes a socket for an optional eMMC flash module, an RTC battery connector, a speaker connector, and a MASK button for firmware updates.
