Rockchip RK3399 - the NanoPi NEO4

I don't have any of these, but the Neo4 is a tiny little board with an RK3399 and 1G of ram.

My main objection to these is the fine pitch (1.27mm) connector for the IO pins.

Tempting for $60, but those IO connectors look challenging.

The connector you need is a Harwin M50-4302045.

Have any comments? Questions? Drop me a line!
