RockPro64 was the most aggressively priced of the lot as it was expected to launch for about $60. The good news is that Pine 64 is now selling the first production batch for $59.99 (2GB RAM) or $79.99 (4GB RAM). The less good news is that software is still being worked on so the company only recommends it for early adapters and developers.

I could not find documentation nor firmware images yet, but I’ve been told that Rock64 images (Debian, Ubuntu, Android, etc..) work with some tweaks such as updated Device Tree (.dts) file. The boards are expected to ship in the first week of May, so we should have more clarity about available firmware images at that time.
The boards do not ship with all accessories by default so you may want to add the heatsink ($2.99) a power supply ($8.99 to $11.99), and optionally the wireless module ($14.99), as well as PCIe card to connect two SATA drives ($9.99), or an M.2 NVMe SSD ($5.99).
