MangoPi R4

Are there any news about MangoPi R4?
Can we get more details about planned features?

R4 (unreleased, add WiFi on the basis of R3, add 16 extra IO,
                add AXP power management,
                add lithium battery charge and discharge and boost, RTC)

quite interesting :+1:



Due to the crazy price increase of f1c chips, the production plan of R4 will be until late December.
We made the R4 version to make the final version of F1c200s.
