Lichee Pi 4 RISC-V SBC

i thought there was a thread on RISC-V but could not find it .

I like the idea of Risk-V. Although I didn't develop for it myself, I like to get familiar with the platform as it feels promising.

some Risk-V things I posted about:

The Communication Cube

I already live a life in service to others, but I’m not allowed to come into contact with any of the people I serve Now we know where you work. https://yewtu.be/watch?v=8XF57Ds5jxI https://yewtu.be/watch?v=EdT_KVqewNQ

Precursor

Mobile, Open Hardware, RISC-V System-on-Chip (SoC) Development Kit

I must have been more, but I can't find those. I must have a bunch of cheap aliexpress risk-v development board links somewhere.

Thing costs 140 on amazon.
Really like the modular design. Wonder whats its power usage is.
Since the chip is blank without heatsink it should be extremely low.

He did a review on this 7 months ago. its not as powerful as the new board.
