Lichee Pi 4 RISC-V SBC


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:


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.
 
For who is too lazy to open links:
The Lichee Pi 4A is powered by the TH1520 processor, a low-power, well-performing RISC-V processor.

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