Not worth your time or money
Color: 2.8 Inch ST7789 TN Touch
Not at all as it was portrayed. The “detailed” instructions aren’t helpful at all. There is no case with it, just a board. Apparently we are expected to seek out and download extra firmware which we only found out by reading comments from other frustrated customers. Very disappointed as we thought this would be a fun gift… so we bought three of them. Didn’t think anything of it until Xmas when the gifts are opened, projects started and realizations set in. Don’t waste your money or time. ... show more

title is misleading, this is just the dev board no miner installed
Color: 2.8 Inch ST7789 TN Touch
it works, you need to flash it yourself. If you only read the title you will be mislead, this is just the board the miner is not installed.

Have to install software and maybe sign up for service l. Not sure
Color: 2.8 Inch ST7789 TN Touch
Have to install software, they sign up for a service of some sort, instructions not easy to follow but I haven’t had enough time to try and get it all done. So far it’s a bit of work to get it to work…
