A Raspberry Pi Zero is $5, runs ARM, has tonnes of community support, and is available to ship outside of china. If you look at taobao/aliexpress/ebay, there are also hundreds of RPI clones and ARM development boards and even FPGA boards < $10. What makes this interesting?

I’m tempted to buy one just to play around with an unconventional ISA. I don’t think this is meant to be a Pi alternative.

You might want to look at ESP8266 instead.

I'd vote ESP32 in addition to the ESP8266.

I’ve got about a dozen ESP8266 dev boards, but they are not in the same league as this. ESP8266 is just a WiFi-enabled MCU. Getting any kind of video output or even keyboard input from it is a hack, and forget about it running Linux.

I wonder what the power requirements are? If they're substantially less than the Pi Zero, perhaps it has a use case?
