I've started doing some hardware hacking as part of my new job, I'm amazed at what is available these days. This NodeMCU costs about $5, has built in WiFi, is programmable through the Arduino IDE and can be powered by a small solar panel. I'm blown away.

@gemlog Wow, we're going to have entire computers the size of an SDCard soon

@mhall119 If you don't need a display, that pretty much *is* an entire computer. couldn't you ssh in on the usb connector? Am I wrong maybe?

@gemlog You can probably use screen to connect via serial console on USB (I do that with my NodeMCU), but it doesn't look to have on-board WiFi or Ethernet capability

@mhall119 Let's ask @uaa what he's doing with it -- he's who I learned about it from.

@gemlog @mhall119 well, I don't know why I called to this thread but exactly I have Lichee Pi nano. This board (LPi nano) does not have any network connection but LCD/audio capability.
I think this board is for old ARM (not Cortex but ARM9 core) fans. Here is the processor F1C100s datasheet, please read this and check whether this SoC fits your project. linux-sunxi.org/images/b/ba/F1

@uaa @mhall119 @gemlog
It is because you introduced us to this board and we wondered what your project would be.

@gemlog @gemlog @mhall119 my project... Simply I want to play wih old ARM9 CPU core, not modern Cortex. Now I am trying to port KOZOS, a tiny embedded OS for education. (web page is written in Japanese) kozos.jp/
