From Apr.15~Apr.18, I kept it run “top” on the board and every 5 minutes my script sent one test.bin file(about 2MB) to board /tmp/ folder through wifi.
Now after 72 hours, its free memory is 6.5MB compared to 9.9MB at startup. Its temperature is about 65C at end(house about 24C) without heat sink. Looks good for me. 🙂
Wow!!! I just found your blog and have read from start to the end. It is very impressive work. It is not only the smallest board but probably the only board that brought out all the GPIO pins.
Thank you for your reply 🙂 I just make it as an artwork but not only a module.
