Re: Blue Pill for use in commercial product?

I have many blue pills from different vendors. They are cheap and quality is low (some need re-soldering). I don't think it is a good idea to use them in a commercial product.

Re: Seeed Arch Max

I own this board. The led is connected to PB_3 which is also call on mbed: LED1 or D13 (without P).
On my mac, copy the binary in MBED directory does not work. To upload bin file, I need to use openocd.
