So yesterday, i finally i got this, but had no idea how to i get it to work.
I connected it correctly to 3v tx rx ground. But it does not boot up.
USB to TTL with correct pins.
At the back is a mini usb. Connected to it, and also doesn't have any response.
The schematics someone uploaded. Did it according to this guide.
According to various videos and guides, it seems i need to "short" ground to ground or something. On other non assembled models, there is indication of BOOT, but this assembled one doesn't show.
Great. Just found out using translate. So that means i need to find a way to connect it to boot, but i don't have enough f to f jumper wires !
I have properly shorted the ground to boot, but no response. I'm starting to think this is faulty.
Explanation why this proj can be a total failure. Firstly, i opted for the pre-assmbled model. But this model doesn't have anyone on the interweb with guides. Secondly, i've never done soldering and probably never will. It will take up 90% of my time as i'm not a pro in this field.
So that's the end of it. On hold till i have lots of spare time.
