I have an idea is that if implemented could mean that Itead would get a broader market to sell more hardware to.
The idea is that Itead should consider making the Sonoff series more hacker-friendly by added a micro-USB port (with USB to serial build-in) on them all in order to make flashing the firmware much easier without soldering.
If all Sonoff devices had an micro-USB port so that just about anyone could flash any Sonoff devices with third-party firmware without soldering then I believe that the worldwide hacker-community could make your Sonoff devices famous and more popular than any other smart home / home automation devices.
I believe this because people love the functionality of ESP8266 devices with third-party firmware but most people are not comfortable to solder on their own.
In conclusion; if you built-in USB to serial to make flashing firmware easy for anyone then the worldwide hacker-community would make the tools needed to make it is even more easy and you could sell much more hardware.
We will consider it.
