Unlike the Sonoff Micro, The Sinilink actually feeds the data pins through.
Also, It's an ESP8285, so it can be flashed with Tasmota!!!
NOTE: The housing on the female USB connector is NOT grounded. This is important if you decide to attach a wire to GPIO-0 on the little contacts & ground it for booting to flash-mode. (No need to ask how I learned this...)
Adventures in careful work
I bought 2 of these a while back & took a long time to work up the nerve to flash them.
Rather than go hunting for 1.27mm pitch pin headers or tiny little pogos, I soldered 30AWG wire-wrap pigtails in the holes. Then I used my prototype ESP-Everything! programmer on them.
In the process, I discovered that the button doesn't seem to be on GPIO-0... So I went back & added wires to GPIO-0 & RST. (Then found out about the non-grounded connector)
Eventually tho... Got it working.
W00t!
Some thoughts
There has been discussion about whether this sort of device is actually useful.
I've found a good reason to have at least one.
I've plugged my programmer through one into my dev machine. I can now disconnect the programmer without physically unplugging it.
