What can it do?
Main purpose is to turn things ON or OFF. But it can do lot more than that, swifitch is equiped with header to connect another 4 digital devices and 1 analog. These could be sensors etc.
If you need, by sacrificing one of the data pins, you can get 5V for your 5V sensors.
⛔ Be aware that swifitch's pins are not 5V tolerant and cannot accept 5V on any of the pins provided, and it will damage the ESP.
There are also two jumpers. One is for enabling deep sleep and the other is to put ESP into flash mode when you use conventional USB2UART programmer. We have reused one NodeMCU to make a lot more convenient programmer out of it, because it handles resets and flash mode boot automatically. Details will follow.
What is expected cost?
We have designed swifitch to be both cheap and safe. So it is not ultra cheap but not expensive too. Our cost calculations has stoped at $8! Not bad, what you think?
I would suggest if you wish to build swifitch to check out GitHub with all information what you need for your build. Parts list, tips and tricks etc.
