Summary of P2 – WIFI Web Power Switch for MAINS – MPSM v.2 DevBoard – ESP8266
The MPSMv2 is a compact ESP8266 development board featuring an integrated mains power switch and direct web interface access. Measuring approximately 25x50mm, it offers full pinout accessibility via two breadboard-friendly expansion slots for future projects. The board undergoes a mandatory 24-hour test before shipping to ensure reliability.
Parts used in the MPSMv2 DevBoard:
- ESP8266 microcontroller
- Mains Power Switch
- Breadboard friendly expansion slots
- PCB (Printed Circuit Board)
Because of the high interest in the subject, a new dedicated Dev Board has been born: MPSMv2, a small ESP8266 DevBoard with integrated MAINS Power Switch!
Yes, it’s finally here, arrived safely from the PCB factory and you can see it below. I know a lot of you are waiting it already, but please be patient few more days. None of the already requested ones will leave the premises without a proper 24 hour test.
For any new requests please feel free to use as usual: tech at esp8266-projects.com.
If you want for your own experiments to order CBD v2 EVO bare PCBs only, you can also do it directly at Dirty PCBs, our preferred PCB House:
I don’t know if this it’s the smallest MAINS Power Switch with integrated WIFI and direct Web interface access but if is not, it’s definitely closer to be at only around 25x50mm 🙂
As you can see from the PCB picture above you have even a full ESP8266 pinout access thru 2 breadboard friendly expansion slots for future projects development.
Finally, the received result from the PCB Factory, a long awaited moment:
