Modify KaKu to WKaKu Power Socket - stodev-com-br/Tasmota GitHub Wiki


I have several of these lying around and they can be used very well with sonoff functionality. As the sonoff PCA is a bit too large I decided to design my own PCA using kicad.


I decided to select the HiLink 5V power supply as it was also favourable on other sites. The relay now has the same connections as the one used in sonoff.


= HiLink 5V power supply HLK-PM01 (aliexpress)
= 5V to 3V3 step down (aliexpress)
= 5V relay OJE-SH-105DM (ebay)
= ESP12-F (aliexpress)
= Capacitors and led from kaku PCA
= 2 x 1k and 1 x 10k Resistors
The image on the right shows how I mounted the ESP12-F vertically. Notice the 10k resistor from GPIO15 to the board.
The firmware used is sonoff without modification!
