My new development: two-channel touch mini switch with glass panel on batteries. Now the development is at the stage of software testing. This version of the device was made to control the roller blinds, but can be used anywhere and in any way. The prototype is ready, power consumption tests have been successfully passed. The height of the gadget is 11 mm, the Board dimensions 42mm x 42mm. This touchpad can work in master slave mode with my other devices.

On Board the device are: Glass panel 47mm X 47mm nRF52832 tp223 three-color led buzzer TPS610981 cr2477 SWD (micro) Serial (micro)

...I hope this development will deserve your like
