After more than 6 month of using MDMSNode "Lighting" I decided make some improvements for this device. And now I want to present the new revision (Rev 1.1).
So, what have been changed?
TRIAC managing. For limiting the rate of change in voltage or current (di/dt or dv/dt) and over voltage during turn-on and turn-off I decided add snubber circuit - 39 Ohm + 0.01uF parallel the TRIAC.
SMD version NRF24L01. After last my order on Aliexpress I had so many problems with DIP NRF24L01 and decided use SMD version.
Cutout for NRFL01 antenna.
