Yo! This project is still a Work In Progress. Instructions, board layouts and BOM might change!
Mini Dimmer Box
Donate to support Open Hardware
Stand alone atmega8a controller to reliable dimming. It is connected with main controller via i2c
Board is relatively "green". Zero crossing detection circuit can be disconnected when dimmable device is switched off. So consumption is minimized.
Very small board (37x39mm). Fits very nice plastic box.
Well tested embedded power supply with a lot of protections (used in mini relay box and wall socket insertable node)
JST for external button.
Atsha 204, spi flash, acs712, rgb led...
I am testing the prototype now :)
