Features

• 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 :)
