The borg home automation project is a collection of PCBs including software for controlling everything in a house. This includes lights, fans, power sockets, water pumps, etc.
Every board contains an AVR microcontroller, an ISP connector, RS485 interface and a 24V/5V DC/DC converter.
The user interface PCB. Next to the standard wires there is only a connector for buttons and LEDs and a connector for a 24V/5V DC/DC converter module.
The light PCB. Contains a 24V/5V DC/DC converter and 3 LED current sources. This PCB has been canceled. Maybe it will be resurrected with only one LED driver and smaller PCB size.
LED driver PCB with PT4115. Panelized PCB containing 5 complete circuits.
Second variant of the light PCB. Next to the usual parts it contains 3 conectors for LED drivers or compatible boards, an I/O connector for 230VAC dimmers or fan control, and an analog connector for measuring analog signals.
The differences to V1.0 are:
USB Power is a PCB providing 5V and up to 680mA to two USB sockets.
