borg home-automation

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.

userinter V1.0

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.

light

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.

light 2 V1.0

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.

light 2 V2.1

The differences to V1.0 are:

• Replaced the screw terminals by a 5 pin connector.
• Added a 2 pin connector for output voltage.
This make it possible to have a different voltage on the 3 drivers and outputs than the battery voltage used to supply the logic.
• A jumper to connect Vbatt and Vout.
• A pullup for the reset line.
• Replaced the output connectors with 2.54mm versions.
• Moved analog, I/O and ISP connectors to the upper border so installed LED driver boards will not cover them.
