We worked recently with our friends at T4 Sustainability to produce some Raspberry Pi breakout boards for their Open Source Building Energy Management System (oBeMS) project.
oBeMS is a project to produce an integrated building management system which comprises of sensors, actuators, control and monitoring systems.
More information and an overview of the project is available here:
The RPi is loaded with the oBeMS software. This is available via T4 Sustainability.
The populated PCB with a RPi 2+.
Showing all the components. The large black unit is the 240V to 5VDC regulated power supply. This is medical grade output.
All connectors are plug-in screw terminals. The AC supply can be seen to the right. This unit is designed to be fully enclosed in an enclosure to ensure AC safety.
The PCB design is here as a .pdf:
The PCB design has been produced with KiCAD.
