Hub
About the Hub PCB
Hub is an open source PCB design by NerdyProjects, published on GitHub. It is a 2-layer board measuring 24.5 × 59 mm, with 15 components from 8 distinct parts.
Other key parts include the MP2315-Mini-Module. By type, the board carries 10 connectors, 3 diodes, 1 IC and 1 capacitor.
From the project
(Yet another) house bus hardware based on STM32F072 and the CAN bus
This repository holds hardware and software design for a work in progress house bus system. It operates using a 4-wire bus using the CAN bus as well as supply of ~10 - 20 V. It should provide a base for very simple nodes (e.g. sensors, digital actors) as well as more complex nodes (e.g. a heating system controller).
The system design started in November 2017 when the need of a better heating system controller arose in a housing project in Wurzen, Germany. The gas heating system, a well overpowered Viessmann Atola controlled by a Viessmann Trimatik MC should be better controlled in light load…
