We are happy to introduce our RS485 MCU Module, a basis of our RS485 system. It is a small board, compatible with Arduino and ready for RS485 wired communication. It was created as a result of our experience with DIY home automation systems, therefore it benefits from lots of our observations and is designed to be convenient to use and install. The most important feature is although its versality - we designed it with having an idea in mind to make it compatible with various shields and wired extensions, which are meant to extend its functionality. A compatible 2 channel AC shield is already finished, but we plan to prepare many other shields such as dimmers, DIN mountable relays, heating modules, sensor extenions and others.
Every shield that will ever appear will be listed here.
Firmware is still under developement, but it is pretty usable right now. For code and instructions look here:
A: Using MySensors RS485 Gateway is an option right now. However we are almost done with our project of single board RS485 Ethernet Gateway. It will be published on openhardware.io soon. Please be patient.
A: Complete instruction will appear soon.
A: Firmware Over The Wire, it is a method of uploading code through RS485 bus, without any need of removing modules from the wall. It is still an experimental feature and sometimes does not work well, but the MCU module is ready for it anyway.
A: Manufacturer provides complete SMD and THT assembly. No need of looking at soldering iron after purchase.
A: Because of small quantities being produced. Growing interest will hopefully let the manufacturer lower the price.
