Hello, This module is finally available to buy assembled. Now our project is complete, you can run the whole RS485 system after some shopping here, on openhardware.io. See details on the project pages. Cheers, feanor-anglin

@kimot in theory you might be right, but in practice... it just works. The propability of collisions is extremely low and this is, as far as I know, the only problem you can worry about. After all, it was not my idea to use MySensors with RS485: https://www.mysensors.org/build/rs485
