Intelligent relay bypass VS Intelligent DPDT relay bypass question

[dbeasley]

Hello everyone! I intended to purchase 6 of the Intelligent relay bypass boards, but accidentally bought 4 of those, and 2 of the intelligent relay DPDT boards.

My goal was to build a pair of "ABC" Y boxes. That is, there would be a single input that could be routed to 1 of 3 different outputs exclusively. My thought was to use the intelligent relay bypass module in "Channel Switching" mode to that when i stepped on any switch, the signal would route to that specific channel and un-route for where it was previously.

In looking at the Intelligent relay module VS the DPDT module, not a whole lot looks different - I see they both have the same values on the silkscreen, with the I/O pads moved to different spots, as well as the power IN pads. both even have CTRL pads.

My question is, would it be fine to use the DPDT pcbs I have for this, and would "Channel switching" mode be present with the pre-programmed ATTINY MCU for them?

Or if not, could I just buy a pair of MCUs meant for the Intelligent relay module?

Thanks.

They both use the same microcontroller so they behave identically.

You can wire up the DPDT switch to do the same job as the Bypass module (more technically, since you aren't bound to the true-bypass wiring scheme).
