[OpenTRV-dev] Custom Arduino shield

[Stuart Poulton]

Hi,

Actually for the cost of producing a shield, you can include the space for the ATMEGA328P. An arduino is an expensive thing to dedicate to a task.

And even if we end up with more compact designs, thinking of it from the point of view of designing a shield would help gel what pins to use for what. In particular, one of the good points he has in the video is that you'd want a custom shield to be compatible with other standard shields such as the Ethernet or the Wi-Fi one so that they can work together.
