In the past we have been using various boards from Adafruit and Sparkfun to teach students about the interaction between a Raspberry Pi and various sensors.
We've recently come across something very interesting, namely "Embeddio SNAP Boards" which as they advertise, offer the same features but more advantages. The students used a lot of wires in the past which was unnecessary in my opinion, this seems to solve it.
We may even let the students make their own boards in the future.
Anyone have some advice to enhance the practical learning curve of the students?
