They call it Dibond in the US, They use it in sign makingby NforcerOH - Reprappers
First off I'm not a control board designer but I'm thinking about a system, could we use more compact boards with less pins by using SPI/I2C to control steppers and read the inputs needed? It seems that if you remove the pin limitation on the atmega or the Due by taking advantage of the SPI/I2C buses you can control more sensors/devices. Why not use some ADS1115 for reading the temps and some CD7by NforcerOH - Experimental and Hobby
