ComputeModule 3+ DIY upgrade possible?

I have run out of space to install some scientific packages (SciPy, etc) that I need for a RevPi project. Would it be possible to upgrade the current 4GB ComputeModule with the new 32GB ComputeModule 3+ by just swapping the modules and installing the RevPi image?
Thanks in advance for a reply.

Controlling 3-way valves PWM DIO module

I have a RevPu Core 3, an AIO module and a DIO module. I would like to control 4 3-way valves using the DIO module. The valves need 24V to switch and 12V to hold. The switching current is ~180mA and the holding current is ~112mA. I have done some research and it seems that using the DIO modules in P...
