I spent some of today reviewing AVR assembly language so that I could write motor control firmware for a small four wheeled robot.
I thought about using a Raspberry Pi Zero W. However, every time I've tried to use a Zero W for a project, the Pi became unstable at some point during normal operation and caused erratic circuit behavior. So, I think this time, I'm going to use the Zero W for upper level sensor processing and have the lower level control system running on more reliable microcontrollers.
Well... we'll see how it all goes.
Did you get a specific error? Have you tried a Raspberry pi 2/3 to see if it is just a zero not being powerful enough then scaling down to a Pi Zero for deployment?

For all my experiments the Pi is isolated via either transistors or opto-isolators. So, there's no problem with the external circuitry loading down the power supply for the Pi. I've used various Pi modules over the last several years.
There are definitely stability issues with each model. The most annoying problem I've encountered is finicky networking. A common symptom is showing a connection as active, but the unit is inaccessible via other network hosts. I've answered several of these questions myself on StackExchange.
Unfortunately, StackExchange doesn't hand out STEEM for upvotes.... Perhaps someone will re-create a technical Q/A through STEEM Engine. Then I could enjoy some financial rewards instead of a few 1000 "points" and a good feeling.
In my experience, the Pi is not suitable as a critical component in a project's system architecture... it's best not to rely on it to be fully functional 24/7.
