24v-5v stepdown converter to run ESP8266 & Motor controller

by Trillion on Tue May 07, 2019 5:11 pm

What we're trying to do
In the middle of learning to build a Huzzah/ESP8266-controlled solenoid.
The solenoids are non-latching, 24VDC
The 24VDC will be generated by a 110VAC - 24VDC adaptor that comes with the solenoid.

Questions
If we use a stepdown converter to get 5V power to the ESP8266 and Motor Controller from the 24V adaptor, is there any reason that wouldn't work?

Looking at the following, is there any reason one might be more or less appropriate for the job at hand?

I think any of them should work. You didn't specify which motor controller you are using. But assuming that the 5v is just for the logic side of the controller, 1A should be more than enough current for that and the ESP8266.

Thanks for the quick reply.

We're currently testing with two motor controllers, Dual H-Bridge Motor Driver for DC or Steppers - 600mA - L293D and DC Motor + Stepper FeatherWing Add-on For All Feather Boards

In the case of the Wing, you would want to power the wing with the 3.3v from the Huzzah. The Huzzah is a 3.3v processor and would not like to have 5v on the i2c bus.

If you are using the Feather version of the Huzzah, you just need to stack the Wing on it. The power connections will be automatic via the headers.
