![]() My plan was to have 12v input supplying the solenoid, VIN on the IoT33 as well as supply power to the AMS1117. If anyone can confirm that would be great. ![]() Rotary encoder - says 5v on package, but I've heard people say they work fine on 3v3. LCD 2004 - 5v for LCD - A4/A5 for SDA/SLA ![]() The specs on the devices I am working with are the following I was planning to have a AMS1117 (capacitors includes as per the data sheet) for steady 5v supply. I have read that the 5V on the Nano IoT33 isn't the best, so a separate voltage converter is better to get 5v. I haven't mapped out the schematics yet in Fritzing yet, as I want to make sure I'm going down the right path first. I'm now trying to prototype using a Nano IoT 33 instead, so I can get it connected up to a MQQT platform (Cayenne) and need some help managing different power supplies. I have already made a control unit off a Nano that controls a 12v solenoid with a TIP120 (flyback diode included) as well as some ancillary components like a float switch, a push button rotary encoder and an 2004 LCD that is working well. I'm pretty new to custom PCB's, but learning.
