Connecting Power supplies in parallel - Arduino Forum
Feb 15, 2022 · Connecting the supplies to opposite ends of the combined strip (or rather the supply cable running alongside the strip to bridge in power every 50 or so LEDs) will generally avoid this. So it is safer to separate the positive rails.
FAQ: How to use two power supplies. - Tutorials - Arduino Forum
Nov 11, 2019 · two power supplies for two Arduino, which communicated to each other (via I2C, UART, SPI...) 2. How To It's very simple, just connect GND from one to the other. Example: This post showed a wiring diagram for using the extra power supply for multiple servo motors.

Jul 7, 2011 · I need to connect together two power supplies in parallel for more current output. The power supplies are XP Power: ECM40US09, they are rated at 9V 4.5Amps. If someone could check them out and give me a heads up would be great!
Combining 5V power supplies in parallel to obtain more current
Feb 2, 2020 · I'm working with off the shelf 10A supplies, so technically I can power them all by combining two 10A supplies. I read that by protecting the 5V DC output from each supply with a reverse bias diode, I can connect them on the output side in parallel to achieve 20A.
Two arduinos one power source - Arduino Stack Exchange
Feb 25, 2016 · How can one power two arduinos using the same power source? Such that the first is connected by barrel jack to a 12v transformer. I saw this youtube video which very briefly mentions doing this by make the connections: This surprised me as I was not aware the 5V could operate as a power input.
Using External power suppplies with Arduino explained!
Apr 3, 2021 · Well, today I'll show how to correctly use external power supply with Arduino! Is Really simple, You will see: Well, power supplies are used for every projects with Arduinos, like controlling Leds, Servo motors, Relays and more!
power - Is it reasonable to use two LDOs in parallel for …
Dec 15, 2022 · I want to use two LDOs in parallel before an OR-controller (specifically, an LM66100-Q1.) One LDO is enough to feed the system, so it will not be overloaded. If one LDO fails, or one LDO has a short circuit, fuse burns and the other LDO can supply the system.
