Run laptop off AC power without charging battery
Some laptops may not be as well-behaved when you do this, with reduced performance when the battery is removed especially if the AC adapter can''t supply enough power for full-load operation (such as when gaming). While neither of my laptops do this, this is worth noting. Be sure to put the battery back in before you unplug, though!
I have read that running an external battery with the internal …
The problem is your power supply and it''s a common issue. Most power supplies actually will output the required 5V 2.4A power that the GoPro needs, however they don''t report their output properly due to built in current protection, overcharge protection etc. So when the GoPro does a power requirement check, your power supply underreports what it''s …
How to Power the Raspberry Pi Pico

Power supply for Seeeduino Xiao
They only power on using a 5V input applied to pins 5V and GND. The test rig was a bench DC power supply. The XIAO ESP32C3 seems to power on as low as 4.1V DC applied to the 5V pin. No external component is required, just a direct connection from the bench power supply to the 5V pin. Therefore the posts somewhere on the internet about needing a ...

STM32F429I-DISC1 board external power supply
I''m planning to power the board up via external power supply. After looking at its schematic diagram, I found that one can supply power through 5V pin or 3V pin on the headers. But I wonder if you could have problem, when you would connect this board to 5V external power supply and PC also.
Adding external power supply to any arduino connected component
I have an Arduino Pro Mini 3.3v and the voltage is too small for my buzzer to ring loudly. I want to add a 9v battery to power the buzzer. This is my current circuit: Arduino (pin 9) => Buzzer +ve Arduino Gnd => Buzzer -ve. I want to power the buzzer using an external 9v battery but I have no idea how to implement it in the circuit. All I know ...
3.3V external power supply
Hi everyone, I need to power my F401RE with a 3.3V external power source. I read in the datasheet I need to connect the power source to the CN7 pin 12 or CN7 pin 16. Where do I connect GND signal apart from 3.3V signal? Also, from what I understood, I need to desolder SB2 AND SB12 to get it working, to mantain the ST-LINK functionalities.
How do I connect the STM32F4 Discovery to external power?
For the STM32F4 Discovery board, can someone tell me exactly what pins need to be connected in order to power this externally (i.e. not via USB)? Surprisinginly, I can''t find any place where this information is clearly stated. I''m assuming that I need to connect 5V and ground. But do I need to supply 5V on both 5V pins, or just one of them? Do ...

Yaesu: Yaesu FT3D/FT5D external power supply while battery …
Running this off a wall-wart for transmitting is not a good idea unless you key up very sporadically. I''d find a suitable adjustable voltage power supply set to 10.5 VDC with at least 2-3 amps of current capacity, and also keep in mind keying up a portable may cause RF to get back into the power supply unless you''re running an external antenna.
