Powering 5V Devices from a Battery
Powering 5V Devices from a Battery
Problem
- Some devices such as servos and ultrasonic sensor require 5V to operate
- LiPo (lithium ion) batteries provide 3.7V so these devices might have enough power to operate correctly
- Note: generally the ultrasonic sensor will function with 3.7V if device power is connected to
Li+ in
Solution #1 - Use 5V USB Battery
- Any USB battery pack (like you would use to connect to your phone) with a USB A (the older, larger flat type) connecter should work
- Connect the battery pack to the Argon’s USB port and the Argon will now have 5V
- Connect your 5V devices to
GND and VUSB on the Argon
- Example: Power Bank
Solution #2 - Use a Step-Up 5V Voltage Regulator
