NEW GUIDE: Adafruit MAX17048 LiPoly / LiIon Fuel Gauge and Battery Monitor #AdafruitLearningSystem #Adafruit @adafruit @blitzcitydiy
The Adafruit MAX17048 LiPoly / LiIon Fuel Gauge and Battery Monitor connects to your Lipoly or LiIon battery and it will let you know the voltage of the cell and decodes the non-linear voltage to get you a valid percentage as well. To use, connect a 1S 3.7-4.2V Lithium Ion or Polymer battery to one of the JST 2 PH ports. Use the I2C interface and our Arduino or CircuitPython/Python library code to read the voltage and percentage whenever you like. There are various alerts, low power modes that can be customized as desired.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
