SparkFun LiPo Fuel Gauge

LiPo batteries are a great way to power your projects. They're small, lightweight, and pack a good punch for their size. Unfortunately, even the best batteries eventually run low on power, and when they do it's often unexpected (and at the worst time). Don't be caught by surprise next time your board suddenly powers down!

The SparkFun LiPo Fuel Gauge connects your battery to your project and uses a sophisticated algorithm to detect the relative state of charge and direct A/D measurement of battery voltage. In other words, it tells your microcontroller how much 'fuel' is left in the tank. The LiPo Fuel Gauge communicates with your project over I2C and an alert pin also tells you when the charge has dropped below a certain percentage.

  • Fuel gauge system for single-cell lithium-ion batteries
  • Can be connected in circuit to monitor the battery.
  • Hardware and Software Reset.
  • I2C Interface

Wireless Joystick Hookup Guide

January 5, 2017

A hookup guide for the SparkFun Wireless Joystick Kit.

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.
