Prototyping

Learn the options for powering your LilyPad projects, LiPo battery safety and care, and how to calculate and consider power constraints on your projects.

The Single Supply Logic Converter allows you to bi-directionally translate signals from a 5V or 3.3V microcontroller without the need for a second power supply! The board provides an output for both 5V and 3.3V to power your sensors. It is equipped with a PTH resistor footprint for the option to adjust the voltage regulator on the low side of the TXB0104 for 2.5V or 1.8V devices.

This tutorial will show you how to assemble and use SparkFun's Variable Load board. It can be used to test stability of the power supply under various loads, battery lifetime, safety cutoffs, and other design elements of power supplies under test.
