This board is a compact (0.5″ × 0.9″) breakout board for ST’s L3GD20 three-axis digital-output gyroscope; we therefore recommend careful reading of theL3GD20 datasheet (2MB pdf) before using this product.
This extremely compact boost regulator generates 5 V from voltages as low as 0.8 V and delivers up to 200 mA, making it perfect for powering small 5V electronics projects from 1 to 3 NiMH, NiCd, or alkaline cells or from a single lithium-ion cell.
This 5 V boost (step-up) voltage regulator generates higher output voltages from input voltages as low as 0.5 V, and it also automatically switches to a linear down-regulation mode when the input voltage exceeds the output.
The compact module allows any microcontroller or computer with a serial port (external RS-232 level converter required) or USB-to-serial adapter to easily drive two small, brushed DC motors with full direction and speed control.
The Pololu adjustable boost regulator is a very flexible switching regulator (also called a switched-mode power supply, SMPS, or DC-to-DC converter) that can generate voltages higher than its input voltage.
