The SparkFun Load Cell Amplifier is a small breakout board for the HX711 IC that allows you to easily read load cells to measure weight. By connecting the amplifier to your microcontroller you will be able to read the changes in the resistance of the load cell, and with some calibration you’ll be able to get very accurate weight measurements. This can be handy for creating your own industrial scale, process control or simple presence detection.

This is a simple coin cell battery holder that can enclose two CR2032 batteries inside itself, and kept closed via two phillips head screws. Each battery holder will run batteries in series, output up to 6V, and is equipped with an On/Off slide switch and two 6" power wires (one positive and one negative) on the back.

This 4xAA battery holder puts a nice finishing touch on your battery powered project. This holder features a removable, sliding cover, which is secured with a small phillips head screw. Another bonus is the ON/OFF switch which can be used to control power to your project.
