If you’re looking for an easy way to get a regulated 5 V for your electronics project, this battery holder from Bodhilabs is just what you need. It comes with a step-up DC-to-DC converter on the back that can provide up to 200 mA (typical; 500 mA max), and there is a jumper that can be removed to disconnect the batteries from the regulator and give you direct access to the battery voltage. We also sell the regulator PCB separately.
