Power Chip with 3 AAA Battery Pack

New for 2026 is our Crazy Circuits Power Chip with AAA Battery pack! This part replaces our CR2032 Coin Cell Battery Chip in all our kits. This component connects a 2 AA or 2 AAA battery pack to the Crazy Circuits system. To help with building projects, we've added in two requested features! First, a small status LED shows when power is flowing to the system. Second, we've built in Short Circuit protection. If a short is present in your circuit the status LED will turn off and power will stop flowing to your project. This prevents batteries from wearing our or getting uncomfortably hot.
