Description: Replacement: None. We are no longer carrying this kit. This page is for reference only.
This kit was designed specifically for a high altitude balloon (HAB) project, but has many other uses. It was designed as a heater system for the electronics enclosure but you can use it to control a relay for other heating systems or wherever you might want to precisely control a relay.
This comes as an unassembled kit. It includes a pre-programmed ATmega328 and everything else you will need.
