Faraday is capable of operating with an external battery between 4.5V and 17V. This cable provides easy connection between Faraday and a standard 9V battery. Free Faraday from USB power by using this pre-made cable.
Without any optimizations for power use, Faraday has obtained roughly 9 hours of operation at 400mW output with 1Hz transmissions using a 9V battery. We documented this with our balloon flight. In the future we will optimize for better battery life.
