Welcome to Garbee and Garbee, home to Altus Metrum and other fine products! See https://altusmetrum.org for product details, software, and documentation.
EasyMega is identical to TeleMega, but without the integrated GPS and telemetry link. This makes EasyMega an ideal choice for complex projects including sustainers on multi-stage projects where integrated radio functionality isn’t needed. 4 of the 6 pyro events are configurable and can be based on time and various flight events and status, including angle from vertical.
Please note that this board requires a 1S LiPo battery with appropriate JST connector for operation. To ensure proper voltage and polarity, and to avoid unexpected resets during pyro events, we strongly suggest you buy an Altus Metrum battery for use with EasyMega!
