Eggtimer Quasar Support
See the Eggtimer Quasar User’s Guide for instructions on how to update the firmware.
Note: We generally do not post older versions of the firmware, unless there is an incompatibility with the currently-shipping version of the hardware. We recommend that you check our site regularly for firmware updates, and update your firmware to the latest release if applicable.
IMPORTANT NOTE: DO NOT try to perform a firmware update with any loads attached to the deployment outputs! Although the chance of them firing during an update is virtually zero, it’s very bad safety practice to have any pyrotechnic loads connected to an altimeter when the rocket is not being prepped for flight.
