Eggtimer TRS B2C/B4 Cream Gerbers
Note: This cream file includes the pads for the pre-mounted baro sensor, you’ll need to cut around it with an X-Acto knife. Also, the standard pads for the GPS module are included… the eight GND pads are smaller than the holes, so you won’t get any paste on the board there. Be VERY careful when you place the GPS module… the slightest knock will get it out of alignment, and due to its mass it won’t auto-align like smaller SMT parts do.

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.
