Brief overview of competition tasks
Last term the plan was to land on the barrel
At the end of term flight test, we realized the tuning is not reliable enough for this and if the drone clips the barrel, its ggs
Now we will be doing a winch that lowers the pump
A new pump is needed, servo will likely be controlled by Pixhawk. Worst case we do an single servo driver
1-2 servos needed
If someone wants to help with this you are welcome

Jerry demoed TinyCAD for harness diagrams, we are on board
- Kenny Na to begin work on diagram this weekend hopefully
- Going off of new system diagram Jerry made
- Using the XT60 2+4 connectors
Need to order XT60 2+4 connectors so they get here early Feb ideally
- Ryan Scomazzon on getting the best shipping times
12V -> 5V @ 4A Buck Converter + ELRS Receiver board 1 & 3 not working, board 2 link drops
- Need to order extra SX1281 RF IC & U.FL connectors to diagnose if it was an assembly issue
  - booting up without an antenna connected may have killed LNA due to high-Z power reflection
    - there was no firmware when I did this on accident, but it’s still possible…
- Otherwise out of ideas on this one… try different antennas? 😞

In order of priority. These are the active design projects.

Thanks for final board review Meghan Dang!
Gerbers uploaded to JLCPCB cart, thanks Santosh Erathasari
DigiKey component order coming soon, may order modem + extras early
- Note to self: we’ve already ordered the major buck ICs and the STM32
