Question: are we gonna use the GPS listed here? https://uwarg-docs.atlassian.net/wiki/spaces/ARCHS22/pages/2556133415/Fixed+Wing+2025#Electrical-Components In the old (Jun 2024) block digram, it’s connected to the CAN splitter but It doesn’t seem to support CAN?
M9N GPS… Jerry Tian will verify with Daniel or Nathan regarding CAN capability
How many pitot tubes do we need? where do we want it to be placed at?
just 1, will be placed halfway down the spar of the left wing
Harness timeline
Jerry Tian will host a session to familiarise more EE members with this
Tentativephysical harness done by Feb 23
6s Servo Module (EFS)
STATUS?
EFS: Hardy Yu PMing this, an onsite member was assigned to this yesterday so Hardy met with them today. No official progress on the task since last week but still on schedule since there isn’t too much left to do for this task. I believe Hardy found a possible work around to the external crystal oscillator issue but maybe he can update on that.
EE: to assemble rev 2 PCB
6s power module (EFS)
STATUS? (last week said we would set due date)
Research around the sensor/datasheet etc is finished. Began driver dev now. The CAN component will be very quick to implement since it’s very similar to our other CAN projects but don’t have a great estimate on how long driver part will take as it’s a capable member working on it but it’s his first driver. Open to due date suggestions or range and we can try to push it to be completed by then. Maybe Derek Tang has a better estimate in mind
EE to finalize and order connectors
follow up in next eclipse sync
Timeline
Foam Plane Pilot Training (first flight): Feb 2
Ecplise Strapdown Test: March 1st/2nd
Eclipse Maiden Flight Test: March 8th/9th
...
Mechanical structure is done, just need to mount electronics (this will hopefully change before tuesday meeting)
Validated the electronics
Mounted everything other than the rudder servo
Need to figure out link quality issues with our ELRS board
Kenny Na will come to foam plane work session next week Monday to check in on this
might happen due to automatic RF signalling upon bootup and the signal is reflected back from an empty u.fl/antenna connector destroying the LNA output on the SX1281 RF IC
will be ordering some parts from digikey to repair old board
if unable to get reliable signal link quality will use the over the counter ELRS board we have 😞
