Active PCB Projects
Drone Harness (Neel)
@Neel Patel
VTX and OSD harness redo almost done
High Current Power Module (Taim)
@Taim Al-Dabbagh
license finally works yayyy
taim working on it rn
just need to test thermal performance in the simulation before ordering the pcb
Battery Elimination Circuit (Ishman)
@Ishman Mann
chose a new buck controller
selecting the switching FETs
12S ESC (Mena)
@Mena Azab
No updates, busy again at work.
6S ESC (Rayyan, Mostafa)
@Rayyan Mahmood @Mostafa Hussein
Rayyan: Halfway done Gate Driver Schematic
Need some help with correcting footprint
LED Controller (Neel, Parker)
@Neel Patel @Parker Lawrence-Valeriani
No new updates due to busy work week
PDB (Tom)
@Tom Chiu
Tracking Antenna (Nolan, Hardy, Michael)
@Nolan Haines @Hardy Yu @Michael Botros
ZP3 Rework (Anthony, Ryan)
@Anthony Zhelnakov @Ryan Scomazzon
@Daniel Puratich why do the ground pin pads on the two board to board connector have one via on the left and one via on the right? Is it for balancing the copper?
Redundant Diversity ELRS , RF project
@Nolan Haines
5V-24V Boost Board
@Allan Liu
Talked to previous project owner, board is supposed to be used as variable voltage power supply for field testing. Multiple outputs is fine instead of one variable one as long as it’s properly labelled.
New Projects
Project | Link | Description | Needs Assessment |
|---|---|---|---|
Houston harness schematic | https://uwarg-docs.atlassian.net/wiki/spaces/ARCHS22/pages/2296512610 | Draw houston schematic from scratch. We want a schematic for all possible power + sensor harnesses so that we can quickly build/grab harness for flight test | Wiring is too messy as of Feb 13, 2024. Also sensor harness is gonna be different for different flight tests
|
Pegasus harness schematic | https://warg.365.altium.com/designs/EE4130C4-749C-446F-8B89-B208A6919071 | reorganize into hierarchical structure (see 12S servo module example) Label length, color, wire gauge | the schematic as of now is a bit hard to read |
12S ESC | https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2250670083 | Mena needs help ;d | see confluence page |
CAN Interface | https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2311684143 |
| project on hold rn |
ICM 42688 breakout | Could get fancy using CAN bus w/it later but for now just breaking out SPI, and maybe having an onboard voltage regulator or smth (better perf). | EFS is looking to move from bmx160's to ICM 42688's . These are used commonly on all sorts of drones and fc's (probaly the most popular drone IMU being sold new right now). They're about 2$ for a chip, can be pick/placed by JLCPCB, but the eval kits are 58$. | |
Smoke stopper | Analog design. Switch between different efuses (e.g. 1A, 2A, 3A) | The board limits current flowing through when we run the motor test. It protects downstream electronic devices. It also prevents drawing too much current from the batteries.
leads need to decide whether we want a MCU on the PCB |
