Either Xbee or RFD900

XBEE:

The xbee itself is pretty small, but it usually go along with an interface board that has similar size as xbee itself

RFD900:

It usually go along with two antennas attached to it.

Custom 5V buck converter

The custom 5v buck converter made from EE team

Notice that this buck is only graded for 2A

So maybe consider adding another buck just for the servo power supply?

Prototype Board/Nucleo Shield

Prototype Board:

A integration component which connects different electronic peripherials.

Notice this is the temporary solution for the first revision of tracking antenna

Nucleo Shield:

A delegated PCB design to attached to the Nucleo L5 to extend the connectively and functionality for antenna tower power and electronic system

Confluence Doc: Tracking Antenna Initial Concept W23

Prototype Board user instruction: How to use the Tracking Antenna Prototype Board

Nucleo Shield PCB Design Doc: Tracking Antenna Nucleo Shield Design

@Hardy Yu

Nucleo L5

Stm32 processor with tracking antenna algorithm firmware in it

*Very New*

EE and Firmware decided they want to switch back from f401 to l5 as the development board

Making part is tricky

Jigs

Cannot make it on our brake

• buy quarter inch plate from machine shop and waterjet the cutout

• could move in mounting holes

• Move in the bolts close to the base

• 14 gage sheet metal

• buy 14 gage

• google 1552 aluminum gage table

Baseplate

• make it similar to the drone

• can mount or put Velcro

• 30 by 30 m3 grid

• do both, mounting holes and Velcro

• just need the holes

Press fit bearing

• 2 thou under

• waterjet is negligible but could be

Standoff

• Fillet

3D printing

• Might do multiple 3D prints to find out tolerancing

• Hex broch

• more than 25cm, further is better

Order Parts

• Can order the stuff online

• fix stuff and then order aluminum

• make a pr (procurement)

• Follow instructions in purchase protocol

• Linked in discord/info/wargclicklinks/internalpurchaseprotocol

• search confluence for this in ops space

• ops space home should be the first one

• Hex shaft should be charged with smiles order from EMS

• We have enough Velcro

• Caster wheels

Fasteners

• Don't get plain steel

• black steel fasteners
