- All power input connectors are 2-pin Molex Micro Fit (with the correct GND/PWR orientation)
- Unless higher current is required, under special circumstances
- Easy attachment point for an oscilloscope probe GND - test points with the 'test point' part from digikey work well
- Make sure there are enough GND test points!
- Headers and pins for all communication protocols - for now, 0.1" headers, to standardize on a debug connector
- I2C
- SPI
- etc
...
- All components are labeled in a logical manner
- Maybe get someone else to look at it and make sure that they can follow the placement if any names had to be placed in weird orientations, etc.
- Connectors are labeled
- With function on top side (power input, CAN, Thermistor, etc.)
- With pinout on bottom side (or top side if possible)
- MSXIV Logo is on the board
- Correct board Rev is listed
- Pin 1 labeled on all ICs
- Ensure bottom silkscreen is mirrored
- Optional parts (such as CAN termination) is labeled
- Ensure all polarized components are labelled
- Double-check all of silkscreen in 3D mode
BOM
- Ensure that all parts are in the BOM, and have Supplier part numbers - ideally manufacturer part numbers as well
- Ensure the no components are ordered on tape and reel
- This just increases cost for no reason (since we don't have a pick and place machine)
- Digikey part numbers that end in DKR usually have tape and reel - watch out for them!

- Go to JLCPCB and upload the gerbers: https://jlcpcb.com/quote#/?orderType=1&stencilWidth=100&stencilLength=100&stencilCounts=5&stencilLayer=2&stencilPly=1.6&steelmeshSellingPriceRecordNum=A8256537-5522-491C-965C-646F5842AEC9&purchaseNumber=
- Make sure that JLC detects all layers and that the gerber viewer looks correct
- Upload the gerbers to the board sendouts page when available.
- Make sure the output files are in the GitHub branch and are well organized so that we can easily find the most recent rev
STEP File
- Make sure the STEP file is also generated, and in the correct location. Make sure whoever on Mech knows where the STEP file is so that enclosures, mounts can be designed for it.
- If having trouble opening the STEP file in Solidworks to verify that it is correct, see this thread: https://forum.solidworks.com/thread/223404
