The v1.3 files are production ready! The pre production boards just came in and they work really well.
New changes in this final version:
- Improved routing and buck converter layout
- A length-matching on the GPIO connector
- Better decoupling for SDRAM just to be safe
- TVS diode on the UTIL and HPD line of the GPIO to prevent the ECP5 from getting hit with 5V
- Cosmetic changes
- CE and UKCA marks
Attached is all the files needed for production:
- bom.csv is formatted for JLCPCB, while bom.xlsx is for elecrow
- positions.csv is for JLC, icepi-zero-pnp.zip for elecrow
- Icepi_Zero_v1.3_gerbers.zip is for both
But if you want to get your own, get one from https://www.crowdsupply.com/icy-electronics/icepi-zero/!
It'll probably be a lot cheaper than a low volume batch :)
