!! WORK IN PROGRESS !!
I restarted changes to revB1 on 04/2024 with the following goals:
- fix remaining issues (SDC power, ESD, see below)
- optimize for machine assembly
To-Be-Done changes from rev.A1 to rev.B1
- add power switch for SDC +3.3V, add digital lines disconnect
- probably AP2191D ?
- change ESD protection
- change decoupling caps
- move speaker connector
- ...??? see pdf
Implemented changes from rev.A1 to rev.B1
- change green LED resistors to 2k7 (although this depends on LED).
- Remove D504 (USB ESD): the SP0503 is not suitable!
- Add 5V and +3.3V pins to J601 internal mem.bus connector.
- Changed AURA FPGA footprint to the smaller EP pad (now the footprint is the same as VERA)

Questions
How big is the X65-sbc revB1 PCB?
It measures 100 × 180 mm and has 4 copper layers, 1.6 mm thick.
What parts does the X65-sbc revB1 use?
344 parts, built around the ICE40UP5K-SG48ITR50, ICE40HX4K-TQ144, 74LVC2G17DBVR-TD and W25Q16JVSNIQ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the X65-sbc revB1 KiCad files?
From the jsyk/x65 repository on GitHub, at the commit this page was made from: the board is pcb/x65-sbc-revB1/x65-sbc-revB1.kicad_pcb and its schematic pcb/x65-sbc-revA1/02-cpu_sram.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the X65-sbc revB1 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
