Lost some footprint associations, but also changed some footprints to use alternative components from LCSC
Replace footprint associations with JST PH through hole right angle connectors and add associated LCSC part no (optimized for price and availability).
Used smaller buttons. Added custom footprint. JST PH 2.0 thru-hole right angle connectors. Connected USB 5v via diode to 3v3 regulator. Silkscreen updated.
Moved buttons, sdcard and usb chip around
Had to move connectors around to make room.
I wanted to be sure I didn't delete something I needed later, so this commit is all files in whatever state. In the next commit I will remove everything I think I no longer need so the repo is a bit cleaner and easier to see what files are important.
Version B1 with embedded ESP32 USB C with CH340C chip Reset and boot buttons E-Stop and JST PH 2.00mm connectors
Rev B was using an old and incorrect footprint causing a 3.3v short to ground when an SD card was inserted. Update to use the fixed footprint. Added pull-up resistors for EN and IO0 (Boot mode). On test board, IO0 appeared to be pulled permanently low. It could be programmed but would not boot. It may only be necessary for EN to be pulled high but added the pull-up for IO0 just incase.
Added pull-ups for EN, Bpot, X_Limit & Y_Limit. Re-routed some tracks to improve thermal ground on ESP32 module and to allow for better Gnd fills. Regenerated Gerber files to include footprint values on front silkscreen.
Fixed broken paths.
…ter_Controller into embedded-esp32
Some 10k resistors were using the value 10k vs 10K so weren't grouped correctly. Some 100nF capacitors were shown as 0.1uF so weren't grouped correctly.
…ter_Controller into embedded-esp32
Decoupling cap for ESP32 would be in the way of an M3 screw head. Moved down to nearer J17. Clearance checked in CAD.
220uF is more readily available from LCSC and can use a better quality capacitor
Merge Embedded esp32 branch into main
Update gerber files
GND and En pins were swapped on diagram. Fixed in this version
