Rev. 3C

The 3C version of the SDBox design now released into the public domain.

SDBox design based on a Raspberry Pi Pico 2 W.

Changes in this release:

• Add push button to GPIO13 (Sunrom_Tactile_Switch_3x4x2mm_SMD_2-Pin)
• Remove JP1 and connect /RESET_3V3 directly to RUN
• Change to 0603 SMD LED diodes
• Change resistor values on R1,R2 to 1k Ohm
• Move J3 smd pad header to not interfere with USB-cable
• Bump revision to 3C

Please note, this new Rev 3C is untested but I'm pretty confident it'll work, there is only small changes in comparison to the former verified v3 version.

Gerbers attached.

Firmware can be built from source here, including a ftp server:
