Routing 100% Complete, +2 LEDs, +2 Resistors. Removed headers for the crystal as it may cause antenna effect and parasitic capacitance.
Routing Complete - Sanity check of PCB w/ someone else required, but DRC passes for now. 1x4 Header Pins *2 also added for debug, added to BoM.
Routing - General smaller components like inductors and USB done (Schematic shown, this part done on PCB)
Schematic First Revision
Schematic generally has been completed. However it is NOT double checked for mistakes.
Includes RPi Hardware Design with RP2350 Chapters:
- 2.1, 2.2 (Labeled as 2.1.1, will be fixed next rev), 2.2.1
- Chapter 3 NOT included as RP2354B has an integrated 2MB flash. Every pin but QSPI_SS (because of BOOTSEL) is No-Connected
- 4
- 5.1, 5.2, 5.3, 5.4
To do: Check w/ “Appendix B” for RP2350B-based designs, check entire chapters again, check for netmistakes, double check with someone else, PCB design according to the entire design manual, and add LCSC links to blank generic 0603 passives
Parts Selection
Specific Parts Researched and Linked (i.e. MCU, crystal), Passives Listed.
Done based off the RP2350 Hardware Design Guide at https://pip-assets.raspberrypi.com/categories/1214-rp2350/documents/RP-008280-DS-1-hardware-design-with-rp2350.pdf (from RPi)
