Episode notes
Why He Chose The RP2040
- Alex chose the RP2040 because its documentation and design guides are excellent.
- Good datasheets made wiring USB and power trivial compared to older chips.
Follow Datasheet Placement Rules
- Follow chip datasheet recommendations: place USB series resistors close to the microcontroller.
- Small recommended parts (33Ω, etc.) fix reflections and improve signal integrity.
Put The Debug Header Near The CPU
- Place debug/programming headers close to the CPU to reduce trace length and reflections.
- A short SWD connection speeds up debugging and improves reliability.
