I am an embedded developer and have used a lot of different microcontrollers in the past and present. The RP2xxx series is a very exciting microcontroller series. Currently only the RP2040 exists, but I expect to see other versions with more ram, integrated flash, maybe a M4 instead of M0+ core.
The truely exciting things about the RP2040 are:
- Market availability
- Low price
- 2 x Cortex M0+ cores
- Possibility to overclock
- Flexible PIO Programmable State Machines with FIFOs
- High GPIO count
- Excellent documentation (!)
- Lots of examples
I think the RP2040 is even totally overpowered / underutilized for most of the tasks I see in most projects.
What I would love to see in the future, is a version with integrated flash (with possibility to expand with external QSPI flash), a cortex M4 core with FPU and the ability to attach PSRAM to expand the usable memory (and map it into the memory map of the RP2xxx).
