Raspberry Pi RP2350

“the RP2350 itself had its protection defeated by fault injection”

“RP2350 doesn't have a DAC or Comparator.”

“The RP2350 just adds some bog-standard security features the ESP32 family and plenty of others have had for ages”

“ESP32 and RP2350 have pretty crap or nearly non-existent analog.”

“far less effort these days, and give much better value”

“They had a bounty when it launched to find similar vulnerabilities and they worked to patch the ones that were found.”

“Because it's inexpensive and not designed to be tamper-resistant.”

“The RP2350's secure enclave made it particularly attractive for use as a Yubikey alternative.”

“some very useful (and somewhat unusual) features in its PIO blocks”

“It costs a fraction of the competition and you can use just about any pin for anything you want!”

“The RP2350 is probably the most underrated microcontroller available today.”

“Achieving generation time of just 5s is pretty impressive on this hardware.”

“The RP2000 series is quite disappointing IO-wise: no timers, barely any ADC, no touch sensors, no CAN”

“never underestimate the power of controlling the whole pipeline”

“you can actually buy the raw RP2040 or RP2350 chips (for roughly $1) and make your own custom PCB”

“the only memory-mapped QSPI unit I've encountered so far that I've not been able to crash or hang”

“I'm sure you can ask Claude to vibe code something on RP2350 nowadays”

“the RP2350 is a bit more BOM-friendly, imho”

“If you need a programmable IO state machine (or twelve) then you need the RP2350, period.”

“an RP2350 or ESP32 is probably better for anything embedded or battery powered”

“PIO, high-quality datasheet, nice ecosystem, etc.”

“5v tolerant IO if set up correctly, enough GPIO's and the PIO's to trigger everything at once, and more than enough speed to emulate flash.”

“would strongly prefer open hardware like the RP2XXX family over a commercial chip like the ESP”

“RP2350 has a hardware FPU and much more processing capability, so supports more channels and filters”

“The ADCs on RP2040/2350 only have 12 bit resolution.”

“RP2350 is capable of reading IOs at 400Mbps”

“you wont have any performance problems like with 200MHz pic. Downside is lack of usb 2.0”

“PIO units may be tricky to configure, but they're incredibly versatile.”

“Both the RP2040 and the RP2350 are amazing value these days”

“It's honestly surprising how robust the RP2350 was under such extreme experimentation”

“would dominate the Z80 in literally every way”

“The new RP 2350 has an enhanced PIO that relaxes some of the constraints the author ran into here.”

“has lots of nifty support libraries available, and will definitely do better than the teensy 3.2”

“I wish I could buy RP2350 with the ARM cores being hard-fused disabled, "cheaper" since no ARM royalties would have to be paid.”

“I'm transitioning to rp2350 as it's just better suited for that kind of work, easier to find and cheaper.”

“It has very few RAM to emulate PC's/higher end Classic Macs.”

“If the RP peripherals meet your needs I agree that's a great value”

“With a similarly priced (sometimes cheaper) platform like the amazing rp2040 / rp2350 which is roughly 100 times more powerful”

“It doesn't come close to being able to do interesting things like LVDS ADCs or actual high speed memory interfaces because of the bit width requirement”

“some of those shortcomings have already been addressed in rp2350, with double sram (520KB at this price point!)”
