RP2040 vs RP2350 - or - Raspberry Pi Pico vs Raspberry Pi Pico 2

[@samcowley2010]

Thanks for the mention Tam, great comparison and review!

[@MrTamhan]

thank you, my friend. it is always a pleasure!

[@briantw99]

Great video, Tam!

[@MrTamhan]

Thank you, my friend!

[@MariusHeier1]

You also need an expensive inductor for the internal regulator.

[@MrTamhan]

thanks for talking back man!

I bought a Pimoroni RP2350B version ('Pico 2 Plus') - arriving the day after launch. First time I heard about 'Infineon' - but I managed to add a cheap 'Super Mini' ESP32C3 with ESP-AT for £1.50 which gives me a wireless connection via one of the Pico 2's UART. I think Adafruit have an ESP-AT SPI version.

[@MrTamhan]

Hi, thank you for talking back - I hope for DHL to clear my SeeedStudio PCB very soon. In the mean time - that is quite a neat combination. However, on the Pi Pico W, they did use an Infineon module instead...

[@MariusHeier1]

Great video. Probably the most informative one out so far. Do you think this chip was one of the reasons ARM wanted to buy them? To prevent them from continuing down the Risc-V path? This must been in the work from a lot of time.

[@MrTamhan]

Thank you so much for the praise. IMHO, the effort to 'me also' a RISCV design is not as high as one might think at first...

[@PaulGrayUK]

Fantastic, subbed.

[@MrTamhan]

Thank you, my friend. I am honoured by your trust

[@yrath5034]

Great presentation. I just wanted to point out that ARM or Arm is pronounced like the arm on the human body and the Pi in Raspberry Pi is like Apple Pie.

[@MrTamhan]

Thanks man. Sadly, my English is a learned language. But I will try to keep it in mind!!!

[@FrantisekBorsik]

Them Uptonites are crazy :)

[@MrTamhan]

yes man. but capitalism does push them to work, sometimes...

[@FrantisekBorsik]

@@MrTamhan true that

[@MrTamhan]

Only way to do it, man

[@freepoet6737]

Pimeroni do have a number of Pico 2 boards available right now, and at least one with larger packaged RP2035B.

[@freepoet6737]

Oops, seems the Pimoroni Pico Plus 2 has sold out already!

[@jonmraptor3440]

@@freepoet6737 They still have the PGA2350 with RP2350B!

[@MrTamhan]

Thanks for talking back man. But I just printed out the DHL forms for the Seeed Studio board. Hope to get it next week

[@MrTamhan]

Yes man, looks like the Uptonites did a pretty good job supplying the MCU chips to their board houses. Kudos to that!

[@jonmraptor3440]

@@MrTamhanagreed lol. I do have a question though about why you dislike pi foundation and upton? I am not trying to be critical of you, but it seems like you dislike them, so there must be a reason why. I do have to say I am not a big fan of becoming more reliant on Chinese tech for applications, where there is a risk of a motivated state actor (ccp) from doing some shenanigans, which is the only reason I somewhat support raspberry pi in my mind, but if they are bad, I would like to be informed:)

[@GizellaCseh]

Congratulation!

[@MrTamhan]

Thank you! I am very happy to see you enjoy the channel!

[@pjaro77]

i hope the wifi/bluetooth version will include IEEE 802.15.4-2006 and BLE with zephyr OS support to make an openthread device.

[@MrTamhan]

Hello, sorry for being very slow in responding to you. IMHO, it should at least have BLE and Zephyr - for Thread, I am not sure to be honest as it depends on the module from Infineon which they will use. But I can ask for you!

[@john_hind]

Weird way to support RISC-V Uptonites! Having it in the same chip as ARM cores, presumably means they have to pay the ARM licence even if the user has no intention of using the ARM cores. Also it means the chip area is unnecessarily large whichever core type you choose. Since chip cost is pretty much proportional to area, this will push cost up for both core types!

[@MrTamhan]

Hello, thank you for talking back! The thing here is that, according to rumors, if the pressure is large enough, the licence fee becomes infertesimally small. And you must always remember that Upton actually is a BroadCom man, not an RPi man. So there might always be a side benefit.

[@jamesh9756]

@@MrTamhan Eben Upton is DEFINITELY a Raspberry Pi Man given he founded the company and remains in charge after the IPO. Nothing to do with Brcm. Also, the RISC cores on the RP2350 are tiny, and take up very little die area.

[@MrTamhan]

@@jamesh9756 Hello, thank you. Are you sure that he completely lost his connection to BCM after the IPO?

[@jamesh9756]

@@MrTamhan He left Broadcom years ago IIRC and has been working full-time at RPi since. The company uses Brcm SoCs so clearly there is a working relationship, just like any company and chip vendor.

Quality in pi 5 was terrible. Flimsy nvme ribbon is a joke, minuscule micro hdmi plugs. First pi 5 died in a fortnight, I got a refund but was still out of pocket with the shipping.

[@MrTamhan]

Hi Man, thank you so much for talking back! May I ask which distributor left you hanging in the dry?

[@1toneboy]

@@MrTamhan I wouldn't say they left me high and dry, although they made me re-test it with about 6 different power supplies, then made me post it back for them to confirm. Before they sent me a replacement. I did ask for a replacement thermal pad for the fan and they said 'sorry, no'. Maybe if I argued a refund with the $12AUD postage they would have refunded it, but I'd already wasted so much time and I don't think they're a big company so I didn't. It was more the week's emailing back and forth which was the main irritation. I was more irritated with the Pi Foundation for the failure, because if it failed a year later I would have been out of pocket with no replacement. When I buy something I expect it to last. Anyway to answer your question it was Core Electronics.

[@MrTamhan]

Hi, oh man, I know this one too well. This is kind of annoying, yes, when the reclaiming of the small things is blocked iontentionally...
