Raspberry Pi Pico 2 | Everything You Need To Know

Raspberry Pi has just announced the Pico 2, the successor in their line of affordable microcontrollers. The original Pico was a great addition to the maker world and in this video, we are going to see what this next generation brings and what it means for the maker community, and boy are things looking promising; better hardware, new security features, and a RISC-V processor?

There is an official statement regarding the Pico W 2: available by the end of the year, same RF chip.

The big thing for me is DSP instructions. With DMA, 150MHz (likely more if you overclock it), 520kB RAM, and I2S, this chip looks perfect for live audio and radio data processing.

my suspicion: you can't get the 4 cores to run in parallel because there are no 4 cores. they just have different instruction decoders that use the same ALU. that would mean you have two cores but inside a core you have different components, one being the instruction decoder. and you put two different instruction decoders inside the core.
also adding more and more cores does not scale up that well because they have to share the same memory bus. with two cores it is easier, because while one core is calculating, the other core is accessing the memory bus. with more cores and DMAs running, you need separate cache blocks to optimize memory access. that is expensive.

I'm here for the first time and I really like the show and information. Hope to see more in the future ;)

[MarcusPocus]

still no RESET button and USB-C plug!!!

[philoffhistree]

very nice i was just about to patent a device that uses the pico, now i can also lock the software up inside it too

[artisticyeti]

I wonder how much better the pico series will become. I personally use the pico in each of my projects. Imagine the pico 3 or pico 4 having quad core or even octa core with microcontroller level power consumption!!!!

There is absolutely nothing remotely ridiculous about the formula and it works out to an even number by design (leaving out any extra special purpose memory such as dual port USB buffers which I am guessing is how you get from 512K to 520K). Memory usually comes in powers of 2, 16K, 32K, 64K, 256K, 512K, etc. so log2 makes perfect sense, it is log2(2^x) = x. Thus by taking log2 you are just giving the exponent. And linear multiples would quickly blow through a one digit value:1, 2, 4, 8, oops while log2() gives 10 different sizes you might actually use. And by dividing by 16K, they don't waste values on small sizes they would never make and leave more for big sizes. Besides, log2(16384) is already 14, which is more than one digit. Another way to express it is ram=2^(x+14). Or just start at 16K and double it the number of times specified in the digit.

Uh-h-h, M33 cores... FPU, maybe? It sounds like an amazing digital controller for a switching power supply.

[norazmanothman]

USB type B or C, it comes down to cost saving and supply chain.

[TheWhitde]

I still like the Waveshare ESP32 S3 Pico I got from Core Electronics. 240Mhz, efficient, PSRAM, wifi bluetooth, etc ... and AU$15ish

[CamArt]

Can not compete with the ESP32, for $6 you get the same memory plus USB C, wifi and bluetooth.

[theelmonk]

Is it still 12Mb/s USB or has it upgraded to USB 2.0 at 480Mb/s ?
Does the ADC work properly now ?

[itzmetanjim]

1:11 if they make a new RP chip with a small update (same no.of cores, same type of cores, ram is not at least double previous, non-volatile memory is not at least double previous), they can't release it as it will have the same name.

[rtos]

The wireless model would be a great addition

[BlackHoleForge]

I don't mind that it doesn't have usb-c. I still use OTG cables for peripherals. So it's beneficial to me.

[BBme]

1 usd is a lot for a low cost board. you have to learn more on cost senses. the reset an usbc are only cents.

[KNfLrPn]

Can't wait for the third-party boards with USB-C and reset button. I stopped using the original Pico immediately because of those two things.

[freepoet]

Maybe the RiscV is there to queer the pitch of the other micro-controller chip manufacturers, why buy their products, if the Pico has it thrown in!

[TahaHussain-ch]

Can u please make a video on how to get breadboard os onto the rpi pico
