Arduino UNO R4, I did you wait for the sticker ?

 

 

It's not a matter of drawing things over to guess if ? But apparently the Beagle Bone owning similar cousin of Renesas RA4M1, where this device is used to do RTOS. So akin to show more memory which is always a problem, the Espressif S3 mini is a 4 Mbit memory and probably, future of this uno r4 with a bit more of a memory ecu found in aliexpress and easy to craft can sustain eventually this board can be a cheap RTOS with few extras, I do think it's complete.

Seeing independently, I did not own the RA4M1 processor, but STM32F401CDU6 with a M4 , 384Kb rom, 96 Kb of memory , and a DSP, running at 84 Mhz, it's only the level 5V tolerant that is good for Renesas RA4M1.

But apparently owner of processor M4 does also own DPS internally and well set for suitable  I2S interfacing and apparently correct frequency sampling, and support to read like 22khz to 96 Khz which is surprising .

My recent acquisition is also the previous entry core ; similar to MKR, Wemos develop the SAMD21 version working at 3V3 it own also 256 kbit of development and more than one Analog port.  SAMD21 are M0 and or M0+, and come with a convenient DSP  .

 

No, I think it's complete, because  RA4M1, and many RISC-V processor are merging into Python so maybe this processor had friendly extension to allow the heavy weight of python fit into a 4Mb Expressif core exchanging the network card for python or putting it on the RA4M1 with adding through pin some memory . 

Personally I own 2 dead example of w600-pico being pure python interface, actually the development site of Allwinner pointing on Chinese website are like dead but the essential of the design in 1Mbit of memory it allow you to put down file in micro-python, it respond from internal ftp and WiFi setting being accessible through the boot ? I think the next exercise is talking to it in a i2c interface to see if it can share information... 

So that part sometimes is all which is mistaken in uno r4 if this one will do like some spaced version in Arduino world where they can do python on a chip and C++/LUA on the other, I think it can probably own a cheap version of python in case but every little chip owning lesser than 1mbit of memory are sometimes exempted from this task. 

 So they sell you out back into, the get back the 5V tolerance , bigger memory. I do say , than a SAMD21 padded with level voltage translation , TXB0106PWR still equivalent if it not coming with a battery of things. Arduino BLE, SENSE, have some extra like 6 or 9 DOF MEMS chip, some a micro ; I think Arduino will have to popularize I2S interface to be a easy way to manage directly the audio from an mp3 decoder or radio-chip, RDA5807 is particularly small and offer an I2S output to FM radio chip. 

 

 Tell us than Minima version owning a big 9V battery because it stand in size of the sticker ; what you holding under the sticker. But since our government show future in lithium and advanced battery to officially buy or built alternative. But battery in the retail portal haven't lower so fast since he announce it. So do people had ask about power rather than memory ?


By the way, actually in the retail market, there is so many error toward translation and uses of wrong to appeal to a better definition, I can joke a bit over it tell you, word "Being" should stand in the paper itself hiding you ... Nothing ; here the correction.

Does George Santos have receive money from Honest Gill.

 Back to five point of Honest Gill was :  76% of Americans say their representatives do a very bad job of listening to them. We used to aim big in this country – what happened? I’ll work hard to make sure 100% of Americans feel unrepresented.  I’ll make elections more representative for people who pay me. Ranked Choice Voting would disenfranchise campaign mega-donors and carelessly empower everyday Americans who don’t understand the wants and needs of the fundraising class. I’ll strengthen partisan gerry mandering. It’s better that politicians choose their voters, not the other way around, right ? Lobbyists spend $4 million per member of Congress. How are us poor Congress Members supposed to live on chump change? I pledge to continue to take gobs of cash from unscrupulous lobbyists. Just 4% of U.S. adults say the political system is working extremely or very well. Honest Gil will do his gosh darndest to get that number down to 0%.   To point 1, Honest Gil wi...

What are you doing here, another one ?

 Yeah, that's another one piece of Intel Corporation. Not in is box, already plugged somewhere. And now it's not sold with a board and not only wrap into a bubble bag. It come with the plastic box, and at least.    At 5.59$CA, if one of my board ares misconfiguration and lacking BIOS update to support higher than 10 Mb of memory, for family e5 2650v4 with 10 core rather than 14 and less than 20 Mb of L3 cache and will probably report only 60% of the memory is inaccessible rather than yelling for 66% of the memory if this one calculate the L3 memory as internal memory error for being unable to count the edge. Yes it's true an e5-2650 own 30Mb of L3 cache while the e5-2630 own 25 Mb. Ok it's not also the theoretical 2 cores in less. I seriously believe the second one will fail, for not having around 6 to 8 core and up to 15 Mb of memory on L3 cache. But apparently there is so many option withing the bios it let you disable the core. And mean I do request to investigate fo...

South Park Season 6 episode 8, Getting entry from everywhere, and talk that purge.

 Inside Red Hot Catholic love: Mostly engaged in a quest with old paper that compromise Vatican, we can empirically see the spider invade the Vatican as web that is origin of the sin and may compromise a story long of a big king willing to eat whole religion itself and there is drawn a idea the king will someday enter in the Vatican to invade it. But it's not the detailed reason, two other sub-talk from parent and delegation of believe do something strange among South Park resident.   Starting at the seventh minutes where Cartman challenge everyone. He not only winning but  got a slang talk to inherit from a strange symptoms against talk .     And manifestation of that symptoms lets people refluxing theirs 'expelation' back from the exit to normal way we are using to eat or express themselves.   We call it intro-digestion symptoms and beware of what you are doing it take you by surprise.  Accordingly to Stan report or Cartman slang to get a pooh out of...
