The Raspberry Pi (Single-Board Computer) Thread

NanoPi K1 Plus: A $35 Raspberry Pi clone with Gigabit Ethernet, 2x RAM, stronger GPU
The latest single-board computer from FriendlyElec features a quad-core ARM Cortex-A53 processor.

• The NanoPi K1 Plus from FriendlyElec is a Raspberry Pi clone that has double the RAM of the Raspberry Pi 3 Model B+.
• For storage on the NanoPi K1 Plus, users can leverage a microSD card reader and an optional eMMC module.

The new NanoPi K1 Plus single-board computer from FriendlyElec offers similar features to the Raspberry Pi 3 Model B+ with double the RAM for the same price—$35.

The NanoPi K1 Plus mirrors the access of the Raspberry Pi 3 B+ with a 40-pin header, and also uses the ARM architecture, according to the website. The NanoPi uses a 1.3 GHz Allwinner H5 ARM processor with ARM Mali-450 hexa-core graphics, as opposed to the 1.4 GHz Broadcom BCM2837 SoC used by the Raspberry Pi.

The big difference is in the memory. The NanoPi K1 Plus claims 2GB DDR3 of RAM, which is double the 1GB LPDDR2 SDRAM of the Raspberry Pi 3 B+.

SEE: IT hardware procurement policy (Tech Pro Research)

Storage on the NanoPi K1 Plus is handled through a microSD card reader (which supports external storage up to 128GB), and users have the option to add an eMMC module for additional storage.

One other difference between the two devices is in wireless connectivity. While the Raspberry Pi features 802.11.b/g/n/ac wireless, the NanoPi K1 Plus only has 802.11.b/g/n with a PCB Antenna, the website said. So, for users who absolutely need AC wireless, it may not be a good fit.

Additionally, the NanoPi has an onboard microphone and infrared receiver. These features could make it a good fit for an embedded computing solution, such as a smart kiosk or digital sign in an office.

Other features include Gigabit Ethernet support, three USB 2.0 ports, a 3.5mm audio jack, a DVP camera, and HDMI. The NanoPi has the same dimensions as the Raspberry Pi 3 and, in theory, should be able to fit in any of its available enclosures.

Full Windows 10 Desktop on Raspberry Pi!!!
Windows 10 has been available for Arm based Always-on, Always-connected laptops for more than a year. It is a rebuild of the Windows source, not for x86, but for Arm, specifically for Qualcomm's Snapdragon 835, 850 and 855. Some clever people on the Internet have created the right bits of glue so that you can now install Windows 10 for Arm on the Raspberry Pi!

Dr. AMK, I love your enthusiasm!

But except for kids learning about computers (which these kits are great at), this is going majorly backward for most, if not all here.

1/2GB's RAM? 1.3/1.4GHz Arm processors? Win10?

I did that experiment years ago (not on ARM; Intel Core 2...) and was suitably impressed. But not enough to use the system for more than a few minutes and then wiping it again.

Great teaching potential. Great learning potential.

Usability? Yeah; that's my question. What would these be best used for?

The Raspberry Pi team has stuck with tradition by following its Pi 4 a year or so later with the Compute Module 4. Those expecting another DDR2 SODIMM sized board are, however, in for a shock.

 

Ubuntu 20.10 goes full Raspberry Pi, from desktop to micro clouds: Full fat desktop on a Pi is usable
But company also has its eye on Kubernetes at the edge
https://www.theregister.com/2020/10/23/ubuntu_2010_goes_full_raspberry/

Ubuntu 20.10 is out, with Canonical highlighting its Raspberry Pi support, including not only desktop support but also micro clouds based on MicroK8s, the company's lightweight Kubernetes distribution.

Codenamed "Groovy Gorilla," Ubuntu 20.10 is only supported for nine months, unlike its predecessor 20.04 which is a long-term support release. It is based on the 5.8 Linux kernel, which is a substantial upgrade from 5.4 as used in 20.10, with Btrfs RAID 1 support, USB 4 (based on Thunderbolt 3), updates to support features of recent CPUs Intel Ice Lake and Tiger Lake graphics, AMD Zen 3, and more. Also included by default is GNOME desktop 3.38, the latest version.

@Dr. AMK - have you ever tried using an RaspPi as a DSP? Or played with making it master to a slave analog DSP over I2S? Or how about Arduino code like the Teensy 4.1 from PJRC as a microcontroller using an ARM M7 chip? ( https://www.pjrc.com/store/teensy41.html )

 

Unfortunately, I didn't use it for any of that.

 

Cool. I'm just currently working on a project (building tower speakers) with an active crossover and building my own plate amp. The amplifier I got was from Sure Electronics (Wondom), the JAB5 ( https://store.sure-electronics.com/product/AA-JA33286 ), which has an Analog ADAU1701 ( https://www.analog.com/en/products/adau1701.html ) chip in it. I've already built a custom program using Analog's SigmaStudio software ( https://www.analog.com/en/design-center/evaluation-hardware-and-software/software/ss_sigst_02.html ).

But, I want to create a Finite Impulse Response filter for the signals, which my current design only allows for 550 coefficients. That's alright, but the arduino code powered Teensy 4.0 and 4.1 can run 20,000 coefficients. I'm also looking into RPi to see if the A series can run more coefficients for a FIR. Granted, only the more recent Cortex-M has the built in dedicated DSP hardware accelerator, but raw power at higher frequencies at times can still accomplish more than that.

So, I'm still digging because adding an ARM that can support a co-processor to connect the development board to the board with the dedicated DSP, and send the signal from the slave to the amplifier channels seems like how I'm headed. Which I have a 36V DC 500W PSU which will drive all of this, with 100W to 2 channels and 200W to 1 channel. Considering 80% mark, that puts it around 360W or less for driving the speakers I have (whose RMS is 80W, 100W, and 150W on the sub). Adding in powering an ARM board should be trivial, just some soldering.

Then comes making the ADAU1701 play nice as a slave to the ARM chip. But that will come after I fully explore which board will be the best to join with what I have.

Attached is the program I made in sigmastudio (don't know if this type stuff interests you or not, but if you want to take a look). I really like how intuitive the UI is for it.

 

You did a great work, I like the idea as well,
I know a good friend can help you, he is working at IBM, I'll share with him your post and see if he can give you some support.
Good luck.
Regards,

 

That would be awesome. Thank you!
