AURSINC Radioberry Juice USB Board, for CL016 and CL25 FPGA Based Radioberry Card, SDR Transceiver

I purchased the amp board before I noticed that it was not supposed to be compatible with the Pi4 board and required the Juice interface. I am glad I didn't see that in the description because I have it working perfectly with a Pi4, without any issues or modifications. The Pi4, Radioberry, and amplification board drive my Micro PA-50+ at 52 watts on 40m. I attached a couple of photos. I am using a voltage regulator to provide 8.4 volts to the amp board. I could use some help with the PTT interface. Anything I plug in automatically keys the Radioberry and amp.

This thing works pretty well. If you're looking at it, you've probably read at least a bit about it already. It's an ad9866 and FPGA based 0.1-30mhz DDC/DUC transceiver with 100mW output. The software gets a bit tricky as the driver presently doesn't seem to work on 64 bit kernels. Recent changes in debian (and raspios) have made a 64bit kernel the device on rpi4. Make sure you install a 32 bit, NOT 64 bit version of raspios bookworm. Edit your boot/firmware/config.txt and add arm_64bit=0 and reboot before trying to build/install the driver.

The product arrived in a short order of time. The product was package to electronic standards. The information to make it work is very vague. The product pamphlet tells you to go to a few places on the web to figure out what Raspberry Pi OS you need and all the commands. The problem is I had setup a my friends board just a week ago and was able to get it running with a lot of retries and combinations. This took at least 18 hours of my time. Some of that is the web information and what's on YouTube tells of a different Pi OS and different processes to load the software. I could not get the driver to load on this Radioberry board. I am thinking something is wrong with the board. Better information is needed from the Seller of this Product and some help. I would like to return the product if I cannot get this board to work. So far after three days of trying to get support. No support has been provided. If the rating could be zero stars I would rate this product. So far after 4 back and forth messages to seller and 20 phone calls to Amazon the problem is still ongoing. They send out pictures of links and links that go to no information.

Excellent, delivery beyond expectations

It is my second order. Found lot of cold soldering. On the other hand some of the solder points are so big, example sma, that they connect to radioberry board when mounted. first order was "okay". At all: check before mounting and fix it or send it back. whatever.

A small fan is probably a good idea to keep it cool, even though it has heat sinks. Without additional cooling they get hot enough that it is not comfortable to the touch.

You should know that the build quality on these Chinese boards is not the best, as far as the hardware is concerned. But more importantly, from what I've been able to tell after struggling for a week to get this thing to work... you might be able to get it to work, and you might not. Please don't think that just because you have some experience with Raspberry Pi's you won't have any trouble. I couldn't get the Radioberry driver to build, and I followed every tip and set of instructions I could find. I tried virtually every OS, 64 bit and 32 bit, that would run on a Raspberry Pi, installed all updates, upgraded, downgraded, tried two different Radioberry boards, two different Pi 4's, multiple SD cards, and tried every piece of advice in every forum I could find... the driver would not build. And I'm not a novice - I'm no Linux whiz, but I know my way around pretty well, and I've used Pi's in dozens of projects. I'm a retired programmer and a lifelong electronics and ham radio enthusiast and this is easily the most frustrating project I've ever undertaken. Whatever esoteric piece of Linux voodoo I needed to get this thing to work is not worth my time to know, and I'm not spending another hour banging my head against the wall with this thing.

Update: The seller reached out to make things right, and appear interested in improving quality control. I appreciate the seller reaching out and correcting the issue.I have purchased 3 of these radioberry's from AURSINC, and only one of them worked sorta. It works for a few minutes then dies. Sent the first one back, then got the second that didn't work, so I tried reflowing the adc, which sorta worked. It will work for a few minutes then die, So I blew the warranty on that one. So I tried again, and guess what, still another bad one. I will not remove this review unless the company makes this right. These are too expensive to to have ZERO quality control!
