Blog 6 – Developing for the Red Pitaya STEMlab 125-14 PRO Gen 2

2026-10-31T13:21:31Z

In my roadtest application, I suggested that I could go as far as running rtl_433 directly on the RedPitaya, inside its Linux OS and talking directly to the FPGA like the original apps are doing. For this, one would need to compile both the FPGA part...(read more)

Blog 5 – Software defined radio with the Red Pitaya STEMlab 125-14 PRO Gen 2

2026-10-30T17:00:52Z

Before applying for this roadtest, I read the documentation, in particular the sections related to SDR as it’s one of my pet peeves. What I found is that the SDR applications are imported from a dedicated developer named Pavel Demin who is offe...(read more)

Blog 4 – Logic analyzer application in the Red Pitaya STEMlab 125-14 PRO Gen 2

2026-10-29T15:33:08Z

In my application for this roadtest, I mentioned using the RedPitaya Logic Analyzer app on a blind remote that I have here: the MCU talks to a ATMEL 25010 EEPROM and a CC1070 transmitter chip, all on a 2.7V logic which is within range of the RedPitay...(read more)

Blog 3 – Oscilloscope application in the Red Pitaya STEMlab 125-14 PRO Gen 2

2026-10-28T15:39:02Z

One of the easiest way to exercise the analog frontend of the Red Pitaya STEMlab 125-14 PRO Gen 2 is by feeding it a known signal and see how it is perceived. For this,t he oscilloscope app is the best candidate. After starting the app, I plugged the...(read more)

Blog 2 – First contact with the Red Pitaya STEMlab 125-14 PRO Gen 2

2026-10-27T14:59:12Z

When connecting via a web browser, we get presented with a list of applications that can be used. One thing that must be kept in mind is that each application uses the FPGA in its own way, so you can’t run applications in parallel by opening m...(read more)

Blog 1 – Unboxing the Red Pitaya STEMlab 125-14 PRO Gen 2 Starter Kit

2026-10-26T17:10:36Z

Welcome to the first blog in my series dedicated to roadtesting the Red Pitaya STEMlab 125-14 PRO Gen 2 Starter Kit, starting with an unboxing video: https://youtu.be/q0jrmfBaZVA The box contains the RedPitaya board, a SD card, SMA male-male cables a...(read more)

Raspberry Pi CM5 roadtest - Finally, the USRP is working

2026-10-20T10:00:25Z

In my previous article about SDR++ on the CM5, I ended with an unresolved issue: although UHD was correctly detected during the SDR++ build and the USRP source was included, I could not get my Ettus USRP B205mini-i to actually work with SDR++. I deci...(read more)

POST 9 Partnering SDR & GNU Radio ...Red Pitaya STEMlab 125-14 PRO Gen 2 Starter Kit

2026-10-15T01:16:44Z

This my final post before writing the review. I’ve struggled up to this point to deliver on the objectives in my application. Well I am happy to report I was successful with wrangling the SDR part of the Red Pitaya into what I promised, a radio...(read more)

2026-10-12T17:44:19Z

Hailo-8L Thermal Logging The Hailo-8L module that I have is an extended temperature version with an industrial operating temperature range (-40C to 85C). Part Number: HM21LB1C2LAEProduct Name: HAILO-8L AI ACC M.2 B+M KEY MODULE EXT TMP It has two tem...(read more)

POST 8 A case in point...Red Pitaya STEMlab 125-14 PRO Gen 2 Starter Kit

2026-10-11T20:12:56Z

Recall from an earlier post, that I had ordered and then reordered a case for the Red Pitaya. The first case ordered from a local supplier, wasn’t compatible with the RoadTest unit. It would have been nice if compatibility was mention...(read more)

Raspberry Pi CM5 roadtest - SDR++

2026-10-08T21:00:13Z

In my previous CM5 RoadTest articles I covered the initial setup of the Raspberry Pi Compute Module 5 and the installation and testing of the RTL-SDR. The next step was to try SDR++, one of the more versatile SDR applications available for Linux. A...(read more)

Raspberry Pi CM5 - Frigate NVR Hailo-8L Integration

2026-10-07T05:06:34Z

It's amazing that almost exactly 2 years ago, I had posted Using an RPi Camera Module 3 with the RPi5 AI Kit. At that time I was waiting for the Hailo-8L capability to be added to Frigate NVR application, so that I could replace the Coral U...(read more)

Raspberry Pi CM5 - Frigate NVR Initial Benchmarks

2026-09-29T04:07:09Z

I combined the thermal and power logging programs from the previous blog into a single program, cm5_power_temp_logger.py. I also examined the Frigate API to see what type of statistics were accessible through that interface. I think th...(read more)

POST 7 I'm really done this time… Red Pitaya STEMlab 125-14 PRO Gen 2 Starter Kit

2026-09-26T18:52:22Z

SPOILER ALERT: The Red Pitaya powers down if the USB-micro connection on the module is used. On of my troubleshooting attributes that can be either a blessing or a curse depending on the horse, is that I am persistent. In a previous post I used the t...(read more)

POST 6 I'm taking the win...Red Pitaya STEMlab 125-14 PRO Gen 2 Starter Kit

2026-09-24T21:36:29Z

Simple exercise use the oscilloscope to display the signal generator. I'm not spending a lot of time here. This was not part of my application pitch. Just getting the unit configured (i.e. OS and network) has had it challenges. I'm taking thi...(read more)
