A quick note to let you know that courtesy of David Mills, G7UVW, the Etherkit Si5351 Arduino library has now been ported to the Mbed platform. He reports that it seems to be behaving the same as the Arduino library, so if you’re an Mbed user, definitely go check it out. I was giving some… Read More Si5351 Library Mbed Port
I recently received this nice flowchart in email from Joe Marin, CO7RR which documents a method for programming the Si5351. It looks slightly different from the way I do it in the Si5351 Arduino library and I haven’t personally tried it, so I can’t vouch for its accuracy, but I wanted to pass it along in… Read More Si5351 Programming Flowchart
Arduino – Si5351 Powered Signal Generator Please enjoy this write-up of a nifty, compact signal generator project using the Etherkit Si5351A Breakout Board driven by a Teensy LC. What I really love about it is that it uses an 18650 LiPo cell with a small USB charge controller, so that it is very portable. Neat stuff!
I know that the updates here have been extremely sparse. For that I do apologize. Things are slowly starting to settle into a new normal around here, and I’ve been able to regain the ability to put time back into work. There’s a large to do list on my whiteboard, and many of the things… Read More Break My New Library
If you wouldn’t mind, I would like to draw your attention to my latest post on the Etherkit App Notes blog. In it, I detail how to create a 10 milliwatt WSPR beacon using nothing more than the Etherkit Si5351A Breakout Board, an Internet-connected PC, and a low-pass filter. A simple project, but one that… Read More 200,000 Miles Per Watt
I’m pleased to announce an upgrade to the Etherkit Si5351A Breakout Board with TCXO reference oscillator. In boards manufactured previous to today (and the ones kitted in the initial crowdfunded initiative), the TCXO used was a Fox FOX924B-25.000. It worked well and did the job it was supposed to, but has one flaw in certain situations. The… Read More Si5351A Breakout Board TCXO Upgrade
I know. I was just starting to get some momentum posting to the blog on a semi-regular basis, and then — the drop off. I am sorry about that. The Si5351A Breakout Board campaign consumed almost all of my work time. Given the limited amount of actual work time that I have, something had to give.… Read More Long Time, No See
I’m pleased to announce that I’ve opened up the Etherkit Si5351A Breakout Board campaign for contributions! Please stop by our Indiegogo page to get much more information on what we are offering, and how you can help to support us even if you don’t plan on purchasing a kit. We did a soft launch yesterday… Read More The Si5351A Breakout Board Campaign is Here!
Just a few days ago, I finally received some of the TCXO parts that I’ve been planning on using with the Si5351A Breakout Board. I had no problem using one on the remaining prototype circuit board that I have, and at first glance it appeared quite stable and also very close to the nominal frequency… Read More Si5351A with TCXO Update
In looking through the analytics here on the blog, I noticed a search term that has been regularly coming up near the top: Si5351 crosstalk. Realizing that I haven’t yet presented data on this, it seemed like a good time to knock this one out, since it isn’t that difficult of a measurement to make.… Read More Si5351A Investigations Part 8
