Shipping Soon & New Project Ideas!

by Thierry GUENNOU

Dear Backer,

Crowdfunding orders are shipping soon, and I’m already thinking about the next project.

Preparing for Shipment

I am glad to announce that all boards ordered by the "644/1284 Narrow" project backers have been shipped to Crowd Supply and are being prepared for delivery to backers. I hope you will like this product. I have already heard some feedback of, "what a relief when I saw ‘Sketch uses 1204 bytes (0%) of program storage space’!"

The user’s manual is available at https://github.com/mrguen/644-1284-Narrow/tree/master/doc.

Let me know if you encounter a problem or would consider some modifications of the board.

Please take this time to check your delivery address, and update it through your Crowd Supply account if needed. Updating your shipping address helps avoid delays and get your orders shipped successfully. Once your order details have been sent out by our warehouse team for processing, it can be hard or impossible to re-route a shipment. Please contact Crowd Supply Support with any shipping questions or concerns.

If you would like to buy a bulk of boards at a gross price, contact me directly. We would need to arrange a new production batch by adding a couple of pre-orders (at least 50 boards of one model). For single or small orders Crowd Supply has some stock that will be available soon.

New Project Ideas

Also, I plan to launch another project on Crowd Supply next spring. There are a couple of possibilities that I’m working on. For example, two of them are:

  • A 3 channels clock generator. From 2.5 KHz to 200 MHz based on Si5351.

You can check out the Sketchfab design here: https://skfb.ly/6AwxH

  • Two models of spectrum analyzers using an FFT computation with at least 4096 samples. Model 1: bandwidth 1 Hz - 480 KHz, sensitivity 74 dB. Model 2: bandwidth 1 Hz - 25 KHz, sensitivity 140 dB.

You can check out the Sketchfab design here: https://skfb.ly/6VJKD

Any of these projects, (which share a common user interface made of a TFT screen a user button and a selector), are programmable in the Arduino environment and expose some communication ports. Most of them would cost around $40.

I’d love to hear your thoughts on what the next project should be! If you have a preference or ideas, let me know what would be more interesting to you and maybe some design requirements…

Have a nice day. Stay safe.

I have been interested by electronics as a hobby for a couple of years and wanted to go as far as possible in the development of a finished product.
