Hey guys,

Check out my recent project, a completely open-source LTE CAT-M shield for Arduino Uno, Mega, and Leonardo!

View the project:
- On Hackaday.io
- On Instructables
- On Arduino Create
- You can also view the board on my website

I'm planning on launching a crowdfunding campaign for this project in the near future (hopefully sometime next month), so stay tuned for more details!

Thanks and be sure to share!

Hi guys!

I'm excited to announce that I will be launching the Indiegogo campaign for this LTE/NB-IoT shield on 1 February 2018! You can check out the pre-campaign page here and be sure to share it with your friends!

Early-bird orders will ship out immediately but I will have limited supplies on a first-come-first-served basis. The price for any version of the shield will be $99 (USD) in case you're interested!

Happy holidays and stay warm!

Best regards,


Quick update: I added voice and audio support so you can connect a microphone and speaker or headset and make calls from your Arduino!  :)


What's up guys!

Yesterday I chatted with Hologram.io developers Ben Strahan and Chris Gammell and I'm super excited to tell you that for my Indiegogo campaign launching on Feb 1s all units delivered after the campaign will include a free Hologram SIM card and a promo code for $40 of free Hologram store credit exclusively for the campaign! Oh, and the price of the kits will be $89 (USD) instead of the $99 I originally stated!

If you haven't already, check out Hologram's site and developer plan because they have some really cool deals. All my tutorials use their SIM card because it's global, has 1MB free data per month, and super easy to use with a full API documentation and support so I definitely recommend it!

As a quick update on my progress on producing the shields, I'm working with a contract manufacturer in the US to produce more boards for the Indiegogo campaign pre-orders. Unfortunately there won't be any early-bird units available at the start of the campaign because they're all sold out! That's good news and bad news for some of you waiting for one out there, but I'll attempt to console you by saying that I might even start production before the campaign ends if I see enough demand, so please share this with anyone you think might be interested!

As always, check out some tutorials I made and stay tuned for the latest updates! Anyway, it's been a great ride and let's make this campaign even more awesome to spread the love of LTE and IoT!




​What's up guys!

It's midnight here and I just launched the Indiegogo campaign for my shield. Check it out here and be sure to share the link on social media because every view counts for me! Contributions are also greatly appreciated and will help me continue my efforts. I plan on fulfilling all orders regardless of how much I raise and I have everything ready to go with a contract manufacturer in the US.

Anyway, thanks for your support and I hope this will positively benefit the community!

Thank you for these updates, it was super interesting to read! Great project!
One question - does it apply also to LTE-M or just to LTE?
