Did you know the PTSolns Leonardo+ is the ultimate "middleman" microcontroller bridge for your hardware projects?

The Leonardo isn't just a microcontroller; it's a native USB device! Because it supports the USB HID (Human Interface Device) protocol, it can send keystrokes, mouse movements, and gamepad commands straight to your PC.

Want to cut the cord? Combine the Leonardo with our fully compatible PTSolns NRF-Shield to add NRF wireless communication to your system. The PTSolns Leonardo+ acts as the perfect hardware translator, taking radio frequency (RF) wireless signals from the shield and turning them into real-time PC inputs.

What wireless hardware would you connect to your PC using a PTSolns Leonardo+ and an NRF-Shield? Let us know in the comments! 👇
Check them out on www.ptsolns.com and stay tuned for exciting new products updates!😝

User Project Highlight

***
This week's DIY electronics project highlight showcases a custom light chasing LED display, a brilliant build we first spotted at the Calgary Maker Faire this past weekend (May 2-3)!

The maker engineered an impressive free form soldered LED structure, completely driven by a custom-built control circuit. To bring this hardware project to life, the components and wiring were expertly integrated using the PTSolns Proto-Half V2.2 prototyping board; the perfect compact PCB for building and testing custom microcontroller circuits!

Build your next embedded systems project with us. Find our prototyping boards and hardware in 180+ countries on DigiKey: PTSolns.com/DigiKey

Access datasheets, pinouts, and supporting documentation on our technical repository: docs.PTSolns.com

Inspired for tinkering!

That's a wrap! Two full days at the Calgary Maker Faire. Thank you to everyone who stopped by at our booth. We will be back bigger next year!

We are excited for Calgary Maker Faire this weekend! Come find our booth and say Hi 👋

May 2nd & 3rd, Acadia Rec Centre

In terms of range tests, we're always looking for more! For this post, we'll be conducting one of the longest range tests with the PTSolns LoRa SX1276 shield. A friend of our shop recently took our PTSolns LoRa SX1276 915MHz Shield out into the countryside to test just how far radio waves would travel. The results? Rock-solid connection at over 6.15 kilometers (3.82 miles).

In this blog, we’ll explore the hardware that’s being used, the science behind the transmission, and just how impressive a feat it is to achieve a 6km range. PTSolns

We just published a real world LoRa range test and the results are impressive.

In this latest Tinker Thoughts Blog, we take the PTSolns LoRa SX1276 915MHz Shield out of the lab and into the real world to see what it can actually do. The result? A rock solid connection at over 6.15 km with simple hardware and no complex setup.

LoRa is known for long range, low power communication, and this test shows just how powerful it can be even in practical conditions.

Inside the blog:

Real field test setup and conditions

Hardware used and configuration

Measured range and performance insights

Why this matters for IoT, remote sensing, and low power networks

If you are working with IoT, RF, or long range wireless, this is a must read.

That was a fun tutorial to make! Though difficult to record this up-close. Thanks for the mention DigiKey 😎

Reversing the Polarity on LiPo Battery JST Connectors

Our latest LoRa SX1276 916MHz Shield for Uno is now live also on Amazon.ca

This board is a great way to get started with LOng RAnge (LoRa) communication, including the LoRaWAN! This shield is ready-to-go, no assembly required.

We have done a real-life range test and the results may shock you... read our upcoming blog post on Tinker Thoughts about that!

Included on the shield is the AHT20 sensor module, as well as a QWIIC connector.

We have tutorials on how to get started as well as full documentation on our Documentation Repository docs.PTSolns.com

Happy Tinkering!
