Why Your USB Serial Data Looks Like Garbage (And How to Fix It)

When you’re wiring together fast embedded systems (like an ESP32 feeding data into a Teensy 4.1) it’s easy to assume USB will “just work.” After all, USB is fast. Way faster than UART, right?

That assumption is exactly what led to a subtle (and very common) bug: perfectly timed data turning into unreadable garbage.

We are inspired by the students and educators that participated in the first-ever Ag Tech Robotics Challenge at College of Eastern Idaho! Using the AgXRP, robotics, sensors, and automation, to work through real-world agriculture challenges prepares students for the evolving landscape in precision ag.

This event got some great coverage on local news outlets!

Ooh! What Does This Button Do?

When you need a dependable, easy-to-hit input for your control panel, these 16mm Mushroom Head Pushbuttons, available in both red and green, can provide just what you need. Designed for high visibility interfaces and industrial setups, the oversized metal actuators deliver a satisfying tactile response. Each operates as a momentary switch, meaning the circuit stays closed only as long as you keep the button pressed, making it perfect for temporary activation circuits, reset functions, or machine controls.

We've also dropped the price on some popular concave arcade buttons! Check it out!

Teensy often serves as the "brain" of complex projects because of its tiny footprint and massive processing power. Inevitably, these projects require enclosures, mounting solutions, robotics parts, or other parts that can be 3D printed.

Turns out Teensy users have created an extensive collection of printable designs around Teensy boards. Take a look at these designs on our blog!

Build Something Awesome: The WPI XRP Medal Challenge Is Here!

What else could the XRP robot become? That’s the question behind the WPI XRP Medal Challenge—and we would love to see how you answer it. Worcester Polytechnic Institute (WPI), in collaboration with SparkFun, DigiKey, Raspberry Pi, 3D Printing Nerd, and Experiential Robotics, is inviting builders of all kinds—educators, students, robotics teams and innovators—to push the limits of the Experiential Robotics Platform (XRP).
