Round display EYESPI tester is a go! 👁️🔍

This 1.3" round TFT display will be in the shop soon, thanks to this tester, which lets us quickly verify all functionality: We're reading a display bitmap off of the SD card, displaying it, and then pulsing the backlight. We do this all through the EYESPI connector https://www.adafruit.com/search?q=eyespi and this one is passing just fine. After we package the display, we can stock it in the shop!

Wooo, this one is for all of our fans of fans.

We got some 5V USB-cable fan samples, and we're testing them out. These are handy when you need air cooling or to add motion to lightweight robotics. They come in various sizes, from petite 4cm to bountiful 9cm, and have two mesh screens to keep wires and fingers from getting caught in the blades.

Got lots and lots of solenoids?

We were chatting with a customer and realized we need a better solution for customers with many solenoids or other high-current on/off loads. This breakout will make it easy to control and power many inductive or high-current loads. An mcp23017

with a 1N4007 flyback diode.

Terminal blocks allow for quick wiring to power and each high current output, including one chunky block for the power input. The other 8 expander I/Os are exposed if you want buttons or simple LEDs. The breakouts have stemma QT for fast chaining/control over I2C.

Bus Pirate 5 is in stock and shipping now, going fast! 🚌 🏴‍☠️

Bus Pirate 5 is the latest edition of the original universal serial interface trusted by hackers since 2008. We've stocked and loved the Bus Pirate 4 for years and are excited to see the latest and greatest from the minds at WhereLabs.

The Bus Pirate is a RP2040 based, open-source hardware debugging tool that converts simple commands into common bus protocols such as 1-Wire, I2C, SPI, UART, several LEDs and more. Send commands to a chip or sensor and get the response, without writing a line of code.

TMC2209 stepper motor driver board testing 🤖⚙️🔋

We've been testing the Trinamic/Maxim/Analog/WeylandYutani TMC2209 (https://www.digikey.com/short/8r5m38h8) breakout we designed, and it's working great - the step/dir interface plus the micro-step select allows a microcontroller to control a stepper with just GPIO and true-to-its-name it is a very silent stepper driver, much quieter than the A4988 (https://www.digikey.com/short/tfjt88dd)! There are a few different I/O pins on the TMC: Index tells you when a full step is completed, which is handy to know when you want to change stepper modes on the fly. Diag lets you know when a power or motor failure has occurred. It can also tell when the motor has stalled if it's configured to. Finally, and most interestingly, is the UART interface: this unidirectional pin lets you read and write configuration registers, set 1-128 microsteps, change current limiting, and detect stalls for 'auto homing'. So far, everything works; we're just going to swap the direction of the potentiometer so it twists clockwise to increase the current limit and book PCBs!

LPS28 - from EYE ON NPI to new product in the fruit shop 🚀🌡️📦

We covered the TI LPS28 on EYE ON NPI a few years ago,

and we even designed a little breakout for this nice absolute temperature/pressure sensor. But chip prices were still a little nutty, and we didn't want to pay 2x or 3x for the chip. Now prices are reasonable again,

https://www.digikey.com/short/bfd48tt5

and we will send out prototype PCBs to get them into the shop. Coming soon.
