Solenoids go clicky-clacky 🔩🔊🤖

We're testing out an I2C-to-solenoid driver today. It uses an MCP23017 expander. We like this particular chip for this usage because it has push-pull outputs, making it ideal for driving our N-channel FETs and flyback diodes. The A port connects to the 8 drivers, while the B port remains available for other GPIO purposes. For this demo, whenever we 'touch' a pin on port B to ground, the corresponding solenoid triggers provide an easy way to check speed and power usage.

Testing PIO support for RP1 chips on Pi 5 Computers

Ladyada tasked Jepler with exploring the new libPIO for Raspberry Pi 5 computers: this gives us access to the RP1 chip so that we can run custom PIO state machines on the GPIO pins. A common use case is NeoPixels, because of the tight timing requirements of the WS281x LEDs. Here is our first light test that shows it is possible…

🎉New Pico 2 W just dropped - and CircuitPython is ready to go!🎉

We just got the OK to put the Pico 2 W in the shop. You can pick it up at

Raspberry Pi Pico 2W is Raspberry Pi Foundation's update to their popular RP2040-based wireless ico board, now built on RP2350: the

, and you might be wondering: hey, do you have CircuitPython built for it? The answer is YES! We have secretly added support, and v9.1.2 has a build ready. We'll be adding it to the

CircuitPython supported boards.

downloads page shortly, but if you've got one in hand before launch somehow, you can check out the builds in the Absolute Latest S3 Bucket

the pico 2w is a great upgrade with twice the speed, twice the SRAM and twice the flash memory, solving many frustrations folks had with the original Pico W.

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,
