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.

This sexy little beauty is the Wemos Lolin ESP32. It has an onboard 128x64 pixel OLED screen which is easily controlled by the powerful ESP32 microcontroller. The small form factor, cheap price and powerful brains make it a perfect start for any IoT project. After I tried one I quickly ordered a few more to make sure I’ll always have a few of them in stock.

If you want to try one, check out AliExpress or EBay.

First of the Bones Rises – RP2350 Adalogger 🦴

With the RP2350 chip in wide distribution , we're now able to come up with a lot of variants of our popular RP2040 "Bones"

https://blog.adafruit.com/2023/01/22/rp2040-feather-bones-for-a-few-different-varieties/

that ended up becoming a dozen different boards.

We're starting with the 'Adalogger' design folks love: with a microSD card socket that is wired for SPI or SDIO. A separate regulator allows the I2C/uSD to be powered off completely for ultra-low power usage. This didn't make as much sense for the RP2040 because it was not a particularly low-power chip. There's also a Stemma QT port for plugging in external sensors.

What other "Bones" should we spin up?

Metro RP2350 is wrappin' up testing ✨🐢

This week we got our Metro RP2350 boards

the whole thing, it came up and pretty much works perfectly! Just one component needed a swap - we were able to test all GPIO, analog inputs, MicroSD slot, PSRAM, LEDs & NeoPixel, user button, I2C/SPI/UART, aaand power supplies. The 5V supply is great, we got a nice clean 5V out at 2A+ from 12V DC in. The last thing to check is the HSTX port, which gives us DVI access, and it works, thanks to this festive turtle demo!

BMI323 IMU breakout ⚙️🔍

We have a project we're working on with a BMI323 (https://www.digikey.com/en/product-highlight/b/bosch-sensortec/bmi323-inertial-measurement-unit) chip. Since this is our first time using the sensor, we decided to make a breakout for it! This chip has fast sample rates and an I2C/I3C/SPI interface. After we explore this chip, maybe we'll do an EYE ON NPI about it!

The SC16IS74x is an I2C to UART converter

If you know us, you know we luuuuuv I2C as a near-universal interface for sensors, GPIO expanders, OLEDs, and other various devices under our Stemma QT family: https://www.adafruit.com/search?q=stemma+qt 🌱. But we still bump into some UART devices: https://www.adafruit.com/search?q=uart here and there—GNSS/GPS units, MP3 playback chips, fingerprint sensors, LIDARs, and more.

These can be annoying if you only have one UART port-or none at all! So we put together this SC16IS74x breakout. It can use either the SC16IS740: https://www.digikey.com/en/products/detail/nxp-usa-inc/SC16IS740IPW-128/1301043 or SC16IS741: https://www.digikey.com/en/products/detail/nxp-usa-inc/SC16IS741AIPWJ/4486521 chips-both essentially the same for our purpose: providing a bidirectional UART with flow control. Address jumpers on the back allow you to select up to four devices on one I2C bus—and there's even native Linux kernel drivers: https://www.kernel.org/doc/Documentation/devicetree/bindings/serial/nxp%2Csc16is7xx.txt 🧠.
