Here's a quick breakout we designed for it: By default, it works just like a diode, with VIN and VOUT terminal blocks. But if you want to access more features, there's a 0.1" breakout. The IMON pin gives a voltage from 0-1.5V as current goes from 0-5A. Plus, it has options for overvoltage and undervoltage lockout and a power good output. ☀️🔋

, especially since it can be configured not to require an external MCLK.

We designed and prototyped an RP2350 Metro a few months ago, and it worked OK, but we were really short on pins, which meant a lot of annoying compromises - so we ended up only fabbing the RP2350 Feather to start. With that design flying off the shelves, It's time to revisit the Metro. We wanted to jam-pack this design, and with the extra GPIO on the B we have plenty of peripherals: the 22-pin HSTX for DVI output, Stemma QT port, NeoPixel, JST 3-SH SWD debug port, 16MB flash, an extra spot for PSRAM, MicroSD card with SPI or SDIO connections, and 5V buck converter that can give us 2 Amp easily, which we'll need since we also have a USB Host port pinout for connecting USB peripherals. We even managed to get a couple of niceties like switchable power for the USB host power, a USB boot button as user input, and an SD card detect GPIO.

with designing something for us - we just said, "Make the best thing ya can," and he delivered! Check this board out that plugs onto the compute module and provides many great accessories: USB connection for bootloading/USB gadget, USB 3.0 host type A for CM5, micro HDMI, micro SD card for data storage on 'Lite modules, camera connection, and mount, two DSI connectors, fan connect, Stemma QT / Qwiic connection, and RTC battery. There's one shutdown button for CM5 and two GPIO buttons plus one LED. Timon's gonna try to add an EYESPI connector for our next rendering so we can get some I2C/SPI/PWM outputs easily. What do you think? We wanted to keep it compact and not too pricey (aiming for <$30 cost. We'll see if we can get it there) but were able to craft fairly complex projects in a small space.

OK, our 10164227-1004A1RLF (https://www.digikey.com/short/3z8mb49f) Compute Module connectors came in, so we're ready to fab this prototype of our Compute Module 4 or 5 backpack. Timon updated it to have an EYESPI connector to bring out some GPIO's and make it easy to connect small displays. There's so much packed on here; we're worried about how we're going to make a test jig for so many connectors! We may need to use an IO multiplexer to address so many pins with a microcontroller - while using a CM5 to do the test sounds 'fun,' it would not be good to have such a delicate board used for testing hundreds or thousands of these in the fabrication department.

It's a new year! Time to take on moooore projects! Maybe we'll replace the FONA family with LTE modules this year. The First thing we need to do is get a good SIM card holder. We don't have a breakout for one already, so we're just going to whip this one up so we have it ready for when we need to prototype. We can put it in the shop, too.

This is a similar "Step & Dir" type driver, with a wide motor range of 4.75 – 28 Volts and separate 3~5V IO pin. It has a couple nifty upgrades, though: like a diagnostic error output, index out so you know if you dropped a microstep, OTP config memory, and a half-duplex UART pin that you can use to configure and read stats from the chip. We kept the direction/step LEDs and the current-limit-set potentiometer, changed a few pins around, and voila! What do you think?
