I saw this toot today and got nerd-sniped hard.

I am pretty excited about the RP2350. It addresses pretty much all my minor complaints about the RP2040 and improves on it in a number of ways. It manages to be much more powerful, yet keeps the clean and straightforward design that's so foreign to so many ARM MCUs these days.

A pair of 150MHz CM33Fs with 520KB SRAM and up to 16MB of QSPI SRAM and 16MB of XIP QSPI flash opens up a lot of possibilities, while avoiding the complexity of larger SoCs.

Cursed footprint of the day: This SMD LED can be mounted either flat on the board, or at a 90 degree angle looking to the side 😲

New revision of the low-noise power rail oscilloscope probe is in and ready to test! Will it work or did I goof it up?! Stay tuned to find out!

electronics puzzle:

you find a circuit with a modern CMOS hex inverter IC. it has an 0402 package 1uF decoupling capacitor connected between VCC and GND, placed close to the IC package.

all but one of the inverter inputs are driven by an MCU, with their outputs driving (arbitrary) devices that pull 50mA.

oddly, one of the inverter inputs is directly wired to GND, and its output is wired to another 0402 1uF capacitor.

can you guess why someone might do this? (in production, not for testing)

If you need to find something specific while travelling, https://overpass-turbo.eu is a really powerful tool!

You don't need to know the query language; instead, try the wizard! For example:
