I'm guessing the Pico is a much simpler thing to make and in high quantities, so much easier to churn out to meet the demand
- moffkalast 4y agoYay, another useless 3.3 V microcontroller that needs a level shifter to do basically anything.
- guenthert 4y agomany i/o chips take 3.3V, especially for those with an I2C interface 3V3 ... 5V seems to be the norm. 5V only was 80s.
- rasz 4y agoYes, it wont interface directly with all the ECL circuits you keep in the basement.
- JKCalhoun 4y agoIf everyone went 3.3 V....

- throwntoday 4y agoDo you know of a chip that has 5V tolerance and ample GPIO? Needs to be ready to ship right now, and a $5 dev board would be nice.
- moffkalast 4y agoThe ESP32 has unofficial 5V tolerance on most pins so it can for example handle 5V serial with no problems (but can't output 5V of course), but my go-to is still the Arduino Nano for most things.
- yellowapple 4y agoI just used a Pico in a project a couple weeks ago and didn't need to do any level shifting at all. I'm kinda shit at circuit design, though, so maybe I did something wrong lol
- Filligree 4y agoMany circuits take "3.3 - 5V" inputs, so a 3.3V driver will usually work... unless literally anything goes wrong. They will usually work as far down as 3V, for that matter. These are analog systems, and there's a big difference between "works" and "works reliably, for months and years".
