Wow we did a lil cleanout of some ~2 year old prototypes and found a bunch that were either forgotten or could not be made and now that there's a *slight* loosening of the parts shortage, we're able to wrap these up and get them into the shop: the ENS160 CO2 sensor, QT hub, QT level shifter, DS4420 are among the many we wrapped this week and ordered PCBs. We also got a big pile of prototype PCBs that will turn into future boards, let's take a look at some! We might also get to some nice wire-snap samples that arrived this week.

The Great Search - Stereo Headphone Amplifier with I2C Control

This week we're wrapping up the DS4420 breakout we designed 2 years ago, cause we finally found some chips! But as we got this board up and working we thought it would be nice to have a *stereo* version of this board. Let's look for an in-stock, stereo analog, line-level/headphone audio amplifier with I2C audio volume control. We've seen a lot of nice improvements to the Digi-Key search boxes and we'll feature some new search features we used to help find this part!
