3PM ET TODAY! Desk of Ladyada - RaaAWWwwwr PLEO battery repair 🦖🤖🔋
Part 2 of Desk of Ladyada! Last week, we tackled a battery issue with our old PLEO dinosaur robot by sourcing high-capacity NiMH packs from DigiKey. And, we'll look at the need for a specific 12V US AC/DC adapter with an 800mA output and a 3.5mm OD plug to replace the UK plug, ensuring the robot could be charged again!

3.5mm headphone port (Line out blue). It's like a dead bug :( Who killed him? What did he deserve to get this fate? 3 conductor, 5 lead. Kinked pins.
Excellent article about Digikey - A small U.S. town grew a big company. Can it weather the tariff blizzard?
A rural Minnesota town is home to the biggest tech giant you've never heard of. Now it's riding out an unprecedented kind of storm.

PCM510x MCLK-less I2S DAC with line level out 🎧💻
We're starting to stock a lot of chips that are able to do digital I2S out, which makes for great-quality audio playback. That's great when you have enough processing power to decode WAVs or MP3s in real-time. However, we could really use some better DACs in the shop. We like the UDA1334A
This fully-featured UDA1334A I2S Stereo DAC breakout is a perfect match for any I2S-output audio interface. It's affordable but sounds g
..., but that's technically discontinued - it's great because it doesn't require an MCLK that some boards like the Raspberry Pi don't have and doesn't need I2C configuration either. The PCM510x is a good family, too; it ranges from the inexpensive PCM5100 (https://www.digikey.com/short/z50cnp0h) to the PCM5102 (https://www.digikey.com/short/80z2nh3h) which has high quality output at a higher cost. This breakout could use any of the family chips & gives you all the GPIO needed with a 3.5mm headphone jack for line-level output.
Desk of Ladyada - Tariff Talk! ASK AWAY! 📦🌎💸
We're doing the show tonight or Tues, so much is going on. Lots more questions came in too! Post yours before we go live…
This week was not a big week for engineering because we're neck-deep in tariff management! We had a video on Wednesday about the first round of tariffs announced—they have since been ratcheted up to 20% + 125% = 145% minimum on products from China and Hong Kong. "Retaliatory" tariffs on products from other countries have been paused, but there's still a 10% global tariff.
Then on Friday, it looks like some HTS codes

were "exempted" temporarily
Securing America's Borders
Let's take a look at the CBP (link) and the exempt tariff codes
and see how they might apply to the kinds of stuff we use to do our electronics engineering.
The Great Search - How to Source Tariffed & Non-Tariffed Items on DigiKey
https://www.digikey.com/short/2nb7nzb3
Since this is the topic of the day, we'll be looking at how to purchase an item from DigiKey with tariffs in mind. DigiKey is a free trade zone, which means that if you're not in the USA, you will not have to pay additional tariffs on goods that are re-exported. However, for USA destinations, the new tariffs can add a significant cost if the component has its last manufacturing step in China.
Let's use the example of a simple I2C-controlled temperature sensor to see how our sourcing decisions may be impacted by tariffs.

QT adapter for Sensirion SEN6x 🔌🌡️
Sensirion just came out with the new SEN6x series of 'everything including the kitchen sink' environmental sensors - and you can pick them up at DigiKey right now
https://www.digikey.com/short/c4tndnd4
We noted that the cable for the 6 series is the same as the SEN5x, BUT power supply requirements differ, so our existing SEN5x adapter won't work
Now you can quickly integrate the Sensirion SEN54 / SEN55 environmental sensor node into your microcontroller or microcomputer pro
Here's a simple level-shifting breakout that converts to the JST GH cable connector
This cable is a little over 100mm / 4" long and fitted with JST-GH compatible 6-pin connectors on either end. We dig the soli
