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
MEMORANDUM FOR THE SECRETARY OF STATE THE SECRETARY OF THE TREASURY THE SECRETARY OF COMMERCE THE SECRETARY OF HOMELAND SECURITY THE UNITED
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.

Desk of Ladyada – RP2350 Bones Day https://youtu.be/sNEu8FY-e44
New RP2350 chips are here, and we're building fresh "Bones" boards—starting with the Adalogger RP2350. We also fixed Sparkle Motion's power issue and designed a Stick version. Plus, we're exploring tiny 1.1V regulators to optimize future boards.
Desk of Ladyada - Slow Sunday Pokes 🔧🎧📦 https://youtu.be/mrvS-7-kkfM
Testing a PCM5122 I2S DAC, adding LEDs to the 8x solenoid driver, and prototyping a "USB CC Fixer" to charge a tricky baby monitor. Also we're on the hunt for a stereo I2S amp with 5W+ output.
