Desk of Ladyada - A Tester-ful Week

SHT45 Trinkey tester launch, Feather ESP32 & Itsy Bitsy 32u4 updates, HV UPDI programmer fixes. Plus, designing a wide-band IR receiver for "code learning" projects.

This week we've been doing pre-taxes review and also working on a lot of testers. Specifically we've got the tester for the SHT45 Trinkey (https://blog.adafruit.com/2024/03/04/...) ready, plus we 'pico-ified' our Feather ESP32 v2 (https://www.adafruit.com/product/5400) from Raspberry Pi.

Ditto we also de-Teensyified the Itsy Bitsy 32u4. (https://www.adafruit.com/product/3677) - we wrapped our huge revision party in January but we are still working on tester-sweeps so you'll see more of those.

We also got more JST SH cables in so we can finally stock our HV UPDI programmer (https://www.adafruit.com/product/5893) board: this one had quite a few hiccups as we designed the tester totally wrong! In the end, we did get it working with a few analog trix.
