Desk of Ladyada - Samples Sunday & Replacement SPI FRAM

We got a whole mess of interesting mechanical samples - from fancy-pants breadboards to encoders and joysticks. We're also doing a lil bit of refactoring of hardware designs, since it was time to re-order 1.8" TFT breakout PCBs we decided to give up a glow-up to add an EYESPI port. Also we've started the tester for the ESP32 ItsyBitsy.

We think FRAM chips are the most underrated storage chips engineers can use - they're excellent for datalogging! They also solve the biggest frustration when people try to stream data to EEPROM, SD card or Flash memory: erase times for blocks can stretch to hundreds of milliseconds, and you often need to write a whole block at a time. SRAM is nice but will erase itself when power is lost. If you need to burst-write data to a reliable storage medium that is OK with having power cut - FRAM is great. We have a few FRAM breakouts (https://www.adafruit.com/?q=fram&sort=BestMatch) but we've found some chips are discontinued/obsolete (https://www.digikey.com/short/wc94tmd2) - lets see what options we have for replacements - a good lesson in how to read and understand PCNs
