These two commonly-available (Aliexpress) VL53L0X ToF distance sensor modules have different pin-outs, so I created a small #QWIIC (#STEMMA QT) socket to header socket adapter PCB that supports either one by populating the header in one of two positions. 🧐 😁

Some new parts arrived, probably hard to see in the picture, but I got a 5v to 3v level shifter for the #sparkfun #qwiic connector, a few qwiic connector cables (various types, but mostly qwiic to grove. or qwiic to dupont). This was all so the person sensor and the #M5Stack stuff could place nice together. I also picked up a M5Stack Univ V M12 #camera w/fish eye lens, a couple #Lilygo T-OI Plus boards (#ESP32 C3), a Lillygo T-Display S3 board.

This new "Dynamic NFC Tag" board from #SparkFun looks pretty neat. Acts like a programmable NDEF NFC for use w/ iPhone & Android and has chainable Qwiic / StemmaQT I2C connectors https://www.sparkfun.com/products/21274
