Cheers to Giles Read to helping us see inside things!
The item in question is a 128GB Toshiba micro SDXC card. The microfocus tube makes it easy to adjust magnification by varying the position of the object relative to the detector; to give you an idea of the finesse you’re seeing here, the six fine bond wires to the right of the ‘fan’ at the bottom are about 400µm from top to bottom on the left size (and somewhat larger on the right side).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
