“Exactly as described. Shipped as a PCB, with two screws. Easily attached to the Raspberry Pi Zero or Raspberry Pi Zero W, and has easy access to the MicroSD slot on the Pi Board.
Photos attached show the dongle attached to the board from underneath, on the side, from the top, and detached from the board, with a single AA and a single AAA battery for size comparisons.”
“Top quality accesory to allow your Pi Zero to be used as RNDIS/Ethernet Gadget under win with Acer Incorporated usb driver. Pi Zero without WiFi can share windows connection and get quickly on line. I am experimenting using a few Pi Zero with this accessory to mine crypto currency. So an easy way to create a miner station with many Pi Zero, virtually using no power, to mine crypto. The os to use is the Pi OS lite 32bit with no desktop enviroment as you can use the ssh to manage every single Pi Zero. A small 5v Fan is needed to cool down the Pi Zero/s. Youtube will help more on this dongle use of Pi Zero”
