    Arduino Matrix Keyboard Push Buttons AVR ARM Arduino Plug-in Kits Arduino LED
    Dec 14, 2017
    Not a significantly handy tool
    The product is well built, compact, and basically a good idea but somewhat hard to incorporate in a circuit. You have to design your pin assignments to work with the way this plugs in. The LEDs are all tied to a common pin, which would usually be ground (or +), but if you need one isolated there is no way to do it. The buttons are very small and somewhat hard to access, but work OK. I wouldn't recommend putting them directly on the connector header on the Arduino because there is no good way to press the buttons without supporting the free end of the board. Using this board on a breadboard is an option. I prefer to run wires to a switch on a breadboard.
    MCSAITE 8017 78-Key Portable Mute Ultra-thin USB Wired Computer Keyboard W5A1

    Great little portable size keyboard if you don't need a separate number pad.
    Pros Nice small compact size. Handy for portability. Especially if you don't need a separate number key pad. Number pad keys are activated with the Fn key plus letters. Cons Just a tad under normal size key bed makes it easy to make mistakes. Note - there is no SHIFT key on the right hand side.
    US 50000mah Power Bank LCD 2 LED 3 USB External Battery Charger For Smart Phone

    50,000 maH battery bank
    Nice looking, well-built, easy to use, Digital readout is nice. However - 50,000 maH is total bogus. You will not find a reliable 50,000 maH unit for anywhere near that price. The physical weight alone is strong evidence that this is closer to 5000 maH. These are just plain overrated. As a 5,000 unit, it's about what you'd expect. I don't yet have enough evidence to rate it's performance life - like how many times it will charge and recharge.
