keyestudio Leonardo is a microcontroller board based on the ATmega32u4 (datasheet). It is an easy-to-use open source hardware.

It has 20 digital input/output pins (of which 7 can be used as PWM outputs), 12 analog inputs, a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button.

It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. 

Note that ICSP (In-Circuit Serial Programming) header can not only program the firmware to Atmega32u4, but also be used as SPI communication interface.

The keyestudio Leonardo can be powered via the micro USB connection, or via an external power supply jack (DC 7-12V) or even with female headers Vin /GND (DC 7-12V).

The Leonardo differs from other Arduino boards using separate USB-Serial chip in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard.

Great case for iPad
Color: Black
I saw a similar Zugu case for my iPad and almost bought it, but it looked like my iPad might not fit, so I hunted and found this VIKESI case, which cost about 1/3 as much as the Zugu. It's close to perfect. My iPad fits perfectly, and the almost infinite number of angles that it permits, along with magnets to hold it in place make it ideal for working on a desk or in my lap. The only minor downside is that it's on the heavy side, probably because of the magnets. But unless you're travelling with it (I've switched to a small Fire tablet for travel), that won't be an issue. Highly recommended.

The magnet does not stick to the refrigerator as advertised.. UPDATE ( I love it and it does stick)
Color: Pink
Although it is a nice case, it seems sturdy and it is very beautiful, my main reason for purchasewas I loved the fact that it sticked to the refrigerator. I was very disappointed to see that it does not. It’s too heavy, and it immediately begins to slide. That is the reason why I could not give it more than three stars. It disappointed me enough to where I’m really considering returning the item. UPDATE: I found out how to make a stick to the refrigerator and I absolutely love it! I changed my review and my stars! I’m really happy.

Great Protection, Great Fit — One Small Flaw
Color: Forest Green
I really love this case. It protects the iPad well, fits perfectly, and is still easy to put on and take off. The pencil holder is especially nice — it keeps the Pencil secure without feeling loose or flimsy. My only complaint is that some USB‑A to USB‑C adapters don’t have enough clearance to plug in. The edge of the case blocks certain adapters from seating properly. It’s the only issue I’ve run into, but it’s worth mentioning if you rely on chunkier adapters. Aside from that, this is an excellent case and one I’m happy to use every day.
