Arduino Pro Mini 328 - 5V/16MHz
Overview
This board was developed for applications and installations where space is premium and projects are made as permanent setups. It is small, programmable, and powered by ATmega328P.
Features
Use:
- The Arduino Pro Mini can be programmed with the Arduino software download.
- Project Hub: this is a large collection of Arduino projects to try.
- Programming Forum: this platform is a place to find help for programming the Arduino Pro Mini generic.
- Power. This can be a regulated +5V power source (e.g. from the +5V pin of the Mini USB Adapter or an Arduino NG) connected to the +5V pin of the Arduino Mini. Or, a +9V power source (e.g. a 9-volt battery) connected to the +9V pin of the Arduino Mini.
- Ground. One of the ground pins on the Arduino Mini must be connected to the ground of the power source.
- TX/RX. These pins are used both for uploading new sketches to the board and communicating with a computer or other device.
- Reset. Whenever this pin is connected to the ground, the Arduino Mini resets. You can wire it to a pushbutton, or connect it to +5V to prevent the Arduino Mini from resetting (except when it loses power). If you leave the reset pin unconnected, the Arduino Mini will reset randomly.
- An LED. While not technically necessary, connecting an LED to the Arduino Mini makes it easier to check if it’s working. Pin 13 has a 1 KB resistor on it, so you can connect an LED to it directly between it and the ground. When using another pin, you will need an external resistor.
Specifications
- 14 digital input / output ports RX, TX, D2 ~ D13,
- 8 analog input ports A0 ~ A7
- 1 TTL level serial port transceiver port RX / TX
- 6 PWM ports: D3, D5, D6, D9, D10, D11
- Using Atmel Atmega328P-AU microcontroller
- Supports serial download
- Supports external 3.3V ~ 12V DC power supply
- Supports 9V battery powered
- Clock frequency 16MHz
- Size:33.3 * 18.0 (mm)

Best pillow ever!!!
Size: Sapphire Queen
I have actually tried dozens and dozens of pillows in my life, and dozens in the past three years, but this is it. Some cheap, some very very expensive, and some very famous brands. This one beats them all. So awesome and comfortable (side sleeper). I tried one and loved it so much I ordered a second right away. It is exactly what I've been searching for forever!!!
Stays in shape, extremely comfortable. Only thing is you definitely need a 32" pillowcase to cover it, and I wish they made a 34" pillowcase, but no luck. I used the pillow the same night and it's definitely worth the money.
No neck pain, super squishy but supportive, and no odor.

Great pillow
Size: Sapphire King, Size: Sapphire King
Super comfy pillow. Fluffs up without any issues and it was the first night in a long time I wasn't allover the bed trying to get comfortable. I appreciate the fact that the material in the pillow can be washed. The prefill was perfect for me so I did not need to remove or add but I like the option to do so. 10/10

Way fluffy, good support
Size: Sapphire Queen
This pillow is way fluffy. It does fit into a standard pillowcase with a little tugging and stuffing. Worth it though, as it’s cool and provides more support than a usual side sleeper pillow. I’m not using the extra stuffing that comes with it as the firmness is fine for me right out of the box.

Great for side sleeper
Size: Sapphire King
I am loving this pillow. I waited a few months to see how I would feel about it, because I definitely did not like solid foam pillows previously. I’m a side sleeper, and my pillows were discontinued from a different bedding company. I tried a few others in the interim and was not happy with the support for my neck. Tried this one and I really love the shredded foam. It supports my neck and my head, it’s comfortable. It is movable if I need support in a certain position. It has extra fill if needed. Super happy with this purchase.
