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)

Worked as expected, good assortment
Size: 30 PCS
Used these to replace missing/broken body panel fasteners and they fit as expected. The assortment covered what I needed without having to buy multiple packs.
Good quality for the price and handy to keep around if you work on vehicles.

Must have
Size: 200 PCS
If you have machines, you have to have these available. The old ones are reusable, most of the time, but when they aren't, you have these. They are of the same material and quality as OEM. Same size, of course, and the few I have used look factory.

Replacement for those infamous fastener rivet clips.
Size: 200 PCS
Any one who rides or owns a ATV or UTV knows exactly how temperamental this clips can be, they work great when new but as soon as you take them out they never fit right again. This is why I purchased this kit and the clips are exactly the same as Polaris OEM clips. These clips fit into a 8.5mm or 0.3” hole, I’m not sure what other ATV/UTV these will work on but verify your hole size before purchasing. Kit includes 150 fastener rivet clips and 1 remover tool which is made of decent quality and will get the job done until you can purchaser a better removal tool.
