If, however, you're going to be uploading lots of sketches to your Pro Mini, you'll probably want to solder some pins (male headers) to the holes.

The Arduino Pro Mini is intended for advanced users who require flexibility, low-cost, and small size. It comes with the minimum of components (no on-board USB or pin headers) to keep the cost down. It's a good choice for a board you want to leave embedded in a project. Please note that the boards operates at 3.3V (unlike most other Arduino boards, which use 5V); be careful when connecting external components.

It's a good choice for a board you want to leave embedded in a project. Please note that there are two versions of the board: one that operates at 5V (like most Arduino boards), and one that operates at 3.3V. Be sure to provide the correct power and use components whose operating voltage matches that of the board.

The board comes without built-in USB circuitry, so an off-board USB-to-TTL serial convertor must be used to upload sketches. This can be an FTDI TTL-232R-3V3 USB - TTL Level Serial Converter Cable, the SparkFun FTDI Basic Breakout Board, or any other USB to 3.3V TTL serial convertor.

Arduino Pro Mini

The Arduino Pro Mini is intended for advanced users who require flexibility, low-cost, and small size. It comes with the minimum of components (no on-board USB or pin header) to keep the cost down. It's a good choice for a board you want to leave embedded in a project. Please note that the boards operates at 3.3V (unlike most other Arduino boards, which use 5V); be careful when connecting external components.

Uploading Sketches

The board comes without built-in USB circuitry, so an off-board USB-to-TTL serial convertor must be used to upload sketches. This can be an FTDI TTL-232R-3V3 USB - TTL Level Serial Converter Cable, the SparkFun FTDI Basic Breakout Board, or any other USB to 3.3V TTL serial convertor.

If using the FTDI cable on Windows, you'll need to make one configuration change to enable the auto-reset. With the board connected, open the Device Manager (in Control Panels > System > Hardware), and find the USB Serial Port under Ports. Right-click and select properties, then go to Port Settings > Advanced and check Set RTS on Close under Miscellaneous Options.

In Arduino 0011, use the LilyPad Arduino entry in the Tools > Board menu to compile and upload sketches to the Arduino Pro (do not burn the bootloader to the Arduino Pro from Arduino 0011). Arduino 0012 will include specific support for the Arduino Pro Mini.

Connectors
