Technical Specifications

Pro Mini Board:

• Dimensions: 18mm x 33mm
• Weight: ~2 grams
• Input Voltage: 5-12V (RAW pin) or 5V (VCC pin)
• DC Current per I/O Pin: 40mA
• DC Current for 3.3V Pin: 50mA

USB Programmer:

• Interface: USB 2.0
• Output: TTL Serial (RX, TX, DTR, VCC, GND)
• Supports: 5V logic levels

Getting Started

1. Install Arduino IDE on your computer
2. Install CH340 drivers (if required for your operating system)
3. Connect the USB programmer to the Pro Mini's serial header
4. Connect USB programmer to your computer
5. Select "Arduino Pro or Pro Mini (5V, 16MHz)" from the Arduino IDE
6. Upload your sketch and start creating!

Perfect For

• Arduino beginners looking for a complete kit
• Makers transitioning from prototyping to permanent installations
• Students learning embedded programming
• Hobbyists building space-constrained projects
• Engineers developing production prototypes
• Anyone needing a compact, reliable Arduino solution

Why Choose This Kit?

Unlike the Arduino Uno, the Pro Mini lacks a built-in USB interface, making it much smaller and cheaper for permanent installations. This kit includes the necessary USB programmer, giving you the best of both worlds: easy programming during development and a tiny footprint for your final project.

Programming Notes

• Use the standard Arduino IDE (version 1.6.0 or later recommended)
• Select the correct board and processor from the Tools menu
• Connect the programmer pins correctly: GND-GND, VCC-VCC, TX-RX, RX-TX, DTR-DTR
• The auto-reset feature eliminates the need to manually reset during uploads
