Arduino Pro Mini Clone ATMega328P 3.3V / 8MHz

This board is a clone of Arduino Pro Mini

Clone of Arduino Pro Mini based on ATmega328P, made entirely with SMD (surface mounted) parts.

Specification:

• Microcontroller: ATmega328p
• Logic: 3.3V
• Supply voltage: 3.3 - 12V
• no USB connector
• Clock speed: 8 MHz

Like every Mini, this one is dedicated to more advanced users, who have some experience with electronics and Arduino. You get a very small device, but there's no USB/Serial converter for programming, no connectors and different ATmega supply voltage.

Because the microcontroler works at lower voltage and clock spped, it's prefectly suitable for low-power applications or when Arduino has to cooperate with other modules working at 3.3V (this is common e.g. among Bluetooth and GPS modules). In such case you don't have to bother with TTL 5V/3.3V level conversion.

If you're not interested in lower voltage and frequency, but want a small board, then Arduino Pro Mini 5V/16 MHz would be better choice for you. You may also consider buying cheaper clone.
