Arduino Pro Mini 3.3V 8mhz (Official)

ATmega328P Core Running at 3.3V / 8MHz: Powered by the ATmega328P microcontroller tuned specifically for low-power 3.3V operation at 8MHz clock frequency.

Ultra-Compact Minimalist Form Factor: Miniature breadboard-friendly PCB footprint designed without bulky onboard USB hardware to minimize power draw and physical space.

14 Digital I/O & 6 Analog Inputs: Provides 14 digital input/output pins (6 supporting PWM) and 6 analog inputs for interfacing with low-voltage sensors and components.

Native 3.3V Logic Level Compatibility: Operates directly at 3.3V logic levels, eliminating the need for logic level shifters when connecting 3V sensors and wireless modules.

FTDI Header for Programming: Includes a standard 6-pin FTDI programming header for quick connection to external USB-to-UART serial adapters.

PCB & Pin Construction: Built on a durable multi-layer FR-4 glass epoxy printed circuit board with clear silk-screened pin markings.

Power & Voltage Precautions: Strictly operate at 3.3V DC logic. Never apply 5V directly to I/O pins or the 3.3V rail to prevent permanent damage to the microcontroller.

Handling & ESD Protection: Practice standard anti-static procedures when handling exposed circuit pins; power off connected external hardware prior to adjusting pin connections.

Environmental Limits: Operating temperature range is -10°C to +60°C. Keep protected from static discharge, conductive metal debris, and moisture exposure.

Ideal for Low-Power & Battery Projects: Market to makers building battery-operated IoT nodes, wearable tech, and remote sensors where low power consumption is critical.

Direct 3.3V Sensor Pairing: Highlight how the 3.3V logic native design saves setup complexity and space by connecting straight to modern 3.3V sensors, OLEDs, and RF modules.

Recommended Cross-Sell Add-ons: Pair with FTDI USB-to-Serial TTL Adapters, LiPo Battery Chargers, and 3.3V Sensor Modules.

Clean Space-Saving Pitch: Position as the go-to board for compact, permanent project installations where a full-sized board or onboard USB chip is unnecessary.
