Arduino Pro Mini 5V/16MHz Compatible Board — ATmega328P

Arduino Pro Mini 5V/16MHz Compatible Board — ATmega328P

The Arduino Pro Mini 5V/16MHz is the smallest and most minimal Arduino-compatible board — built around the ATmega328P with no USB chip, keeping the footprint tiny and cost low. Program via an external USB-to-serial adapter (FTDI or CH340). With 14 digital I/O pins and 8 analog inputs, it is ideal for space-constrained embedded projects, wearables, and permanent installations where a USB port is not needed.

Key Specifications

• MCU: ATmega328P | Clock: 16MHz | Voltage: 5V
• Flash: 32KB | SRAM: 2KB | EEPROM: 1KB
• Digital I/O: 14 pins | PWM: 6 channels | Analog in: 8 channels
• Interfaces: UART / SPI / I2C | Programming: FTDI / CH340 USB-serial adapter
• IDE: Arduino IDE compatible | Compliance: RoHS compliant

Why Choose This?

• ✅ Smallest Arduino form factor — ideal for wearables and space-constrained installations
• ✅ No USB chip — lower cost and smaller size for permanent embedded deployments
• ✅ 8 analog inputs — 2 more than Arduino Uno for multi-sensor projects
• ✅ Arduino IDE compatible — use all existing Arduino Uno libraries and sketches

Typical Applications

• Permanent embedded sensor nodes
• Wearable electronics and compact IoT devices
• RC model and drone embedded controllers
• Low-cost production Arduino projects
