Arduino Pro Mini 5V 16MHz

Description

The Arduino Pro Mini is a compact, breadboard-friendly board built around the ATmega328, running at 5V and 16MHz. It has an onboard voltage regulator (accepts 5-12V on the RAW pin) but no onboard USB – programming is done through an external FTDI/USB-to-serial adapter connected to the 6-pin header, making it a good fit for permanent, space-constrained builds where you don’t need a USB port after upload.

Features

• ATmega328 microcontroller, 5V logic, 16MHz clock
• 32KB flash (0.5KB used by bootloader), 2KB SRAM, 1KB EEPROM
• 14 digital I/O pins (6 PWM-capable: D3, D5, D6, D9, D10, D11), 8 analog inputs (A0-A7)
• No onboard USB – programs via external FTDI/USB-serial adapter through the 6-pin header
• Compact form factor, ideal for space-constrained and embedded projects
