Arduino Pro Mini 5V 16MHz A-STAR Version

From the shop's description

Description: The Pro Mini 5V/16MHz is basically an Uno or Nano which has been stripped down to its most basic configuration for the smallest size, lowest power and lowest cost. It is primarily designed for permanently embedding into a project. Package Includes: Pro Mini 5V/16MHz 1×12 male headers (x2) 1×6 right-angle male header Key Features of PRO MINI 5V/16MHZ: ATmega328 processor running at 16MHz 32KB Flash memory 14 Digital I/O 6 PWM shared with the digital I/O 8 Analog inputs of which 6 can also be used as digital I/O for a total of up to 20 digital I/O 1 I2C and SPI port 1 Hardware serial port 5V Operation Arduino compatibility The A-Star Arduino Pro Mini ships with a preloaded Arduino-compatible TTL serial bootloader (which uses 0.5 KB of flash memory, leaving 31.5 KB available for the user program). We provide a software add-on that enables the board to be easily programmed from the Arduino environment. Since the A-Star’s ATmega328PB microcontroller is backward-compatible with the ATmega328P commonly used on Arduino boards (like the Arduino Uno and Pro Mini), existing programs and libraries written for a standard Arduino can be used on the A-Star 328PB without any changes (except to account for clock speed differences when necessary). However, our add-on includes support for the new features on the ATmega328PB, making them easier to use from the Arduino environment and allowing the A-Star 328PB to be an upgrade from ATmega328P-based boards.
