Features

  • Arduino Pro Mini
  • Detachable Human Interface design (HID)
  • Flexible Input power
    • On-board DC/DC buck regulator allows 7-23V input
    • Direct 7-9V input (USE VRAW jumper)
    • 3.3V or 5V Arduino support
    • Measured 12 mA with 9V input and 3.3V Arduino Pro Mini
  • I/O Boards
    • DB-25
  • Mounts in a standard extruded Aluminum enclosure

Arduino Pro Mini

  • Inexpensive and widely available
  • Arduino Pro Mini Schematic
  • I/O - 14 digital input/output pins (of which 6 can be used as PWM outputs)
    • Serial: 0 (RX) and 1 (TX).
      • Used to receive (RX) and transmit (TX) TTL serial data.
      • These pins are connected to the TX-0 and RX-1 pins of the six pin header.
    • External Interrupts: 2 and 3.
      • These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value.
      • See the attachInterrupt function for details.
    • PWM: 3, 5, 6, 9, 10, and 11.
      • Provide 8-bit PWM output with the analogWrite function.
    • SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK).
      • These pins support SPI communication, which, although provided by the underlying hardware.
    • LED: 13.
      • There is a built-in LED connected to digital pin 13.
      • When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.
    • 6 analog inputs
  • On-board resonator (8 or 16 MHz)
  • Reset button
  • A six pin header can be connected to an FTDI cable provide USB power and communication to the board
  • 3.3 or 5V
  • 8 MHz (3.3V) or 16 MHz (5V)
  • Programmable in Arduino IDE
