Features

  • Arduino Pro Mini
  • Detachable Human Interface design (HID)
  • Flexible Input power
  • I/O Boards
  • Mounts in a standard extruded Aluminum enclosure

Arduino Pro Mini

  • Inexpensive and widely available
  • I/O
    • 14 digital input/output pins (of which 6 can be used as PWM outputs)
    • 6 analog inputs
  • On-board resonator
  • 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

Detachable Human Interface design (HID)

Input power

  • Wide input voltage range
    • 5-23V (for 3.3V Arduino Pro Mini)
    • 7-23V (for 5V Arduino Pro Mini)
  • 2.1mm DC Power Connector Jack
  • RF filter into Switching regulator board
  • 2nd RF filter into HID card
  • Mini360 Switching Mode Power Supply
    • About $1
  • Jumper to use raw input and not populate the Mini360
    • Uses the inputs jack as RAW power into the Arduino Pro Mini
    • 3.35-12 V (3.3V model) or 5-12 V (5V model)

I/O Boards

  • Arduino pins brought to 2x13 header
    • I/O pins are on 0.1" grid for easier prototyping
    • P2-P13, A0-A3
    • A4/A5 or SDA/SCL
  • Easily designed
  • 3 BNC or SMA connectors
    • Brought to headers
    • DB25 pass-through

DB-25 Example

  • Standard DB-25 female
    • Misses 1 pin of the 2x13 header in the box
    • OK, extra powers/grounds at the ends
  • Similar to (but narrower and female)
