How looks like my second industrial Arduino?

Here it is!

Its main features are:
  • Industrial isolated power supply from 24Vdc to 5Vdc. It includes an idiot-proof diode to avoid connection damages;
  • Serial port with RS-232/485 connected to Arduino's Serial. This serial port includes a switch to enable activate Arduino's bootloader and download firmware;
  • Serial port with RS-485 and XBEE socket connected to Serial1;
  • One universal analog input with 0-5V, 0-10V and 0-20 mA. To choose the right setting, there are some jumpers (not mounted in this photo);
  • 4 isolated digital inputs;
  • 4 isolated high current digital outputs, with common darlington PNP transistors and reverse diodes for inductive loads;
  • 10 leds bar easily to check I/O;
  • LCD display (16 characters with 2 rows) to show anything;
  • 4 push-button for display;
  • RTC with supercap to keep time;
  • High capacity EEPROM to keep anything (small databases or datalogs);
  • M3 mounting holes and adapted to 107 mm DIN-rail mountings.
What's hidden below the LCD?

It is based on an ATMEL ATMEGA 1284P. It's a huge processor.

It's is not definitely, because I'm planning to remove the analog input and increase the digital I/O. There are also some issues to solve on the second serial port. So there shall be another release.

I'll call it picoLogic1284.
