====== ULARI ECO Radio Interface Hardware ======

[[http://microsat.com.pl/product_info.php?products_id=180|ULARI ECO Radio Interface]] is based on NanoPi Neo 1.4 512 MB module from FriendlyARM. The device consists of a microprocessor module and an HAT board (HAT stands for “Hardware attached on top") with all necessary external components. The whole system includes:


  * Radio 6-pin minidin connector (Microsat standard, WX3in1-like pinout),
  * A 100 Mbit Ethernet connector,
  * USB connector,
  * RS-232 serial port (via 6-pin minidin connector),
  * DS18B20 thermometer connector,
  * Four SMD leds informing about device operation,
  * SD CARD connector for operating system image.


>This is not a standalone radio transceiver. You need a proper VHF or UHF amateur radio station to use the device for packet transmission and reception.

Radio 6-pin minidin socket is connected to microprocessor audio peripheral via a suitable analog frontend including necessary signal filtering, amplification and high frequency supression.

=== Rear panel RS-232 port pinout ===

RS-232 port can be used to connect any serial port devices with RS-232 voltage levels. Devices with low current consumption can also be powered from this connector. [[http://microsat.com.pl/product_info.php?cPath=29&products_id=171|GPS-RS232/Microsat/2]] is compatible and works nice.

{{:minidin.png?|Minidin 6 pinout}}

  * Pin 1 – 5V output, do not short-circuit, max. current 100mA,
  * Pin 2 – GND,
  * Pin 3 – hard-wired to negative voltage for WS-2300/WS-2350 weather station support,
  * Pin 4 – RS-232 Port 2 TXD,
  * Pin 5 – RS-232 Port 2 RXD,
  * Pin 6 – not used.

=== Front panel RADIO port pinout ===

RADIO port pinout is the same as in Microsat WX3in1 and PLXTracker/PLXDigi line of devices. Cables can be used interchangeably.

{{:minidin.png?|Minidin 6 pinout}}

  * Pin 1 - not connected,
  * Pin 2 - APRS audio output from the device to the microphone input of the radio. This output also acts as a PTT by shorting pin to ground through a 2k2 resistor - an option for portable radios that do not have a separate PTT input (selectable in configuration software, 2k2 resistor is built-in),
  * Pin 3 - not connected,
  * Pin 4 - APRS audio input from radio to WX3in1,
  * Pin 5 - Ground pin,
  * Pin 6 - PTT output - if the external PTT output is selected in device configuration, this pin is shorted to ground while broadcasting.
