WARNING Improper handling of lithium batteries can result in an explosion of the batteries and/or release of harmful substances. Worn-out or defective batteries can compromise the function of this product. Replace the RTC lithium battery before it is completely discharged. The lithium battery must be replaced only with an identical battery.
Introduction Iono MKR combines the ease of use of the Arduino platform with multiple input and output interfaces; the result is a rugged, safe, reliable and easy to connect module, suited for installation both in industrial and residential environments. Iono MKR ships without any Arduino board, so you can use your preferred Arduino MKR board, as far as it is fully compatible with the Arduino MKR pinout and fits the Iono MKR case.
Features The Iono MKR modules key features are: ✓ 12÷28Vdc power supply, with surge and reverse polarity protection, and 1.1A resettable fuse ✓ compatible with 3.3V operating voltage Arduino MKR boards. Currently the following boards are supported: Arduino MKR WiFi 1010, Arduino MKR1000 WiFi (with headers), Arduino MKR ZERO, Arduino MKR GSM 1400, Arduino MKR FOX 1200, Arduino MKR WAN 1300 ✓...
Device identification The device can be identified with the information provided in the rating and identification plate, permanently attached to the side of the case. EXAMPLE RATING AND IDENTIFICATION PLATE Power supply Iono MKR can be powered with DC voltage only: ✓...

input/output lines, or for 1-Wire or Wiegand support, you can move jumpers J4 (DI6) and J5 (DI5) to the BYP position. NOTICE Note that, with the jumpers in the BYP position, you should limit the voltage applied to DI5 or DI6 between +0V and +5V (TTL level). Exceeding this voltage range will result in damage to the Arduino board and Iono MKR.
DI5-DI6 JUMPERS POSITION Analog output Iono MKR features a 0÷10V output (AO1) which can be controlled by the DAC0 pin of the Arduino board; the 0÷3.3V range of the DAC0 pin is converted to a 0÷10V output voltage. This is a sink/source output (the current direction at this output can be both positive and negative).

Hardware Installation For the initial set-up, the plastic DIN rail case must be removed to access the circuit boards and internal connectors. The case also needs to be opened to connect a USB cable to the programming port of the Arduino board, and if the factory configuration of the internal jumpers for the RS-485 termination resistors or digital input configuration must be changed (see below).
Arduino MKR board installation To install your own Arduino MKR board in Iono MKR, or replace a pre-installed board, no tools are required. The Arduino MKR board top side pin headers (female) connect to the pin headers (male) of the top Iono MKR board. The Arduino MKR board is installed upside down, with the micro USB programming near the relay outputs terminal block.
Iono MKR software development Since Iono MKR is just a super-sized I/O shield for a standard Arduino MKR board, you don’t need any specific library to work on it. Our libraries and examples, available with source code on GitHub, will provide you with some handy utilities to speed up your development, including functionalities to monitor the inputs (filtering out possible noise) and control the outputs, HTTP APIs, Modbus support and much more.
Optional components Real Time Clock module Iono MKR can be shipped with an optional, factory-installed hardware real time clock with a dedicated long-life non-rechargeable back-up battery. The battery is only used to power the RTC chip when the main power is not available. Depending on operating conditions it should last up to two years if the Iono MKR board is not powered, more if the Iono MKR receives external power.
Replace the RTC lithium battery before it is completely discharged. Replace the battery every 5 years even if the battery is still working properly. The lithium battery must be replaced only with an identical CR1025 Lithium / Manganese Dioxide (Li/MnO2) battery. Do not throw lithium batteries into fire, do not solder on the cell body, do not recharge, do not open, do not short-circuit, do not reverse polarity, do not heat above 100°C and protect from direct sunlight, moisture and condensation.
