1. The board
1.1 Application examples
The Arduino Edge Control is your gateway to Agriculture 4.0. Get real-time insight into the state of your
process and increase crop yield. Improve business efficiency through automation and predictive
farming. Tailor the Edge Control to your needs by using up two Arduino MKR Boards and an
assortment of compatible Shields. Maintain historical records, automate quality control, implement
crop planning and more through the Arduino IoT Cloud from anywhere in the world.
Automated Greenhouses: In order to minimise carbon emissions and increase economic yield, it is
important to ensure that the best environment is provided for the growth of crops in terms of
humidity, temperature and other factors. The Arduino Edge Control is an integrated platform that
enables remote monitoring and real-times optimization to this end. Including a Arduino MKR GPS
Shield (SKU:ASX00017) allows for optimum crop rotation planning and acquisition of geospatial data.
Hydroponics/Aquaponics: Since hydroponics involves the growth of plants without soil, delicate care
must be maintained to ensure they maintain the narrow window required for optimum growth. The
Arduino Edge Control can ensure that this window is achieved with minimal manual labour.
Aquaponics can provide even more benefits than conventional hydroponics towards which the Arduino
Edge Control can help match the even higher requirements by providing better control over the
internal process while ultimately reducing production risks.
Mushroom Cultivation: Mushrooms are notorious for requiring the perfect temperature and
humidity conditions to sustain spore growth while also preventing competing fungi from growing.
Thanks to the numerous watermark sensors, output ports and connectivity options available on the
Arduino Edge Control as well as the Arduino IoT Cloud, this precision farming can be achieved on an
unprecedented level.

3.2 Processor
The Main Processor is a Cortex M4F running at up to 64MHz.
3.1 LCD Screen
The Arduino Edge Control provides a dedicated connector (J1) for interfacing with a HD44780 16x2 LCD display
module, sold seperately. The main processor controls the LCD via a TCA6424 port expander over I2C. Data is
transferred over a 4-bit interface. LCD backlight intensity is also adjustable by the main processor.
3.3 5V Analog Sensors
Up to eight 0-5V analog inputs can be connected to J4 for interfacing analog sensors such as tensiometers and
dendrometers. Inputs are protected by a 19V Zener diode. Each input is connected to an analog multiplexer
that channels the signal to a single ADC port.
Each input is connected to an analog multiplexer (MC14067) that channels the signal to a single ADC port. The
main processor controls the input selection via a TCA6424 port expander over I2C.
3.4 4-20mA sensors
Up to four 4-20mA sensors can be connected to J4. A reference voltage of 19V is generated by the MP1542
step-up converter to power the current loop. The sensor value is read via a 220 ohm resistor.
Each input is connected to an analog multiplexer (MC14067) that channels the signal to a single ADC port. The
main processor controls the input selection via a TCA6424 port expander over I2C.
3.5 Watermark Sensors
Up to sixteen hydrostatic watermark sensors can be connected to J8. Pins J8-17 and J8-18 are the common
sensor pins for all the sensors, controlled directly by the microcontroller. Inputs and the common sensor pins
are protected by a 19V Zener diode.
Each input is connected to an analog multiplexer (MC14067) that channels the signal to a single ADC port. The
main processor controls the input selection via a TCA6424 port expander over I2C. The board supports 2
precision modes.
3.6 Latching outputs
Connectors J9 and J10 provide outputs to latching devices like motorized valves. The latching output consists of
dual channels (P and N) through which an impulse or strobe can be sent in either of the 2 channels (to open a
close valve for example). The duration of the strobes can be configured to adjust to the external device
requirement.
The board provides a total of 16 latching ports divided in 2 types:
●
Latching commands (J10): 8 ports for high impedance inputs ( max +/- 25 mA). Connect to external
devices with third-party protection/power circuits. Referenced to VBAT.
●
Latching Out (J9): 8 ports. This outputs includes drivers for the latching device. No external drivers are
needed. Referenced to VBAT.
3.7 Solid State Relays
The board features four configurable 60V 2.5A solid state relays with galvanic isolation available in J11. Typical applications
include HVAC, sprinkler control etc.
3.8 Storage
The board includes both a microSD card socket and an additional 2MB flash memory for data storage. Both are
directly connected to the main processor via a SPI interface.
3.9 Power tree
The board can be powered via solar panels and/or SLA batteries.
4. Board Operation
4.1 Getting started - IDE
If you want to program your Arduino Edge Control while offline you need to install the Arduino Desktop IDE [1]
To connect the Arduino Edge control to your computer, you’ll need a Micro-B USB cable. This also provides
power to the board, as indicated by the LED.
4.2 Getting started - Arduino Web Editor
All Arduino boards, including this one, work out-of-the-box on the Arduino Web Editor [2], by just installing a
simple plugin.
The Arduino Web Editor is hosted online, therefore it will always be up-to-date with the latest features and
support for all boards. Follow [3] to start coding on the browser and upload your sketches onto your board.
4.3 Getting started - Arduino IoT Cloud
All Arduino IoT enabled products are supported on Arduino IoT Cloud which allows you to Log, graph and
analyze sensor data, trigger events, and automate your home or business.
4.4 Sample Sketches
Sample sketches for the Arduino Edge Control can be found either in the “Examples” menu in the Arduino IDE
or in the “Documentation” section of the Arduino Pro website [4].
4.5 Online resources
Now that you have gone through the basics of what you can do with the board you can explore the endless
possibilities it provides by checking exciting projects on ProjectHub [5], the Arduino Library Reference [6] and
the online store [7] where you will be able to complement your board with sensors, actuators and more.
4.6 Board Recovery
All Arduino boards have a built-in bootloader which allows flashing the board via USB. In case a sketch locks up
the processor and the board is not reachable anymore via USB it is possible to enter bootloader mode by
double-tapping the reset button right after power up.
