• When switching a resistive load (DC1) having voltage and current
values under the curve, an electrical life of ≥100·103can be
expected.
• In the case of DC13 loads, the connection of a diode in parallel with
the load will permit a similar electrical life as for a DC1 load.
Note: the release time for the load will be increased.

Getting "Started Guide"
Getting started - IDE
If you want to program your 8A.04 while offline you need to install the Arduino Desktop IDE.
To connect the 8A.04 to your computer, you’ll need a USB-C cable. This also provides power to the board, as indicated by the LED.
https://www.arduino.cc/en/Main/Software
Getting started - Arduino Web Editor
All Arduino boards, including this one, work out-of-the-box on the Arduino Web Editor, 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 to start coding
on the browser and upload your sketches onto your board.
https://create.arduino.cc/editor
https://create.arduino.cc/projecthub/Arduino_Genuino/getting-started-with-arduino-web-editor-4b3e4a
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.
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 and the Arduino Library Reference
https://www.arduino.cc/reference/en/
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.

FCC and RED Cautions (Model 8A.04.9.024.8320)
FCC
Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority
to operate the equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may
not cause harmful interference, and (2) this device must accept any interference received, including interference that may
cause undesired operation.
FCC RF Radiation Exposure Statement:
1. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
2. This equipment complies with RF radiation exposure limits set forth for an uncontrolled environment.
3. This equipment should be installed and operated with minimum distance 20cm between the radiator& your body.
Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required
to correct the interference at his own expense.
RED
The product is in compliance with essential requirements and other relevant provisions of Directive 2014/53/EU. This product
is allowed to be used in all EU member states.
