KEEP OUT OF REACH OF CHILDREN
. Swallowing may lead to serious injury or death in
as little as 2 hours due to chemical burns and potential perforation of the esophagus.
Immediately see doctor.
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.
Dispose of used batteries according to local regulations and the battery manufacturer's
instructions.
The RTC backup battery holder is soldered to the bottom layer of the RTC module circuit
board. The battery is not accessible from the outside. You should first remove the case top
body to gain access to the Iono MKR circuit boards.
Before opening the Iono MKR Base case, disconnect all power sources and any
connection to external devices, including USB cables.
Use a non-conductive pin or small tool to help extract the battery from its holder. Insert the
new battery with a gentle push. You don't need tools to insert the battery. The battery is
held into place by a spring contact.
Be sure to insert the battery so that the positive (+) terminal of the battery is in contact with
the outer body of the battery holder, and the negative (-) terminal is in contact with the
contact pad of the circuit board, as shown in the photo below.
Reversing the battery polarity may damage the product.
The real time clock will reset its time immediately when the RTC backup battery is
disconnected.
ATECC608 secure element
Iono MKR can be shipped with an optional, factory-installed hardware secure element
chip, the ATECC608 from Microchip. The ATECC608 is connected to the to the Arduino
MKR via the I2C bus (address: 0x60).
Its key features are:
✓
Cryptographic co-processor with secure hardware-based key storage
✓
Protected storage for up to 16 Keys, certificates or data
✓
Hardware support for asymmetric sign, verify, key agreement – ECDSA: FIPS186-3
Elliptic Curve Digital Signature
✓
ECDH: FIPS SP800-56A Elliptic Curve Diffie-Hellman
✓
NIST standard P256 elliptic curve support
✓
Hardware support for symmetric algorithms
