ECB-PR70
Notice：
The adapter requires DC5V @3A.
Be sure to install a custom heatsink when running under a
l
arge load.
Must be used under normal temperature conditions.
External power supply is required for larger loads.
Must use the standard wifi antenna.
Be careful not to reverse the power of the serial port and GPIO,
o
therwise it will damage the motherboard.
Usage Step：
1.From the website https://github.com/leezsbc/
resources / wiki / Leez-P710 download the appropriate
i
mage.
2. Burn the operating system to SD card or eMMC, (see the
o
fficial website for the burning method
Relevant detailed guidelines https://leez.lenovo.com).
3. Connect the appropriate peripherals.
4. USB 5V power connected to the power adapter.

FCC Modular Usage Statement
2.2 List of applicable FCC rules
FCC CFR Title 47 Part 15 Subpart C Section 15.247
FCC CFR Title 47 Part 15 Subpart E Section 15.407
2.3 Summarize the specific operational use conditions
This transmitter must not be co‐located or operating in conjunction with any other antenna or transmitter.
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.
Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could
void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed
andused in accordance with the instructions, may cause harmful interference to radio communications. However, there
is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
‐ Reorient or relocate the receiving antenna.
‐ Increase the separation between the equipment and receiver.
‐Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
‐Consult the dealer or an experienced radio/TV technician for help.
Antennas : The antenna design frequency bandis:2.4G/5.8GWIFI segment. 2400-2480MHz
5100-5850MHz Radiantefficiency2400-2480MHz:>45%
5100-5850MHz：＞30％
Label and compliance information If this certified module is installed inside the host device, then the outside
of the host must be labeled with “ Contains FCC ID: A5M-ECBPR70”.
2.6 RF exposure considerations
This modular complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This transmitter
must not be co-located or operating in conjunction with any other antenna or transmitter. This modular must be installed
and operated with a minimum distance of 20 cm between the radiator and user body.
2.7 Antennas
Integral antenna with antenna gain 2dBi for frequency range from 2402MHz to 2480MHz and
1.3dBi for frequency range from 5180MHz to 5240MHz & 5745MHz to 5825MHz .The antenna is a detachable FPC
antenna. Please use the same type of antenna and the antenna gain should not exceed the specified value. Do not
replace other types of antennas without permission.
Label and compliance information
If the FCC identification number is not visible when the module is installed inside another device, then the outside of the
device into which the module is installed must also display a label referring to the enclosed module. This exterior label
can use wording such as the following: “Contains Transmitter Module FCC ID: A5M-ECBPR70”
