1. General Description
The S76S integrates ARM Coretex®-M0+ (32-bit RISC core operating at a 32MHz frequency) MCU with LoRaTM
modulation that provides ultra-long range spread spectrum communication and high interference immunity
whilst minimizing current consumption.
S76S can achieve a sensitivity of over -137 dBm. The high sensitivity combined with the integrated +20 dBm
power amplifier yields industry leading link budget making it optimal for any low data rate application requiring
range or robustness. LoRaTM also provides significant advantages in both blocking and selectivity over
conventional modulation techniques, solving the traditional design compromise between range, interference
immunity and energy consumption.
Feature
 Small footprint：13 mm x 11 mm x 1.1 mm
 Preamble detection
 LoRaTM Modem
 Automatic RF Sense and CAD with ultra-fast AFC
 Payload up to 128 bytes with CRC
 +20 dBm constant RF output vs. V supply
 Embedded memories (up to 192 Kbytes of
 Programmable bit rate up to 37500 bps
Flash memory and 20 Kbytes of RAM)
 High sensitivity: down to -137 dBm
 Excellent blocking immunity

6-1. Handling
Handling the module must wear the anti-static wrist strap to avoid ESD damage. After each module is
aligned and tested, it should be transport and storage with anti -static tray and packing. This protective
package must be remained in suitable environment until the module is assembled and soldered onto the
main board.
6-2. SMT Preparation
1. Calculated shelf life in sealed bag: 6 months at<40℃ and <90% relative humidity (RH).
2. Peak package body temperature: 250℃.
3. After bag was opened, devices that will be subjected to reflow solder or other high temperature
process must.
A.
Mounted within: 168 hours of factory conditions<30℃/60%RH.
B.
Stored at≦10%RH with N2 flow box.
4. Devices require baking, before mounting, if:
A.
Package bag does not keep in vacuumed while first time open.
B.
Humidity Indicator Card is >10% when read at 23±5℃.
C.
Expose at 3A condition over 8 hours or Expose at 3B condition over 24 hours.
5. If baking is required, devices may be baked for 12 hours at 125±5℃.

8. FCC statement
Federal Communication Commission Interference Statement
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 and used 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 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.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate this 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.
IMPORTANT NOTE:
Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance 20cm
between the radiator & your body.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
Country Code selection feature to be disabled for products marketed to the US/CANADA
This device is intended only for OEM integrators under the following conditions:

1) The antenna must be installed such that 20 cm is maintained between the antenna and users,
and
2) The transmitter module may not be co-located with any other transmitter or antenna,
3) For all products market in US, OEM has to limit the operation channels in CH1 to CH11 for
2.4G band by supplied firmware programming tool. OEM shall not supply any tool or info to the
end-user regarding to Regulatory Domain change.
As long as 3 conditions above are met, further transmitter test will not be required. However, the
OEM integrator is still responsible for testing their end-product for any additional compliance
requirements required with this module installed
IMPORTANT NOTE
In the event that these conditions can not be met (for example certain laptop configurations or
co-location with another transmitter), then the FCC authorization is no longer considered valid and
the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will
be responsible for re-evaluating the end product (including the transmitter) and obtaining a
separate FCC authorization.
End Product Labeling
This transmitter module is authorized only for use in device where the antenna may be installed
such that 20 cm may be maintained between the antenna and users. The final end product must
be labeled in a visible area with the following: “Contains FCC ID: 2ADWC-S76S”.
Manual Information to the End User
The OEM integrator has to be aware not to provide information to the end user regarding how to
install or remove this RF module in the user’s manual of the end product which integrates this
module.
The end user manual shall include all required regulatory information/warning as show in this
manual.
