Ra-01SC Specification V1.1 6. Design guidance 6.1 Application Circuit （1） In addition to the SPI interface, the communication interface with the master MCU must also connect BUSY/DIO1 to the IO port of the master MCU （2） If the antenna is soldered on the main control board, it is recommended to reserve a Π matching circuit at the antenna interface. 6.2 Recommended module package design size Note：This is the package drawing of the Ra-01SC module.
Ra-01SC Specification V1.1 6.3 Antenna installation (1) Ra-01SC has one spring antenna, the antenna can not be replaced by other authorized antennas； (2) In order to meet the best antenna effect，the location of the antenna assembly should be far away from the metal parts； (3) The antenna installation structure has a great influence on the performance of the module.
Ra-01SC Specification V1.1 6.5 GPIO （1） There are some GPIO ports on the periphery of the module. If you need to use a 10-100 ohm resistor in series with the IO port, it can suppress overshoot and make the levels on both sides more stable, which is helpful for EMI and ESD. For the pull-up and pull-down of special IO ports, please refer to the instructions in the specification, which will affect the startup configuration of the module; （3） The IO port of the module is 3.3V.
Ra-01SC Specification V1.1 Different between LLCC68 and SX1262/SX1268： (1) SX1262/SX1268 support spreading factor SF5,SF6,SF7,SF8,SF9,SF10,SF11,SF12； SX1262/SX1268 can set spreading factor and receiving bandwidth: LoRa@ Rx/Tx，BW = 7.8 - 500 kHz, SF5 TO SF12,BR=0.018-62.5 Kb/S (2) LLCC68 support spreading factor SF5,SF6,SF7,SF8,SF9,SF10,SF11.

FCC WARNING 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.
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The availability of some specific channels and/or operational frequency bands are country dependent and are firmware programmed at the factory to match the intended destination. The firmware setting is not accessible by the end user.
Requirement per KDB996369 D03 2.2 List of applicable FCC rules List the FCC rules that are applicable to the modular transmitter. These are the rules that specifically establish the bands of operation, the power, spurious emissions, and operating fundamental frequencies. DO NOT list compliance to unintentional-radiator rules (Part 15 Subpart B) since that is not a condition of a module grant that is extended to a host manufacturer. See also Section 2.
This limited module procedure is also applicable for RF exposure evaluation when it is necessary to demonstrate compliance in a specific host. The module manufacturer must state how control of the product into which the modular transmitter will be installed will be maintained such that full compliance of the product is always ensured.
Explanation: The EUT has one spring antenna, the antenna can not be replaced by other authorized antennas. 2.8 Label and compliance information Grantees are responsible for the continued compliance of their modules to the FCC rules. This includes advising host product manufacturers that they need to provide a physical or e-label stating “Contains FCC ID” with their finished product. See Guidelines for Labeling and User Information for RF Devices – KDB Publication 784748.
circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed. Explanation: The module without unintentional-radiator digital circuity, so the module does not require an evaluation by FCC Part 15 Subpart B. The host shoule be evaluated by the FCC Subpart B.
