RAK13400 Bluetooth Module Datasheet Overview Description The RAK13400 is a highly integrated Bluetooth 5 module with a UART (Universal Asynchronous Receiver/Transmitter) interface. The module is designed base on RTL8761BTV-CG from Realtek,has BT Protocol Stack ,BT Baseband,modem and BT RF in a single module. The RAK13400 provides a low power and ultra-low cost BLE solution for wireless transmission applications. It can be used in conjunction with other products from Rakwirekess like RAK7268C to achieve more applications. Features Bluetooth 5 specification compliant Supports Bluetooth Low Energy (BLE) Maximum output power: TX +10dBm for BLE Receive sensitivity: -98 dBm(BLE Minimum)
-106dBm (125K BLE long range Minimum) HS-UART interface for Bluetooth data transmission compliant H5 specification Support rate2Mb/s(LE 2M),1Mb/s(LE 1M),500Kb/s(LE Coded),125Kb/s(LE Coded) Typica Antenna Peak Gain: 1.8 dBi (@2442MHz) Supply voltage :2.97 to 3.63V Temperature range:0 C to +70 C Module size:20mmx30mm Specifications Overview Mounting The RAK13400 Bluetooth module can be mounted to a board which have a standard Wiscore slot . Figure 1 shows the mounting mechanism of the RAK13400 on a RAK7268C . Figure 1: RAK13400 Bluetooth Module Mounting Pin Definition The RAK13400 Bluetooth module comprises a standard Wiscore connector. The Wiscore connector allows the RAK13400 module to mounted to a board which have a standard Wiscore slot such as RAK7268C. The pin order of the connector and the pinout definition is shown in Figure 2.

Operation is subject to the follow ing tw o 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 Caution:
Changes or modifications not expressly approved by the part responsible for compliance could void the user's authority to operate the equipment. FCC RF Radiation Exposure Statement Caution: This Transmitter must be installed to provide a separation distance of at least 20 cm from all persons. FCC Statement:
"This equipment has been tested and found to comply w ith 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 w ith the instructions, may cause harmful interference to radio communications. How ever, there is no guarantee that interference w ill not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, w hich 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 follow ing measures:
Reorient or relocate the receiving antenna. Increase the separation betw een the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to w hich the receiver is connected. Consult the dealer or an experienced radio/TV technician for help."
The U.FL connector antenna has been approved for the modular. The maximum antenna gain is 4.7dBi. For situations w here the host manufacturer is responsible for an external connector, the integration instructions shall inform the installer that a unique antenna connector must be used on the Part 15 authorized transmitters used in the host product. IC statement:
This device complies w ith Industry Canada licence-exempt RSS standard(s). Operation is subject to the follow ing tw o conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Le prsent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorise aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible d'en compromettre le fonctionnement. This equipment complies w ith ISED radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated w ith minimum distance 20cm betw een the radiator&
your body.This transmitter must not be co-located or operating in conjunction w ith any other antenna or transmitter located or operating in conjunction w ith any other antenna or transmitter. Cet quipement est conforme avec les limites dexposition la radiation de lISED mises dans un environnement contrl. Cet quipement devrait tre install et fonctionnel avec un minimum de distance entre le radiateur et votre corps dau moins 20 cm. Ce transmetteur ne doit pas tre co-situ prs dune autre antenne ou en conjonction avec un autre transmetteur. The proposed FCC IC label format is to be placed on the module. If it is not visible w hen the module is installed into the system, Contains FCC ID: 2AF6B-RAK13400, Contains IC: 25908-RAK13400 shall be placed on the outside of final host system. Labelling This radio transmitter [25908-RAK13400] has been approved by Innovation, Science and Economic Development Canada to operate w ith the antenna types listed below , w ith the maximum permissible gain indicated.
