(BLE) 4.2 Module Model MB-N2 Data Sheet Date: Nov 2016 Version: 0.1 (Initial Draft) E-mail: info@redbear.cc Website: www.redbear.cc Red Bear Company Limited assumes no responsibility for any errors which may appear in this manual. And reserves the right to alter the hardware, software, and/or specifications detailed here at any time without notice. 1 www.redbear.cc Document Date Modification Initials release Version 0.1 2016/11/01 Initial version Ping 2 Description www.redbear.cc MB-N2 BLE module houses the Nordic nRF52832 SoC with an on-board chip antenna tuning for great performance and low power consumption. MB-N2 offers all Bluetooth low energy features: radio, stack, profiles and application space for customer applications, so no external processor is needed. The module also provides flexible hardware interfaces to connect sensors, simple user interfaces or even displays directly to the module. MB-N2 can be powered directly with a standard 3V coin cell batteries or pair of 3A batteries. In lowest power sleep mode, it consumes only 0.4uA and will wake up in few hundred microseconds. For the nRF52832 SoC, refers to the nRF52832 Product Specification and the SDK is available from the Nordic Semiconductor website. Key Features

FCC Statement 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. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 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. 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: 2AKGS-MBN2 Or Contains FCC ID: 2AKGS-MBN2 When the module is installed inside another device, the user manual of the host must contain below warning statements;
1. 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.
(2) This device must accept any interference received, including interference that may cause undesired operation. 2.
