TXD and RXD pins are used for data, fixed baud rate, support 115200bps. 4.3 Hardware Design 1. It is recommended to use a DC stabilized power supply to power the module. The ripple factor of the power supply should be as small as possible and the module should be reliably grounded; 2. Please pay attention to the correct connection of the positive and negative poles of the power supply, such as reverse connection may cause permanent damage to the module; 3. Please check the power supply to ensure that between the recommended power supply voltages, if the maximum value is exceeded, the module will be permanently damaged; 4. Please check the stability of the power supply, the voltage cannot fluctuate greatly and frequently; 5. When designing the power supply circuit for the module, it is often recommended to reserve more than 30% of the margin, as the whole machine is conducive to long-term stable work; 6. The module should be far away from the parts with large electromagnetic interference such as power supply, transformer, high-frequency wiring; 7. High-frequency digital routing, high-frequency analog routing, and power routing must be avoided under the module. If it is necessary to pass under the module, it is assumed that the module is soldered to the top layer, and copper is laid on the top layer of the module's contact part (all copper and Good grounding), must be close to the digital part of the module and routed in the Bottom Layer; 8. Assuming that the module is soldered or placed on the Top Layer, it is also wrong to arbitrarily route the Bottom Layer or other layers, which will affect the spurs and receiving sensitivity of the module to varying degrees; 9. It is assumed that there are devices with large electromagnetic interference around the module, which will greatly affect the performance of the module. According to the strength of the interference, it is recommended to stay away from the module appropriately. If the situation allows, you can do proper isolation and shielding; 10. It is assumed…

Shenzhen Honeycomb Technologies Company Limited Address: Xinhe Xinxing Industrial Park Block 3 A7 building, Shenzhen RE FCC ID: 2AAUWHBT42A20N To the certification reviewer: We are hereby applying for [full] modular approval of the above-referenced FCC ID, based on compliance with [all] of the criteria as detailed below. Sincerely, [signature] [name] Jensen He [title] General Manager Part 15 Unlicensed Single Modular Transmitter Approval Justification per 15.212 Requirement per 15.212 reference (i) The radio elements of the modular transmitter must have their own RF shielding. The Shielding for RF module will be provided in the host. (ii) The modular transmitter must have buffered modulation/data inputs (if such inputs are provided. All modulation and data inputs are buffered by circuitry on the transmitter chip nRF51822. (iii) The modular transmitter must have its own power supply regulation. Power supply regulation is provided by host at DC 3.3 volts. (iv) The modular transmitter must comply with the antenna and transmission system requirements of §§ 15.203, 15.204(b) and 15.204(c). The antenna is integral. (v) The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with Part 15 parameters. Testing was performed in a stand-alone configuration, as shown in the test setup photos. (vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number. If the FCC ID 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. A sample of the label is provided as an exhibit, showing the FCC identifier of the module. (vii) The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. The module is compliant with all applicable FCC rules. (viii) The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. This module complies with applicable RF exposure requirements.

INTERTEK TESTING SERVICES RF Exposure The equipment under test (EUT) is a module with Bluetooth and 2.4G transmitter functions. It is powered by DC 3.3V. The Bluetooth function and 2.4G transmitter can’t transmit at the same time. This module is only use for battery-powered products. For more detail information pls refer to the user manual. Standalone SAR evaluation for BT function Bluetooth Version: 4.2 (BLE Single mode) Antenna Type: Integral antenna. Antenna Gain: 0dBi. Modulation Type: GFSK The nominal conducted output power specified: -5dBm (+/-3dB) The nominal radiated output power (e.i.r.p) specified: -5dBm (+/- 3dB) The maximun conducted output power for the EUT is -4.70 dBm in the frequency 2480MHz which is within the production variation. The minimum conducted output power for the EUT is -6.21 dBm in the frequency 2402MHz which is within the production variation. The maximun conducted output power specified is -2.0dBm = 0.631mW The source- based time-averaging conducted output power = 0.631 * Duty factor mW (where Duty Factor≤1) = 0.631mW The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.480) mW = 9.53 mW Since the source-based time-averaging conducted output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing. FCC ID: 2AAUWHBT42A20N INTERTEK TESTING SERVICES Standalone SAR evaluation for 2.4G transmitter function Antenna Type: Integral antenna. Antenna Gain: 0dBi. Modulation Type: GFSK The nominal conducted output power specified: -2dBm (Tolerance: +/- 3dB) The nominal radiated output power (e.i.r.p) specified: -2dBm (+/- 3dB) The maximun conducted output power for the EUT is -2.82 dBm in the frequency 2450MHz which is within the production variation. The maximun conducted output power specified is 1.0dBm = 1.259mW The source- based time-averaging conducted output power = 1.259 * Duty factor mW (where Duty Factor≤1) = 1.259mW The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.450) mW = 9.58 mW Since the source-based time-averaging conducted output power is well below the SAR low threshold level, so the EUT is considered to comply with SAR requirement without testing.
