Important Information for OEM Integration
This device is intended for OEM integration only and cannot be sold to the general public. Manufacturers must include the required FCC/IC statements on the final product and in the installation manual.
Supply Voltage Specifications
The module requires specific voltage ranges for proper operation:
- VBAT: 3.0V (Min), 3.6V (Typ), 4.8V (Max)
- VDDIO: 1.71V (Min), 1.8V or 3.3V (Typ), 3.63V (Max)
- Operating Temperature: -40°C to +85°C
Antenna Design Requirements
Designers must adhere to the following specifications when designing the antenna:
- Type and Size: The antenna must be the same type as specified in the antenna specifications and match the size defined in the Gerber file.
- Gain: The peak antenna gain must be less than the application value of 1.4dBi.
- Emission Levels: Spurious emission degradation must be less than 3dB compared to the worst-case report used for the application.
All antenna design reports must be sent to Venstar.
Regulatory Compliance
This device contains the following identifiers:
- FCC ID: MUH-DAIKIN1P2
- IC ID: 12547A-DAIKIN1P2
The device complies with Part 15 of the FCC Rules. Operation is subject to the conditions that the device may not cause harmful interference and must accept any interference received.
Practical help
Before use
- Verify supply voltage (VBAT 3.0-4.8V, VDDIO 1.71-3.63V)
- Ensure antenna type matches specifications
- Confirm antenna size matches the Gerber file
- Measure peak gain (must be < 1.4dBi)
- Measure spurious emissions (degradation < 3dB)
Model compatibility
- For OEM integration only; not for sale to the general public.
