1 Description
The DXYBT021 is a compact, surface mount Bluetooth 4.0 Low Energy (BLE) compliant wireless
module. It integrates an advanced single-chip BLE SoC chip-QN9021 with RF circuit and antenna
in a compact module.
Due to its small size, outstanding performance at very low power consumption and easy modular
handling, the DXYBT021 is leading the way for the new generation of Bluetooth low energy
modules.

Full Modular Approval
This RF Module is full modular approval, it is limited to OEM installation ONLY.
Integration into devices that are directly or indirectly connected to AC lines must add with Class II
Permissive Change. (OEM) Integrator has to assure compliance of the entire end product incl. the
integrated RF Module. Additional measurements (15B) and/or equipment authorizations (e.g
Verification) may need to be addressed depending on co-location or simultaneous transmission
issues if applicable. (OEM) Integrator is reminded to assure that these installation instructions
will not be made available to the end user of the final host device.
With the documented max output power this RF Module meets the FCC SAR Exemption, so it
comply with any applicable RF exposure requirements in its final configuration. The RF Module is
powered by battery, the antenna is PCB antenna and the antenna gain is 2.21dBi. The final host
device, into which this RF Module is integrated" has to be labeled with an auxiliary label stating

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 with the
instructions, may cause harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which 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 following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
-Consult the dealer or an experienced radio/TV technician for help
- This device and its antenna(s) must not be co-located or operating in conjunction with any other
antenna or transmitter.
Hereby, DXY Technology Co.,Ltd. declares that this device is in compliance with the essential
