.1. General Introduction
BT-V2.0(BK3513) is a Bluetooth 2.1 class 2 modules which is a high performance, cost
effective, low power and compact solution. The Bluetooth class 2 module provides a complete
2.4GHz Bluetooth system based on BK3513 chip which is a single chip radio and baseband
IC for Bluetooth 2.4GHz systems. This module is fully compliant to Bluetooth v2.1 for audio
communications.
The AC410x family is a low-power, high-performance microprocessor with 96KB SRAM,
which incorporates a 32-bit RISC CPU, a high-speed digital signal processor(DSP) and rich
peripheral circuits. Key features of the AC410x family include:
---- 36 Programmable GPIO.
---- Support Watch Dog (WDT) and RTC.
---- 24 Interrupt Sources and 4 interrupt priority level.
---- Support idle/standby/sleep low power mode and IO wakeup.
---- Two 8bit and two 16bit Timer/Counters, supports PWM mode and capture function.
---- 16bit stereo DAC with Headphone Amplifier.
---- 16bit ADC with Microphone Amplifier.
---- Two full-duplex UART, and UART0 supports DMA.
---- Two SPI controller supports master and slave, and DMA.
---- Two SD master controller supports DMA.
---- One full speed USB2.0 controller which supports master and slave.

● If y
ou want to use the MIC function, in order to achieve the best sound effects,
please don't take MICAnd SPK is placed in the same plane, preferably vertically
placed
● Full metal shell will greatly shorten the Bluetooth transmission distance
● Bluetooth antenna below PCB plate not copper

F
his equipment has been tested and found to comply with the limits for Part 15 of the FCC rules.
T
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 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 to an outlet on a circuit different from that to which the receiver
is connected.
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.
N
ote: Modifications to this product will void the user’s authority to operate this equipment.
F Radiation Exposure Statement:
R
1.This Transmitter must not be co‐located or operating in conjunction with any other antenna or
transmitter.
2.This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20
centimeters between the radiator and your body.
F
CC Information to OEM integrator
The OEM integrator has to be aware not to provide information to the end user regarding how to
install or remove this RF module in the user manual of the end product.
The user manual which is provided by OEM integrators for end users must include the following
information in a prominent location.
1.To comply with FCC RF exposure compliance requirements, the antenna used for this transmitter
must be installed to provide a separation distance of at least 20 cm from all persons and must not
be co ‐ located or operating in conjunction with any other antenna or transmitter, except in
accordance with FCC multi‐transmitter product procedures.
2. Only those antennas with same type and lesser gain filed under this FCC ID number can be used
with this device.
3. The regulatory label on the final system must include the statement: “Contains FCC ID: 2ACP4-
SPBPT or using electronic labeling method as documented in KDB 784748.
4. The final system integrator must ensure there is no instruction provided in the user manual or
customer documentation indicating how to install or remove the transmitter module except such
device has implemented two‐ways authentication between module and the host system
