INTRODUCTION

Overview

FSC-BT1026D it is a Bluetooth dual-mode module series. It supports a Bluetooth Low Energy and compliant system for audio and data communication.
FSC-BT1026D integrates an ultra-low-power DSP and application processor with embedded flash memory, a high-performance stereo codec, a power management subsystem, I2S, LED drivers and ADC I/O in a SOC IC.
Both cores use external flash to execute code, making it easy for user to differentiate products from new features without delaying the development
By default, FSC-BT1026D module is equipped with powerful and easy-to-use Feasycom firmware. It’s easy to use and completely encapsulated. Feasycom firmware enables users to access Bluetooth functionality with simple ASCII commands delivered to the
module over serial interface – it’s just like a Bluetooth modem.
Therefore, FSC-BT1026D provides an ideal solution for developers who want to integrate Bluetooth wireless technology into their design.

Module Pin Notes:

The internal output of 1.8 V power supply provides maximum 30mA current, and the specific use method can see the application circuit diagram
Provid voltage reference to I/O, such as：PIO, UART, SPI, I2S, PCM,etc
Regulator enable input. Can also be sensed as an input.
Regulator enable and multifunction button. A high input (tolerant to VBAT) enables the on-chip regulators, which can then be latched on internally and the button used as a multifunction input.
Reset this pin for at least 100ms after VBAT_IN and VDD_IO is up, then set this pin for more than 100 ms (can use MCU/button/delayed circuit to achieve this) to start the system.
Using USB function and Lithium battery charging function, the pin should connect 5V voltage
1, Alternate I2C function
2, I2C Serial Clock and Data.
It is essential to remember that pull-up resistors on both SCL and SDA lines are not provided in the module and MUST be provided external to the module.
For customized module, this pin can be work as I/O Interface.
When the Pin33(BAT_IN) with a 3V3~4V2 this pin outputs 2V8 ~ 3V0 (maximum current: 50mA)
when the No. 39 PIN (VCC_CHG) with a 5V input pin, this pin outputs 3.2V ~ 3.4V (maximum current: 50mA)
Analog input voltage range: 0~ 1.8V
By default, this PIN is an empty feet. This PIN can connect to an external antenna to improve the Bluetooth signal coverage. To use an external antenna, the position of an 0Ω resistor needs to be changed to disconnect the on-board antenna and connect to the external antenna; Or contact Feasycom for modification.

For more information on testing, please contact the manufacturer.
Additional testing, Part 15 Subpart B disclaimer
The modular transmitter is only FCC authorized for the specific rule parts (FCC Part 15.247) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed when contains digital circuity.

FCC Statements
(OEM) The integrator has to assure compliance of the entire end product incl. the integrated RF Module. For 15 B (§15.107 and if applicable §15.109) compliance, the host manufacturer is required to show compliance with 15 while the module is installed and operating.

Furthermore, the module should be transmitting and the evaluation should confirm that the module’s intentional emissions (15C) are compliant (fundamental/out-of-band). Finally, the integrator has to apply the appropriate equipment authorization (e.g. Verification) for the new host device per definition in §15.101.The integrator is reminded to assure that these installation instructions will not be made available to the end-user of the final host device. The final host device, into which this RF Module is integrated” has to be labelled with an auxiliary label stating the FCC ID of the RF Module, such as “Contains FCC ID: 2AMWOFSC-BT1026D “This device complies with part 15 of the FCC rules.

Operation is subject to the following two conditions:

this device may not cause harmful interference, and
this device must accept any interference received, including interference that may cause undesired operation.”

“Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.”

The Integrator will be responsible for satisfying SAR/ RF Exposure requirements, when the module is integrated into the host device.

Module statement
The single-modular transmitter is a self-contained, physically delineated, component for which compliance can be demonstrated independent of the host operating conditions, and which complies with all eight requirements of § 15.212(a)(1) as summarized below.

The radio elements have the radio frequency circuitry shielded.
The module has buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal.
The module contains power supply regulation on the module.
The module contains a permanently attached antenna.
The module demonstrates compliance in a stand-alone configuration.
The module is labeled with its permanently affixed FCC ID label.
The module complies with all specific rules applicable to the transmitter, including all the conditions provided in the integration instructions by the grantee.
The module complies with RF exposure requirements.

NOTE : This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.

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 into an outlet on a circuit different from that to which the receiver is connected.
