Block Diagram
The GCC-BTM002S module integrates a 32-bit BLE MCU TLSR8251 , 24MHZ crystal,
PCB antenna, Uart and some GPIOs.
The TLSR8251 integrates a power-balanced 32-bit MCU, BLE/802.15.4/2.4GHz
Radio, 32kB SRAM, 512kB internal Flash, 14bit ADC with PGA, analog and digital
microphone input, stereo audio output, 6- channel PWM (1-channel IR/IR FIFO/IR
DMA FIFO), one quadrature decoder (QDEC), abundant and flexible GPIO
interfaces, and nearly all the peripherals needed for IoT (Internet of Things)
and HID (Human Interface Devices) application development (e.g. Bluetooth Low
Energy and IEEE 802.15.4). The TLSR8251 also includes multi-stage power
management design allowing ultra-low power operation and making it the ideal
candidate for wearable and power-constraint applications.
With the high integration level of TLSR8251, few external components are
needed to satisfy customers’ ultralow cost requirements.

Module Placement Recommendations
Effect of Metals Nearby
Another significant source of issues for RF is the presence of metal near the antenna. Metal also produces an effect on the electric field and change the radiation pattern or create nulls where no signal is received. Any nearby metal may affect the antenna significantly and reduce the range. It’s therefore critical to keep any metal way at least 30mm from the module. Your design should place any metal as far away as possible.
Recommended Operating Conditions
The operating conditions are the physical parameters that the chip can operate within.

Model Information
Warning
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.
- This device must accept any interference received, including interference that may cause undesired operation.
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.
- Consult the dealer or an experienced radio/TV technician for help.
MODIFICATION: Any changes or modifications not expressly approved by the grantee of this device could void the user’s authority to operate the device.
To satisfy FCC exterior labeling requirements, the following text must be placed on the exterior of the end product. “Contains Transmitter module FCC ID: 2A979GCC-BTM002S.
