FCC Interference Statement for Class B devices.
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. • Consult the dealer or an experienced
radio/TV technician for help.

＜Caution＞
This evaluation board is intended for use for engineering development, demonstration, or evaluation purpose only. Persons handling this product must have rich electronics knowledge and rich engineering
practice. Sensyst does not consider for this product to be a finished end-product fit for general consumer use. The products incorporated this board are not appropriate for resales.
The coaxial RF adapters suitable for Hirose MS-156C, and the debug emulator with half pitch 10 pin cable
aren’t included in this KIT. If need for your evaluation or development, please prepare yourself.
IDE is required for developing user applications. Keil μVision or IAR Embedded Workbench is available.
1 Features
The SAPPHIRE evaluation board includes Toshiba Bluetooth LE IC complies with Bluetooth 5, low energy single-mode radio and has the following features.
[Radio]
Complies with Bluetooth 5, low energy single-mode radio operates at 2402 MHz to 2480 MHz. (ISB Band 2400~2483.5MHz)
Toshiba Qualified Bluetooth protocol stacks such as GATT, SMP and HCI are stored in the Bluetooth LE IC.
Bluetooth Device Address, uniquely radio identifier is stored in the Bluetooth LE IC.
Maximum communication distance is over 600 m with the pattern antenna on this board. (Max TX output power :+8 dBm, Min RX Sensitivity LE Coded S=8: -105 dBm)
Hirose MS-156C RF switch connector for radio evaluation is on this board. If needed for radio evaluation, please prepare suitable RF coaxial adapter such as MS-156R-HRMJ-1 yourself.
[Power]
USB bus powered is supported. Built-in LDO device produce a 3.3 V power supply to the ICs from Vbus 5 V.
Pin headers for external power supply such as coin battery are also available.
Pure current (VBAT+VDDIO) of the Bluetooth LE IC can be measured at the pin headers on the board.
[GPIO]
All 18 GPIOs of the Bluetooth LE IC can be directly contacted at the pin headers on this board.
[Peripheral]
Either HCI mode or User-App mode can be selected by the configuration of Mode Select Pin.
Silicon labs CP2104 device, USB-UART bridge IC enables UART communication with PC and Bluetooth LE IC.
512 Kbit EEPROM device is on this board. The SAPPHIRE-681FSG boots up from this EEPROM device for User-App mode.
Toggle switch for GPIO0(wakeup0) and GPIO15(wakeup1).
A push switch, a dip switch, a LED and a volume for user application can be connected to the any GPIOs with wire cables.
Half pitch 10 pin connector for SWD debugging and programming.
USB-SWD bridge function is available. This provides CMSIS-DAP, a standardized way to access the Coresight Debug Access Port (DAP) of the ARM Cortex microcontroller via USB.
Grove Universal 4 pin connector can be mounted on this board for connecting the various I2C shield modules.

3 Getting Started for HCI mode operation
(1) Figure below is for HCI mode operation setting. Check the jumper position on this board so that
it can be communicated with a Windows PC via virtual COM port. (The picture below is a
SAPPHIRE-680FSG)
(2) Get the latest version of the CP210x USB to UART Bridge VCP Driver on the Silicon Labs
website: http://www.silabs.com/interface-software and install this to the PC.
(3) Connect the SAPPHIRE Evaluation board to the PC using standard USB Type A Male to Mini
B Male Cable to supply the power to the board.
(4) The CP210x device will appear as a COM port on Windows device manager. As a virtual COM
port, the CP210x functions identically to a real COM port from the reference point of both the
host application and the serial device.
(5) Bluetooth LE IC starts HCI mode operation. Using host application software such as
HCIScript, you can command to the Bluetooth LE IC on this board and download user
applications to the non-volitile memory. Please access TDSC site below and get the HCIScripts
and sample applications.

4 Getting Started for user-app mode operation
(1) Figure below is for user-app mode operation setting. Check the jumper position to run a user
application program. Jumper sockets among SDA and GPIO(8) and among SCL and GPIO(7)
are not required for SAPPHIRE-680FSG.
