Kit Operation
Figure 3-2. BLE Module Block Diagram
This kit includes two modules boards. These boards act as a basic breakout board for the
CY8C4247LQI-BL483 and CYBL10563-56LQXI BLE silicon. The PSoC 4 BLE and PRoC BLE
Modules are identical except for the silicon. In addition to including the PSoC 4 BLE and PRoC BLE
devices, the module boards also contain the BLE passives (resistors, capacitors, external crystals,
and antenna-matching network), an onboard antenna, and headers for connecting to the baseboard.
The BLE dongle is the host's wireless interface for the BLE device or project on the baseboard. The
dongle has a PRoC BLE device, to allow BLE connection with other kits. It also contains a
PSoC 5LP, to be used as an onboard programmer or debugger, and for the USB-Serial interface, as
shown in Figure 3-3.
The dongle has a USB A-type plug to connect the PSoC 5LP to the USB port of the host PC. The
PSoC 5LP then communicates with the PRoC BLE device over UART or multiplexed I
2
C or an SPI
bus. The board also features a user LED, a user switch, and a reset switch for the PRoC BLE
device. The dongle is powered directly through the USB port (VBUS) at 5.0 V.
The BLE dongle can also be used as a standalone programmer to program and debug other PSoC
devices (outside the dongle board) using SWD, and as a USB-Serial bridge after removing the
resistor between the SWD pins of PSoC 5LP and PRoC BLE.
