Ezurio DVK-BL652 Development Kit
Ezurio DVK-BL652 Development Kit provides a platform for rapid wireless connectivity prototyping. The kit provides multiple options for the development of BLUETOOTH® Low Energy (BLE) plus Near Field Communication (NFC) applications. The Ezurio BLE development kit is designed to support the rapid development of applications and software for the BL652 series of BLE modules featuring Ezurio’s innovative event-driven programming language (smartBASIC).
The BL652-SA-xx comes with Bluetooth Smart v4.2, an NFC module, and an integrated antenna featuring smartBASIC. The BL652-SC-xx comes with Bluetooth Smart v4.2, an NFC module, and an external antenna featuring smartBASIC (FCC).
Features
- BL652 series module soldered onto the development board
- The following power supply options for powering the development board
- USB (micro-USB, type B)
- External DC supply (7V to 12V)
- AAA batteries (three AAA battery holder fitted on the underside of the development board)
- Regulated 3.3V for powering the BL652 module
- Optional regulated 1.8V for powering the BL652 module via a selection switch
- Power supply option for coin-cell (CR2032) operation of the BL652 module ONLY (not development board)
- USB to UART bridge (FTDI chip)
- BL652 UART can be interfaced to
- USB (PC) using the USB-UART bridge (FTDI chip)
- External UART source (using IO break-out connectors J1 when the development board is powered from a DC jack or AAA batteries)
- Arduino connector by the use of an analog switch to route the BL652 UART
- Current measuring options (BL652 module only)
- Pin header (Ammeter)
- Current shunt monitor IC (voltmeter or oscilloscope)
- Series resistor for differential measurement (oscilloscope)
- IO break-out 2.54mm pitch pin header connectors (plated through-holes) that bring out all interfaces of the BL652 module
- UART
- SPI
- I2C
- SIO [DIO or AIN (ADCs)]
- PWM
- FREQ
- NFC
- Allows for plugging in external modules/sensors
- Pin headers jumpers that allow the onboard sensors (I2C sensor, LEDs, Arduino SPI interface, etc.; and the USB UART FTDI bridge)
- Disconnected from the BL652 module (by removing jumpers)
- Three onboard sensors
- Analog output temperature sensor
- I2C device (RTC chip)
- SPI device (EEPROM)
- Two buttons and two LEDs for user interaction
- NFC antenna connector onboard development board for use with supplied Flexi-PCB NFC antenna
- Optional external 32.768kHz crystal oscillator
- Not required for the operation of the BL652
- Disconnected by open solder-bridges by default
- Optional external serial (SPI) flash IC
- Not required for the operation of the BL652
- Disconnected by open solder-bridges by default
- One analog buffer (provides a 3.3:1 attenuation) is used when an analog source is at 5 volts into the development board
- Arduino connectors – Allow for plugging of Arduino shield boards
- Arduino connector test points
- All Arduino connector signals brought out to plated through-holes (2.54mm pitch)
- Allow any Arduino connector signal (D0-D13 or A0-A5) to be connected to any BL652 module using fly leads for maximum flexibility
Arduino connector signals wired to BL652 via headers or series resistors
- Arduino connectors orientation at 90 degrees to the development board long dimension
- Allows for larger Arduino shields to hang off the side of the development board so that it is not interfering with the mounted external antenna or the BL652 module (the BLE chip antenna)
- Access to BL652 JTAG – also known as Serial Wire Debug (SWD) Interface
- Onboard SWD (JTAG) programmer circuitry
- smartBASIC runtime engine FW upgrade capability
- Via UART (using the FTDI USB-UART)
- Via SWD (JTAG) using onboard JTAG programmer circuitry on the DVK-BL652
- smartBASIC application upgrade capability
- Via UART (using the FTDI USB-UART)
- Via OTA (Over-the-Air)
