Ezurio BL654 Development Kits
Ezurio BL654 Development Kits offer rapid wireless connectivity prototyping and provide multiple options for BLUETOOTH® Low Energy (BLE) plus Near Field Communication (NFC) application development. The development kits are designed to support the development of applications and software for the BL654 series of BLE modules. These modules feature Ezurio's innovative event-driven programming language – smartBASIC, or can be used with the Nordic SDK for C development.Features
- BL654 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 (2.5V to 5.5V)
- AAA batteries (three AAA battery holder fitted on underside of development board)
- USB (micro-USB, type B) –for direct use of BL654 USB interface as well
- USB to UART bridge (FTDI chip)
- BL654 UART Interfaces
- 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)
- Atmel MCU by use of an analog switch to route the BL654 UART (for those customers working with Nordic SDK)
- Current measuring options (BL654 module only)
- Pin header (Ammeter)
- 10R Series resistor for differential measurement (oscilloscope)
- IO break-out 2.54 mm pitch pin header connectors (plated through-holes) that bring out all interfaces of the BL654 module – UART, SPI, QSPI, I2C, SIO [DIO or AIN (ADCs)], PWM, FREQ, NFC – and allow for plugging in external modules/sensors
- Power supply option for coin-cell (CR2032) operation of the BL654 module ONLY (not development board)
- Pin headers jumpers that allow the on-board sensors to be disconnected from BL654 module
- Four on-board sensors
- Analog output temperature sensor
- I2C device (RTC chip)
- SPI device (EEPROM)
- QSPI device (Flash IC)
- Four buttons and Four LEDs for user interaction
- One reset button (via an analog switch)
- NFC antenna connector on-board development board for use with supplied flexi-PCB NFC antenna
- Optional external 32.768 kHz crystal oscillator and associated load capacitors
- Optional external serial (SPI) flash IC
- Optional external serial (QSPI) flash IC
- Access to BL654 JTAG – also known as Serial Wire Debug (SWD) Interface
- On-board SWD (JTAG) programmer circuitry
- smartBASIC runtime engine FW upgrade capability
- Via UART (using the FTDI USB-UART)
- Via SWD (JTAG) using on-board JTAG programmer circuitry on the BL654 Development Kit
- smartBASIC application upgrade capability
- Via UART (using the FTDI USB-UART)
- Via OTA (Over-the-Air)
