Applicable to the following Sterling-EWB module part numbers:
Part Number Product Description
453-00014 Sterling-EWB chip antenna module
– Integrated antenna
453-00013 Sterling-EWB U.FL module
– External antenna
All kits contain the following items:
Development Board
The development board has the required Sterling-EWB module soldered onto it and exposes all
available hardware interfaces.
USB Cable
USB cable
– Type A to micro type B.
The cable also provides serial communications via the FTDI USB
– RS232 converter chip on the
board and powers the development board.
External 2.4GHz
dipole antenna
Supplied with development kit part # 455-00031 only.
External antenna, 2 dBi, FlexPIFA (Laird part #001-0014) with integral RF coaxial cable with 100
mm length and IPEX-4 compatible RF connector.
The Sterling-EWB development board is designed to be used directly with the Cypress WICED® SDK. The default
configurations provided in this document will enable operation and software development on this board.
The EWB development board has the following features:
▪
Sterling-EWB 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 (4.4
– 10V) – not supplied. Center positive barrel connector or header for bench supply.
–
(4) AA batteries (not supplied)
▪
Powering the EWB module using a single on-board regulator or separating the MCU and radio supplies to use individual
on-board regulators (SW8)
▪
USB to UART/JTAG bridge (FTDI chip)
▪
Pin headers for measuring current (EWB module only)
▪
Selectable boot options
▪
IO break-out 2.54 mm pitch pin header connectors that bring out all MCU interfaces of the EWB module
– UART, SPI,
QSPI, I2C, SIO [DIO or AIN (ADCs)], I2S, PWM
– and allow for plugging in external modules/sensors
▪
IO breakout 2.54 mm pitch pin header for direct access to Bluetooth radio on the EWB module.
▪
DIP switches on all EWB module IO lines running to peripheral devices on the development board to allow disconnection.
