3 – Microcontroller (Freescale Kinetis, MKL25Z128VLH4).
4 – Bluetooth Module (Microchip, RN4020-V/RM).
1 – The Barcode scanner consists of two major components, the imager engine and the
decoder board. The imager engine contains a CMOS imaging sensor and separate
external illumination. The decoder board contains a microprocessor with external RAM
and FLASH used to capture and process images from the image engine.
2 – The RFID transceiver and antenna consist of an NXP RFID transceiver part number
CLRC66301HN,551 and a custom loop antenna. The loop antenna is essential a flex
circuit that mounts around the image engine and interfaces to the circuit board housing
the CLRC663 via a flex circuit and connector on the interface board. The antenna is
shielded on both along the length of the flex tail up to the loop portion. The shield is tied
to the ground trace on the antenna which is tied directly to the ground of the circuit
board.
3 – The Microcontroller on the interface board controls the power and communications
links between itself and both the barcode scanner and the RFID transceiver.
The communication link between the barcode scanner and the microcontroller is via a
RS-232 interface.
The communication link between the RFID transceiver and the microcontroller is via a
SPI interface.
The microcontroller monitors PIO for external input and output control, interfaces to the
base station via a Bluetooth communications link, controls the barcode scanner and
communications, controls battery charging, and controls the RFID transceiver and
communications.
