What's in the box?
Micro RWD Universal Base Board works with all of the IB Technology Micro RWD
module types. The board provides the antenna, power supply regulation and RS232
interface to the Micro RWD module itself.
Supported Transponders – Philips Mifare, ICODE
Features:
- 24-pin DIP socket for Micro RWD Module (See below)
- LEDS for visual status indication
- Selectable PCB and coil based antenna for 13.56MHz and 125kHz operation
(13.56 MHz antenna is etched into the circuit board.
External antenna
must be used for 125 kHz. Some assembly required.)
- Voltage regulation allowing 9-12v DC power supplies to be used.
- Additional connectors have all the Micro RWD module electrical signals available.
-
Optional USB port is available.
The Universal Base Board data sheet details the link settings, circuit diagram
and interface connections. Gerber files for the PCB layout (useful for the antenna
dimensions) are available on request. Please note that the Universal Base Board
does not have the USB module or a Micro RWD module fitted as standard. These items
are supplied separately.
Info and Software links:
Supported Transponders – Philips ICODE SLI (ISO15693)ICODE SLI has 128 bytes of read/write memory with a unique factory-programmed
serial number at the first locations in memory.
13.56 MHz, 1024 bit (128 byte) read/write passive RFID transponder.
ICODE SLI is an ISO15693 compliant transponder that has fast access and
read/write times and has been designed to be used in “Smart Labels” packages for
asset tracking and other applications.
The higher frequency operation allows communication rates up to 53 kbaud. The
flexible memory structure and the requirement for only a few turns of wire or
printed foil tracks for the antenna makes ICODE SLI a popular and low-cost
read/write transponder type.
Memory is organized as 4-byte blocks with the first two blocks containing a
factory programmed 8-byte unique serial number (UID).
Data can be read/written to 4-byte Blocks or multiples of Blocks in one
operation.

Supported Transponders – Philips Mifare 1k (S50) (ISO 14443A)
Mifare 1k has 1024 bytes of read/write memory (4k version has 4096 bytes of
memory) which is divided up into 16 segments (40 on 4k version), each secured by
programmable key codes.
13.56 MHz, 8192 bit (1024 byte) read/write passive RFID transponder. Large
memory size is organized as 16 sectors, each with it’s own security key codes
and access conditions. This allows entirely different applications to use
separate memory sectors with unique security keys. In addition, the Mifare cards
use a three-pass authentication system and data encryption techniques to make
the system very secure. For this reason Mifare cards are often used for
financial or ticketing applications where privacy of data and reliable, secure
data transactions are essential.
The higher frequency operation allows communication rates up to 106 kbaud.
Memory is organized as 16-byte Blocks. Groups of 4-Blocks are called Sectors,
each having have unique security keys and access conditions. Block 0 contains a
factory programmed 4-byte unique serial number (UID) together with other
manufacturer and configuration information.
Data can be read/written to Blocks (16 bytes) in one operation. Mifare is
widely accepted as the Market-leading technology for ISO14443A secure ticketing
and access control applications (Transport for London Oyster card for example).

Supported Transponders – Philips Mifare UtralightUltralight has a 256
byte read/write memory without the key code security. All Mifare cards have a
unique serial number factory-programmed at the first location in memory.
13.56 MHz, 512 bit (64 byte) read/write passive RFID transponder.
Ultralight has the same basic communication protocol as Mifare 1k and 4k
cards but does not have the same level of mutual authentication and CRYPTO
protection.
For this reason Ultralight cards are used for simpler financial or ticketing
applications and are often packaged as “paper tickets” for single use
applications.
Memory is organised at 4 byte Pages with Pages 0 and 1 containing a factory
programmed 7-byte unique serial number (UID) together with other manufacturer
and configuration information.
The higher frequency operations allows communication rates up to 106 kbaud
and combined with the flexible memory structure, Mifare Ultralight is a popular
and low-cost read/write transponder type.
Data can be read/written to 4-byte Pages in one operation.
