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
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 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.
