The Full system
RFID Reader ID-12
Features:
- 5V supply
- 125kHz read frequency
- EM2400 64-bit RFID tag compatible
- 9600bps TTL and RS232 output
- Magnetic stripe emulation output
- 100mm read range.
VDIP USB Host Controller
Description:
The VDIP1 module is an MCU to embedded USB host controller development module for the VNC1L IC device.
Features:
- Single 5V supply input from USB connection.
- Built-in 8/32 bit MCU.
- Handles the FAT file structure via a simple command set.
- Program or update firmware for data transfer function.
- Low power operation (25µA at running,2µA at stand By).
- Description
- primary memory which size is 64kbit, using I2C protocol Interface.
- Number of student can be saved in it :
- 64kbit8=8kbyte
- Every student is represented by 9 bytes
- ( 8*1024)=81929= 910 students.
Real Time Clock DS1302
- Backup battery with 9 years life time.
- Uses I2C protocol interface.
