Product Name: Arduino uhf rfid module with TTL interface
Item Code: VM-5GA
Category: Access Control Card Reader Add to Favorite Categories
Short Description: 40*40 mm, 902- 928/865-868Mhz, CE, 2-3m read disance, TTL interface, 1 set RFID reader module with 1 ceramic antenna integrated,1x SDK pack
Quantity: 1 Piece
Gross Weight/Package: 0.02( kg )
Ø Integrated antenna character
1. Be sensitive and stable to the tags identify.
2. Stable reading distance 2-3 meters.
3. Multi-tags identify, >50pcs tags.
4. Reading distance speed, >50pcs/sec.
Ø Solve the exothermic problem completely.
1. No need for connecting any other outer radiating device. It can work without exothermic reaction in the normal indoor temperature.
2. Sustain electricity<200mA @ 3.5V (26dBm Output). Pulse peak current<260mA.
Ø Outstanding stability:
1. 24 hours x 365days work normally.
2. Appearance little influenced by cover, electromagnetic environment etc.
3. Wide temperature design and the temperature drift coefficient.
Ø Good consistency:
1. the good design in consistency.
2. Choose the top level components to keep each parameters stable and consistence.
Ø Brief and high efficient interface of hardware and software:
1. Peripheral circuit is very easy. The signal power, no need for extra connecting tantalum capacitor.
Installation method: support 5pin WAFER installation
