UHF RFID Module VM-M18

-Thoroughly solve the problem of overheating:
1. No external heat dissipation device is required. Long term continuous full load operation at room temperature without generating heat.
2. Continuous current<200mA @ 3.5V (26 dBm Output). Peak pulse current<260mA.

-Excellent stability:
1. 24 hours x 365 days of work without crashing.
2. The performance is less affected by external factors such as the casing and electromagnetic environment.
3. Wide temperature design with extremely low temperature drift coefficient.

-Excellent consistency:
1. A masterpiece of consistent design.
2. All use the highest grade components to ensure stable and consistent parameters.

-Concise and efficient software and hardware interfaces:
1. The peripheral circuit is extremely simple, with a single power supply and no need for external tantalum capacitors.

-Installation method: Post weld pins.
