500DPI Optical Fingerprint Module UART USB SPI | JP300
Asia-Teco JP300 500DPI Optical Fingerprint Module
The Asia-Teco JP300B is a compact, high-performance optical fingerprint module combining a 500DPI CMOS fingerprint sensor with an integrated single-chip fingerprint processor. Designed for seamless secondary development and embedded system integration, this module delivers fast, accurate fingerprint enrollment, verification, and identification — all in a low-power, small-form-factor package. Made in Mainland China.
Why Choose the JP300 Fingerprint Module?
- All-in-One Design: Integrates fingerprint acquisition and processing into a single chip, simplifying your hardware design.
- Triple Interface Support: Communicates via USB 2.0, UART (3.3V TTL logic), and SPI — flexible enough for virtually any embedded or PC-based project.
- High Accuracy: False Acceptance Rate (FAR) <0.001% and False Rejection Rate (FRR) <0.1% at Security Level 3, with 5 configurable security levels.
- Self-Learning Algorithm: After each successful match, the module updates its fingerprint database with the latest feature values for increasingly accurate recognition over time.
- 360° Random Recognition: Reads fingerprints at any orientation for effortless, natural use.
- Ultra-Low Power Consumption: Only 40mA during active operation; drops to just 2µA in sleep mode — ideal for battery-powered applications.
- Fast Identification: Identifies from a database of 3,000 fingerprints in under 1.5 seconds.
- Finger-Sensing Wake-Up: The Wakeup pin goes HIGH when a finger is detected, enabling efficient power management.
- Infrared Anti-Glare & Anti-Static: Leaves no residual fingerprint image on the sensor surface; built to 30kV anti-static standards.
- Broad OS Compatibility: Works with Windows (98/Me/XP/2000/2003/7/8/10) and Android 4.0+, as well as microcontroller environments.

Frequently Asked Questions
Q: What communication interfaces does the JP300 fingerprint module support?
A: The JP300B supports three communication interfaces: USB 2.0, UART (3.3V TTL logic), and SPI. This makes it highly versatile and compatible with a wide range of microcontrollers, single-board computers, and PC-based development environments.
Q: How many fingerprints can the JP300 store and how fast does it identify them?
A: The JP300B can manage a large-capacity fingerprint database and performs 1:N identification of 3,000 fingerprints in under 1.5 seconds, making it suitable for both small embedded projects and medium-scale access control applications.
Q: Is the fingerprint module compatible with Arduino or Raspberry Pi?
A: Yes. The JP300B operates via UART and SPI interfaces at 3.3V TTL logic levels, making it straightforward to integrate with Arduino, Raspberry Pi, STM32, ESP32, and most other popular microcontroller platforms. It also supports Windows and Android operating systems for PC-side development.
Q: What security level should I configure for general use?
A: The module ships with Security Level 3 as the default, which balances accuracy and usability with a False Acceptance Rate below 0.001% and a False Rejection Rate below 0.1%. Security can be adjusted between Levels 1–5 depending on the sensitivity of your application.
