The Fingerprint Recognition Module with Capacitive Sensor is powered by STM32F105 CPU and features a Semiconductor (capacitive) sensor with a module dimension of 45 x 30 mm and a sensor dimension of 33.4 x 20.4 mm. The module has an image DPI of 508 and an image resolution of 192 x 256. The sensing area of the module is 9.6 x 12.8 mm. The module has a fingerprint capacity of 1000 (expandable) and a security level of 0-9, with 5 being the default. The matching time of the module is 1 second, and the false acceptance rate is 0.00%, while the false rejection rate is 0.01%. The module has dynamic current of <40mA and operates at a voltage of 3.3V-5V. The module supports dual communication through UART or USB and has anti-electrostatic aerial discharge of 15KV and contact discharge of 8KV.

FAQs:
Q: What is the maximum number of fingerprints that the Waveshare Capacitive Fingerprint Reader can store?
A: The fingerprint reader can store up to 1000 fingerprints, which can be expanded if needed.
Q: What communication interfaces does the fingerprint reader support?
A: The fingerprint reader supports dual communication through both UART and USB interfaces.
Q: What is the accuracy and speed of fingerprint matching?
A: The fingerprint reader has a matching time of 1 second with a false acceptance rate of 0.00% and a false rejection rate of 0.01%.
Q: What is the power consumption of the fingerprint reader?
A: The dynamic current consumption of the fingerprint reader is less than 40mA. It also has a sleep mode to reduce power consumption when not in use.
Q: What software and resources are available for developing applications with the fingerprint reader?
A: Waveshare provides rich resources for development, including PC software, SDK, tools, and examples for Raspberry Pi, Arduino, and STM32.
