Frequently Asked Questions

What is the primary function of the Grow KS220-L board?

The KS220-L is a dedicated fingerprint processing control board. It handles fingerprint image capture from a connected sensor module, performs template extraction and matching using an onboard algorithm, and communicates the result via a simple UART serial interface, freeing the main host microcontroller from complex biometric processing tasks.

What communication interface does this board use to connect to a microcontroller?

The board uses a standard UART TTL serial interface (TX, RX, GND, VCC). It is compatible with both 3.3V and 5V logic levels, allowing for direct connection to popular platforms like Arduino, ESP32, STM32, and Raspberry Pi without the need for level shifters.

Does this board include a physical fingerprint sensor?

No, the Grow KS220-L is a control board only. It requires an external optical or capacitive fingerprint sensor module (typically connected via a specific serial protocol) to capture the fingerprint image. The board then processes the image data received from that sensor.
