The Fingerprint Sensor with Two-Color LED Ring (GROW R503) is a capacitive fingerprint sensor module scanner with a two-color ring indicator from Hangzhou Grow Technology Co., Ltd. designed with the intention to be used as an extension of development boards and placed remotely on Fingerprint 3 Click. The module is designed in a circular shape with a diameter of 28mm. It's important to mention that this module represents an integrated image collecting and algorithm chip together.
