Description
TeknoCrafters FA3021 650nm 5V Laser Transmitter Sensor Module (KY-008 Class)
The TeknoCrafters FA3021 is a compact and efficient laser transmitter sensor module, modeled after the KY-008 platform. It features a 650nm red laser diode that emits a focused dot, making it ideal for applications requiring precise laser targeting or signaling. This module is compatible with microcontrollers such as Arduino, ESP32, and ESP8266. For Raspberry Pi users, an external analog-to-digital converter (ADC) is necessary due to the lack of native analog input.
