About this product

TFA1500-L is a lightweight 905 nm rangefinder module for mini drones, gimbals and other host-integrated ranging devices. The PDF lists a 0.5–1500 m range under specified visibility, humidity and target-size conditions, an adaptive 60–800 Hz mode and 3–5 V supply. The current product page additionally describes a 1–4 Hz low-frequency mode and a 1300 m high-frequency range. Published power limits and pin-4 assignments differ between the PDF and current page, so their claims are kept separately pending hardware/firmware confirmation.
