Hw-133-v1.0 Datasheet 'link' Jun 2026

The module is a "go-to" for makers because it handles variable input sources (like 7.4V or 12V batteries) and converts them into a stable 5V or 3.3V supply for microcontrollers. It is frequently found in: Aviation Models : Used where weight is a critical factor. Environmental Monitoring Nodes

I’ve got a board marked "HW-133-v1.0" and I’m trying to find a proper datasheet. I think it’s a PIR motion sensor module (similar to HC-SR501), but the pinout and jumper settings seem a bit different. The module is a "go-to" for makers because

The Hw-133-v1.0 is a versatile component with a wide range of applications across various industries, including: I think it’s a PIR motion sensor module
