what is the max current in ma this device can supply?

ifyou have something that requires more than a single LED you'll have to provide that power via something else, this can't provide any useful power to anything, it's only there to make sure you'll have the same voltage level as the chip is working with, that's selectable by the jumper and you can choose 3.3 volt or 5 volt but these voltages are solely for setting the communication voltage for the communication lines, that's it so do not use it to provide any significant power to your project, you'll destroy it.

can i switch between 5v and 3v data rate?

3V3 and 5V are selected by short circuit, and the short circuit voltage is selected on the 6PIN pin header. (Front view, count from top to bottom) 1, 2 short circuit is 5V TTL output, 2, 3 short circuit is 3V3 TTL output; ... see more see less

Product Safety Information

Setup Guide

Identify the pins

Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.

Wire to your microcontroller

Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.

Install libraries

In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.

Upload example sketch

Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.

Calibrate if needed

Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
