Application note:
The peak current can reach over 500mA. Please make sure you have a capable and stable power supply available. You will not be able to power this module from the 3.3V output of an Arduino board or a USB-UART like FT232 or CH340. A larger electrolytic capacitor (e.g. 1000µF) close to the power pins is highly recommended.
