is a device; applying 5V directly to the VCC or logic pins without a level shifter can damage the module.

is a highly versatile, low-cost 2.4GHz wireless serial port module. Unlike Bluetooth, it uses a proprietary 2.4G protocol, making it faster for simple point-to-point communication between Arduinos with a range of up to 120 meters. Key Technical Specs Operating Voltage : 2.2V - 3.6V (Use a 3.3V regulator; it is 5V tolerant on VCC). : Standard Serial (UART). jdy40 arduino example best
