3.12 Inch Monochrome Oled display module (Yellow) 12 Volt 2 Amp Power Adapter AC to DC Initialize serial communication at 9600

Initialize serial communication at 9600 baud rate and send AT commands to test network registration: AT (should return OK)

sending AT+NAME=MyDevice will rename the Bluetooth device

The module communicates with your host system via SPI (Serial Peripheral Interface)

ensuring frequency-critical RF circuits maintain calibration across -55°C to +125°C operating range
