NRF-TXT T114 Buzzer

The nRF52 board’s GPIO pins can only supply up to 15mA, which isn’t enough to drive a buzzer properly—resulting in a very quiet sound. These Passive buzzers include a built-in NPN transistor, allowing them to draw power directly from the battery while still being controlled by the GPIO pin. This setup lets Meshtastic trigger the buzzer while delivering a much louder and more reliable alert.
