Serial: Full duplex, 8-bit, 38.4Kbaud (default, other baud rates supported via initialization file).

Trigger inputs: Logic level 3.3V–5.0V, active low inputs, w/ internal pull-ups (connector provides individual grounds, allowing switches or jumpers to be connected directly to each trigger input).Audio output: Headphone stereo (1/8” stereo jack).Current Consumption: Approximately 45mA idle, 85mA playing.Input Voltage Range: 4.5V to 12.0V DC, or regulated 3.3V (jumper selectable).Here is a brief overview of the MP3 Trigger's specifications: Specifications You may use headphones, a 3.5mm-to-3.5mm audio cable to connect to an external audio source, or one of our 3.5mm Audio pigtails to wire your MP3 Trigger to the output you desire. Last, you will need something though which to play audio.

If you intend on using your MP3 Trigger with another serial device, you need an FTDI Basic or other serial connection. A simple way to power the MP3 Trigger while you're familiarizing yourself with it is to use a 9V wall adapter. To begin, you'll need an microSD card on which to store your. To get started with your MP3 Trigger, you'll need a few items not included. Using these features, custom applications can often be implemented without the use of a separate microcontroller. In addition, a restart lockout option can be used to prevent any trigger from starting a track if audio is already playing. This version of the MP3 Trigger includes firmware that supports the use of an initialization file on the microSD card that can be used to change the serial baud rate, as well as to repurpose any of the 18 trigger inputs to alternate functions, such as random and sequential triggers, navigation controls and even volume controls. Also, a new trigger filename convention provides greater flexibility in naming your MP3 tracks and makes file management easier. Each conventional trigger can be set to either allow immediate restarts, or to lock out restarts if audio is playing. This version also supports an optional initialization file that can be used to set the serial port baud rate as well as to reprogram any of the 18 trigger inputs to alternate functions, including random and sequential track selection, transport controls and even volume up/down. The heart of the MP3 Trigger board is the Cypress PSoC CY8C29466-24SXI microcontroller which serves up MP3 data to a VLSI VS1063 audio codec IC.
