MINI DSP EVM KIT is an evaluation board for MINI DSP BOARD. With this board it’s possible for the customer test and evaluate all the functionality of MINI DSP Family. The MINI DSP EVM KIT have a MINI DSP BURNER integrated for program the MINI DSP BOARD, so the customer only have to plug and play the system. For customers that want to meet MINI DSP FAMILY, this board it’s the perfect solution. The MINI DSP EVM acts like a little 2x4 audio processor without balanced audio in/out. With this board Is possible to test all the filters, crossovers, dynamics, LED’s and more capabilities of the MINI DSP board.

For MINI DSP EVM KIT, Waveland Team have designed a layout with 2 audio inputs and 4 audio outputs, with input mixer-matrix, and full EQ and dynamics processing in every channel. GPIO port can be used for developer for test external peripheral controls like potentiometers on GPI 3 and 6. For use the system, connect the board to a computer trough Ethernet, open the Waveland Designer Layout and play. Connect audio inputs and outputs and start to sound. For all details of audio processing, or DSP features, have a look to MINI DSP Application Manual.

For GPIO output high

Output levels are 3V3 and 20mA compliant. For connect LEDs, put anode on GPIO output and cathode to GND. We recommend to put a resistor in series with the led to control the maximum current. To test the LEDs push the virtual buttons on the Waveland Designer layout to turn on/off the LED’s. Signal an CLIP LED’s are fixed by Waveland, the customer only can select which channel manage the LED’s. It can be selected between CH1, CH2 or higher level, in Waveland Designer Layout. If another devices wants to be managed with output GPIO, we recommend to use MOSFET transistors in order to isolate output GPIO pins and more current can be managed, depending on transistor used. For example, for manage relays.

For ADC input

For ADC is necessary to adapt input level to avoid full scale saturation before the maximum range of the potentiometer. To adapt 3V3 level to 3V, we recommend to use a simple voltage divider. 10K, 20K or 50K potentiometers can be used, and it’s important to use linear potentiometers to use better all of the potentiometer range. Linear faders can be used too, same as a rotary potentiometer. For using potentiometers is necessary to activate potentiometer input on Waveland Designer layout.

For GPIO input

For GPIO inputs, is necessary to put a pull down resistor to stabilize the logic state at non pushing situations. When a GPIO is pushed a virtual led will blink on Waveland designer layout. If an external device like a MCU want to be used to pull up/down a GPIO input, is very important to check the logic level values to avoid electrical damages in MIDI DSP Board. The maximum input level to GPIO inputs is 3V3.


For using the MINI DSP EVM is necessary to connect a MINI DSP board. This process is very easy, and only consists in plugging the MINI DSP board over the MINI DSP EVM KIT. MINI DSP EVM is ready to work with MINI DSP board, only plugging both boards and starts to play.
