Introduction

The Nano DSP is a flexibeel audio DSP Module with 2 inputs and 4 outputs. By adding to a wide range of connectors, the NanoDSP is ideally suited to be used for, for example, 2 Input 4 Output signal processing or Mono processing, Balanced in Processing or more. Output can be configured as 4 unbalanced or 2 balanced Outputs. All boards have been tested manually and contain a test program that is set to 2 channels as 3KHz output.

Connectors

The module is supplied WITHOUT connectors for making sending extra easy. However, the NanoDSP requires a minimum of 10 pin boxed header for programming and a 2 pin screw terminal for feeding the board. The pitch of the boxed header is a double 5 pin row with a 0.1 "pitch. The power connector is a standard 0.2" pitch connector. There is also an unused header for future purposes, this is between the power connector and the programming connector

LED drive

A standard Bi-Color LED common cathode is positioned next to the potentiometer and can be used as a signal indicator or overload indicator. The LED is controlled by the DSP from GPIO_4 and GPIO_5. The LEDs both have a Pfet Buffer, so if you want to activate the LED you will have to make the Line "Low". In the DSP hardware register configuration, it is easy to change the polarity so that the LED is activated when the signal is "high".
