This is a downstream E-blocks peripheral module, designed to be controlled by one of the upstream E-blocks processing boards which are available in a variety of MCU/FPGA architectures. The DSP Output Board allows the exploration of DSP (Digital Signal Processing) style digitally sampled analog waveforms such as audio or feedback control signals. The board features multiple adjustable amplifier stages, a high-speed 16-bit digital-to-analog converter (DAC), a configurable low-pass filter circuit and multiple test points for an oscilloscope so you can monitor the signals at various stages in the output chain. The board also has an LED output which detects if the signal is being over amplified (and thus indicates potential loss of signal data). Using this board, it should be possible to configure almost any analog representation of the host microcontroller's digital signal so that it can be used in any external circuitry. DSP Output Board Features - On-board 100Ksps 16-bit DAC
- Eight active amplifier circuits
- Configurable active low-pass filter circuit
- Scope test points
- On-board speaker
- On-board mono line-out jack
- Compatible with both 3.3V and 5V upstream E-blocks
The board's patch/jumper system allows you to route the signals to different pins on the downstream E-blocks connector, or to individual female pin headers.

E-blocks Overview E-blocks are small circuit boards each of which contains a block of electronics that you would typically find in an electronic system. Each E-Block performs a separate function as either an input sub-system, an output sub-system, an input/output sub-system or a processing sub-system. E-blocks can be put together to form a variety of systems that can be used for teaching and learning electronics, and for the rapid prototyping of complex electronic systems. Each E-block has one or more 9-way D-type connectors that provide up to eight input/output lines and a ground line. These D-type connectors allow connection between E-blocks to be made in buses of multiples of 8 lines, just like a real electronic system. Power is routed separately to those E-blocks that need it. Processing E-blocks based on PIC, dsPIC, ARM or AVR microcontrollers, Altera FPGAs, Arduino or Raspberry Pi control the whole E-blocks system. Processing E-blocks provide up to five input/output ports with up to eight lines per port. Please see the E-Blocks Category for a list of available components. For more details on E-blocks, see the E-Blocks User Guide (in English, French, German and Spanish) or watch the Introduction to E-Blocks video.
