ADSR Module: common questions

What microcontroller does the ADSR Module use?

The ADSR Module is built around the Teensy4.0, from the NXP family.

How big is the ADSR Module?

The ADSR Module measures 53.3 × 106.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ADSR Module?

40 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the ADSR Module design files?

From the Fora888/fully-digital-modular-hardware-synthesizer repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ADSR Module design in my own project?

Yes, under the terms of its MIT license, which Fora888 chose for the repository.

Can I test firmware for the ADSR Module without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
