What
Dreamer and niz are building a Beaks module.
This is a low cost through hole clone of Mutable Instruments Peaks. With the code from Mathias Levy's project $peaks which uses the dual pwm feature of the STM32 and some changes to the code by him. This page outlines the hardware design of a module very similar to the Peaks with the hardware changes by Mathias. Licensed under a cc-by-sa 3.0 license.
