Two goodies from NOISIO!
You can buy both kits in a bundle for 80.-€. Enjoy soldering!
ATBase Console
Expandable ATtiny85 synthesizer, which acts as a basis for a mini modular setup.
The ATBase is the next level ATtiny Punk Console with an extended frequency spectrum into the bass range. Three red 3.5mm jacks now replace the body contacts. These can be used to manipulate parameters from the outside with control voltages of 0-5V. The trick with the red marked jacks is to lead out the supply voltage and simultaneously lead back the modulation signal via a stereo cable. This allows you to test your own CV circuits (e.g. super simple with 2 components: a resistor + light sensor) or connect noisio CV modules.

LFO/EG
Maybe the smallest LFO (Low Frequency Generator) and envelope generator module (ADSR) in one. 68mm x 45mm, 5V-level. Powered by ATBase or to use standalone with USB to stereo mini jack adapter.
The LFO/EG can be operated as a 5 volt low frequency oscillator or envelope generator. You can set the mode by pressing the button at startup. In LFO-mode 5 waveforms are available: Square, Sine, Triangle, Ramp-Up, Ramp-Down. Furthermore, speed, modulation depth and bias (average value) can be set. As an envelope generator, the module can process the classic parameters attack, decay, sustain and release. The signal can be triggered via the gate input or the button. The LFO/EG can either be connected directly to the ATBase via the red jack or can be used standalone with any CV capable device and a USB to mini jack adapter.
