There are a few ways to get your hands dirty with MothSynth, build one yourself from modules easily obtainable from Amazon or AliExpress, manufacture your own PCB, or purchase one from our store.

MothOS, the default Arduino compatible software, currently supports 4 tracks, 2 drum machine banks, 10 instrumets and 5 effects (delay, lowpass, phaser, reverb and overdrive), but who knows where developers will take it! Check out our GitHub and Schematics below!

To upload your own samples to MothSynth, clone the GitHub repo, convert your samples with sample converter and replace .h files in the Samples folder of MothOS Arduino Project.


DIY Module List, for this you'll just need to buy the modules from your favourite online retailer, solder them together and modify pin settings in MothOS:

* ESP32 S3 Dev Board MUST HAVE AT LEAST 512kb RAM & 4MB FLASH
* PCM5102A or Max98357 Breakout Board (Use same pins for both)
* Arduino Compatible Keypad
* 4 LEDs + Required Resistors
* 1306 OLED (Optional), use I2C, Modify Pins in MothOS.ino

Important! When compiling the arduino sketch, you must select PARTITION SCHEME / HUGE APP (3mb) from the tools menu, otherwise the app won't fit on your ESP32
