Base is an open source PCB design by bread-modular: a 2-layer, 223.5 × 160 mm board with 163 components (38 distinct parts). It is built around the MCP6002T-I/SN, AP2112K-3.3TRG1, TPS2111APWR. Filed under audio.

Modular Synths for Everyone

Modular Design: Just like Eurorack USB-Powered: It can be portable Minimal Design: Cost Effective Modular MIDI Support: Use MIDI to communicate between modules (still supports CV & Gate) Analog and Digital Signal Paths: It’s your choice Diverse Built-in Modules: Includes a wide range of pre-designed modules Configurable Digital Modules: Supports both voice and CV (uses AtTiny 1616 or ESP32) Fully Open Source: Including schematics, PCB designs, and code Ease of Customization: Enables straightforward creation of custom modules tailored to specific needs. No Case Required: Can be used directly…
