Open modular audio platform for musicians, engineers, and developers.
T-DSP combines studio-quality audio with the Teensy microcontroller and the Teensy Audio Library in a flexible, hackable format. Build custom digital mixers, craft unique instruments, prototype audio products, or just experiment with DSP -- T-DSP gives you the tools to bring your ideas to life.
Desktop audio backplane hosting Teensy 4.1, ESP32, and TAC5212 codec with USB Audio, MIDI, and S/PDIF. 8-layer stackup for maximum analog/digital isolation.
4-layer digital backplane hosting Teensy 4.1 and ESP32. USB Audio, MIDI, Ethernet, and TDM expansion headers for connecting T-DSP audio modules.
Compact stereo audio codec module built around the TI TAC5212 -- the core building block of the platform.
2-in / 2-out balanced audio I/O backplane with combo (XLR/TRS) inputs and XLR outputs.
Compact carrier board that connects a TAC5212 audio module and Teensy 4.1 into a USB-powered audio shield with stereo line I/O, PDM MEMS mics, and USB Host.
- Modular -- Codec modules solder onto backplane PCBs like components. Design your own backplane with whatever jacks and connectors your application needs.
- Open hardware -- All designs are KiCad projects with schematics, PCB layouts, BOMs, and 3D models published here.
- Standard interfaces -- I2S audio, I2C control, 2.54mm headers. Works with Teensy, ESP32, or any compatible microcontroller.
Browse the repositories to explore the hardware designs. Each project includes online viewers, interactive BOMs, and documentation.
