Work in Progress
Manifold Spycable is a project that aims to explore the boundaries of miniaturized embedded electronics by integrating a fully functional computer within a standard XLR connector.
The Manifold Spycable comprises several components:
- A single PCB computer designed to fit inside a standard XLR connector (such as the Neutrik NC3MMX or similar) - similar form factor as Manifold PAT-MAT
- Powered directly from standard 48V phantom power, commonly used in professional audio equipment.
- Equipped with:
- TI PCM1820/1821/1822 ADC for audio data conversion.
- ESP8685 MCU based on the RISC-V ESP32-C3 core with Wi-Fi capability.
- Features a u.FL IPEX connector for a Wi-Fi antenna. A detailed evaluation of compatible antennas (e.g., Fractus Compact Reach Xtend with coax cable) will be added later.
- Designed to allow space for a microphone cable to pass through, enabling the creation of standard-looking XLR cables capable of audio data transmission and recording.
Custom firmware for the ESP8685 to handle audio data acquisition from the ADC and real-time data transmission over Wi-Fi.
Software for standaerd computer systems to process the incoming audio data streams. Possible functions might include audio file recording and real-time playback.
This project is in its early development stage. Currently, only the hardware design for the device is ready. Firmware and receiver software development are still in progress.
Note: This project may have potential data security implications if used in unintended ways. However, it is intended purely for educational, experimental, and demonstration purposes.

Stay tuned for:
- Firmware updates for the embedded ESP8685.
- Antenna recommendations and performance benchmarks.
- Receiver software to enable audio recording and playback.
