A collection of compact, power-efficient PCB modules designed for rapid prototyping and development of wearable healthcare devices, with a focus on biosignal acquisition.
X-MODs provides a modular hardware approach that bridges the gap between fully custom designs and off-the-shelf solutions. The system consists of four specialized modules and their corresponding debug boards, enabling quick prototyping while maintaining the small form factor required for wearable applications.
- Built around the HEEPocrates RISC-V SoC
- Multiple communication interfaces (UART, I2C, SPI)
- High-efficiency PMIC
- 5 independent voltage rails
- LiPo battery charging capability
- Integrated coulomb counter for accurate battery monitoring
- 16-bit precision
- 4 multiplexed input channels
- 1 MSPS sampling rate
- Optimized for biosignal acquisition
- Dual NOR flash configuration
- Expandable storage capacity
- Pin-compatible with various memory sizes
- Designed for autonomous data acquisition
Each module comes with a companion scoket board featuring:
- Spring-loaded pogo pins for solderless connections
- Easy module swapping capabilities
- Breadboard-compatible format
- Testing and validation infrastructure
These modules are particularly suited for:
- EEG signal acquisition
- Wearable medical devices
- Clinical trial prototypes
- Academic research projects
- Low-power embedded systems
