Note: It is recommended to order the latest version, 1.2.2. If you need, please go to WULPUS Acquisition PCB v1.2.2.

This PCBWAY project replicates an Acquisition PCB for the WULPUS platform.

WULPUS is an open-source compact, ultra-low-power research ultrasound platform designed for wearable applications. It features + 15 V unipolar programmable excitations, 8 time-multiplexed channels, an 8 Msps 12-bit ADC, and a 40.8 dB gain amplifier, ensuring high-quality signal processing. With BLE connectivity (320 kbps) and a power consumption of just <25 mW, it enables real-time, wireless multi-day continuous ultrasound monitoring powered from a single battery.

The system consists of two PCBs: an Acquisition PCB, housing the MSP430FR5043 ultrasound MCU and nRF52832 BLE MCU, and a High-Voltage PCB with a HV multiplexer, TX/RX switch, and MOSFET driver. This design allows for efficient ultrasound signal acquisition, processing, and wireless transmission.

With its 46 × 25 mm footprint and 9 g weight, WULPUS offers up to 50 acquisitions per second (400 samples per acquisition), making it ideal for wearable ultrasound applications requiring continuous monitoring and mobility.
