Research Lab Kit 19 High Speed Data Acquisition
Capture and Stream Fast Transient Signals with ADS8688 & STM32 Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit puts a 500-ksps, 16-bit data acquisition system on your bench. You will build the entire signal chain—from SMA‑connected analog input to live numeric stream on your PC—using the ADS8688 precision ADC and an STM32 Nucleo. It is purpose‑built for capturing fast voltage edges, sensor pulse responses, and other transient events that ordinary microcontroller ADCs miss.
What You'll Build
You will assemble a working USB‑CDC data acquisition tool that digitizes analog signals at up to 500,000 samples per second. Two SMA connectors accept standard BNC probes, and the STM32 firmware pushes every sample to your computer in real time. Once completed, you can view raw waveforms in a serial terminal or run the included Python script for live plotting and analysis.
What You'll Learn
- Configure the ADS8688 16‑bit ADC over SPI for 500 ksps continuous conversion
- Write STM32 firmware with precise timer‑driven sampling and double‑buffered data transfer
- Implement USB CDC (virtual COM port) to stream high‑speed data without custom drivers
- Capture and visualise real transient events—switch bounce, sensor pulses, or oscillator output—on a PC in milliseconds

Who This Kit Is For
B.Tech ECE/EEE students building final‑year projects on real‑time data capture, M.Tech researchers who need a transient recorder for sensor characterisation, and Smart India Hackathon teams requiring a reliable analog front‑end. It fits advanced lab classrooms at IIT, NIT, VIT, BITS, and engineering colleges where students move beyond Arduino and into professional‑grade instrumentation.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Open the AI build companion on your phone using the QR code. It walks you through every wiring step and firmware configuration. If you need a human, reach out via WhatsApp—we respond within hours.
What sampling rate can I really achieve?
The kit reliably streams 500 ksps over USB CDC when built as instructed. The STM32 firmware uses a hardware timer and DMA to keep timing tight; you will see the full 500 000 samples per second in your terminal or Python script.
Can I connect my own BNC probe or sensor?
Yes. The two SMA connectors accept the included BNC cables, which connect directly to standard oscilloscope probes, function generators, or any BNC‑terminated sensor you already own.
How do I view the data on my PC?
The kit acts as a virtual COM port. Any serial terminal (PuTTY, minicom) will display the raw hex or decimal values. For real‑time graphs, use the provided Python script that plots samples as they arrive—no extra hardware needed.
