Pi Pico Oscilloscope Kit
Build a Credit-Card-Sized 500kHz Oscilloscope with Raspberry Pi Pico
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Capture and analyze real-world signals at half a million samples per second-without a bulky benchtop instrument. This Raspberry Pi Pico-powered oscilloscope fits in your pocket yet displays crisp waveforms with independent trigger and timebase controls on a bright 0.96-inch OLED. Two smooth potentiometers let you dial in the trigger threshold and sweep speed while tactile buttons switch capture modes, all sealed inside a sturdy ABS enclosure barely larger than a credit card.
What You'll Build
A battery-operated, portable oscilloscope that visualizes voltage signals up to 500?kHz on its 128�64-pixel OLED. The timebase is adjustable from 50?�s/div down to 50?ms/div, and a configurable trigger level locks noisy signals into a stable display. You will solder the entire signal chain-from the LM358 buffer and level-shifter through the Pico's ADC to the I2C OLED-and load the firmware that turns a microcontroller board into a real measurement tool. The final device is a self-contained diagnostic companion ideal for checking sensor outputs, audio waveforms, and PWM duty cycles on the go.
What You'll Learn
- Configuring the Raspberry Pi Pico's ADC for high-speed sampling at 500?ksps using DMA and PIO
- Displaying real-time waveforms on an I2C OLED with a custom plotting routine optimized for 128-sample frames
- Implementing trigger logic with a potentiometer-controlled threshold and the LM358 as a comparator
- Designing a physical user interface that blends two pots and two tactile buttons to adjust timebase, holdoff, and mode

Who This Kit Is For
CBSE Class 11-12 students exploring waveforms in physics or electronics lab will find this kit a tangible intro to signal acquisition. B.Tech ECE and EEE students can use the finished scope as a portable benchtop tool for mini-projects and lab work. Smart India Hackathon teams and ATL Tinkering Labs that need a compact measurement device for embedded prototypes will appreciate the credit-card footprint and battery-powered independence. IIT, NIT, VIT, and BITS students looking for a hands-on soldering and coding challenge will also enjoy building a tool they can carry everywhere.
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?
The AI companion, triggered by the QR code on the box, guides you step by step with wiring diagrams and code. If a human touch is needed, message us on WhatsApp-our build team responds within hours.
What maximum frequency can I measure with this oscilloscope?
The Pi Pico's ADC samples at 500?kHz, so according to the Nyquist theorem you can reliably view signals up to 250?kHz. For repetitive waveforms the scope will display up to 500?kHz, though the display refresh rate will limit real-time viewing.
Can I power it from USB instead of the 9V battery?
Yes, the Pi Pico can be powered through its micro-USB port, which also provides the 5?V rail needed by the OLED and LM358. The battery snap is included for truly portable use, but USB power works perfectly during bench debugging.
Is any soldering experience required?
You will solder through-hole components onto the provided prototyping boards, so basic soldering skills are assumed. The AI companion includes a soldering refresher guide and safety tips if you need a quick start.
