⚡ Picotronix: modular scope with two Pico 2 boards

Picotronix is a modular oscilloscope, logic analyzer, and frequency meter currently in crowdfunding. Developed by Sydney-based Thort Werx Pty Ltd, the device utilizes two Raspberry Pi Pico 2 microcontrollers to handle signal processing and connectivity tasks.

The architecture separates functions between two specific boards. A standard Raspberry Pi Pico 2 acts as the signal processor, while a Raspberry Pi Pico 2 W drives the display and provides wireless connectivity. This dual-board approach allows for distinct handling of analog data and user interface operations.

The core unit, named the Picotronix Main Module, features an integrated 320 × 240 color LCD from Pimoroni. It includes three expansion ports designed to accept picoPods plug-in modules. These add-ons enable high-speed ADCs, mixed-logic family logic state analysis, waveform generation, and analog conditioning.

Key specifications include a two-channel digital storage oscilloscope and an 8-channel logic analyzer. The logic analyzer can expand up to 14 channels with a picoPod. The system supports a sample rate of up to 150 MHz. Analog channels accept 3 Vpp or 16.6 Vpp at 1 MΩ.
