LogicAnalyzer: a Raspberry Pi Pico-based 24 channel logic analyzer
Agustín Gimenez Bernad leads development of LogicAnalyzer, an inexpensive 24 channel logic analyzer with 100Msps, 32k samples deep, edge triggers and pattern triggers.
LogicAnalyzer is a very cheap analyzer based on a Raspberry Pico (or Pico W). The analyzer offers up to 24 digital channels, pre and post trigger sampling, edge trigger and pattern trigger up to 16 bits.
Additionally to the hardware the logic analyzer also includes a powerful software (Windows only for now) where you can visualize the captured data, export captures, use protocol analyzers, etc.
The latest version (5.0) adds Burst mode. With burst mode you can capture blocks of data and the analyzer will rearm itself immediately and capture more data when the trigger condition is met again.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

Can this be overclocked to double original frequency then do 200 MSps?
