The $5 Tool You Didn't Know You Needed (Win/Linux/Mac & Demo)

In this video, we take a close look at the popular and inexpensive 24 MHz 8-channel USB logic analyzer. We tear down the hardware to see how the onboard Corebai CBM9002A MCU and EEPROM handle firmware loading, set it up across Linux, Windows 11, and macOS, and demonstrate real-world signal analysis by capturing and decoding data from an AM2302 (DHT22) sensor.
