Logic Analyzer Rig — ESP32 8-Channel Sniffer

Description

See what your circuit is actually saying. An 8-channel, 24MHz logic analyzer paired with a pre-flashed ESP32-C3 captures I2C, SPI, UART and 1-Wire traffic and streams decoded frames to a web UI over Wi-Fi — no USB tether, no desktop software required.

What is in the box

• ESP32-C3 SuperMini development board (pre-flashed with the sniffer firmware)
• 8-channel 24MHz logic analyzer module
• 10 test hook clips + dupont cable set
• USB-C cable
• Step-by-step build guide

Clip the hooks on any bus, power up, open the web UI: channels, triggers and protocol decode are all live. Full wiring pin map is in the guide. Flash your own firmware later — the rig is a standard ESP32.
