LDO Unicorn Chasing Kit – Rethonance ADXL

The LDO Unicorn Chasing Kit is a tool for input shaping and mechanical resonance analysis in Klipper. Instead of measuring on the toolhead housing, an ADXL345 accelerometer is integrated directly into the V6-compatible Rethonance measurement nozzle, capturing motion at the nozzle tip itself.

• STM32G0B1-based USB connection to the Klipper host
• Two ADXL/FFC ports
• Four thermistor inputs for motor or chamber temperatures
• Additional SPI and GPIO expansion ports
• Magnetic mounting on the build plate using a printed holder
