ELEGOO Strain Gauge Adapter Board for Centauri Carbon

The board that sits between the bed strain gauges and the Centauri Carbon mainboard. It carries four 24-bit HX711 ADCs — one per sensor — and its own microcontroller, so the mainboard receives finished numbers rather than raw analog. That's what keeps the tiny sensor signal from drowning in stepper noise and makes auto bed leveling fast and repeatable.

Specifications

• Four 24-bit HX711 ADCs, one channel per strain gauge
• Onboard STM32 microcontroller, serial link to the mainboard
• Four sensor headers plus a 24 V supply input
• Mounts in the stock position, connectors only — no soldering

Compatibility: ELEGOO Centauri Carbon. Third-party sellers list the same board for the Centauri Carbon 2 as well, so check the listing description against your model.
