Out of stock


H26R00 is a load cell (strain gauge) sensor interface module based on Avia Semiconductor HX711 Wheatstone bridge ADC and STM32F0 MCU. This module is a precision 24-bit analog-to-digital converter (ADC) designed for weigh scales and industrial control applications. It interfaces to load cells (strain gauges) in a Wheatstone bridge configuration. The module accepts a full bridge (5-pin connection) as well as a secondary sensor connection (2 pins).

  • Use this module to build digital scales for home, commercial and industrial applications.
  • Combine with other Hexabitz hardware to add industrial I/Os or communication capabilities (RS485, Ethernet, CAN, BLE) to your industrial and commercial weight scales.
  • Program advanced C code using our easy-to-use APIs and messaging system.
  • Connect to external hardware or combine with other Hexabitz modules!



  • Avia Semiconductor HX711 24-Bit Analog-to-Digital Converter (ADC) for Weigh Scales:
    • 24-bit precision with two selectable differential input channels.
    • Low noise PGA with selectable gain of 32, 64 and 128.
    • Output data rate of 10 or 80 sample/sec.
  • Wheatstone bridge voltage of 2.5V.
  • 5-pin and 2-pin Phoenix 3.5mm terminal connectors for a full Wheatstone bridge and a secondary bridge.


  • STM32F091CBU6 32-bit ARM Cortex-M0 MCU.
  • 8MHz external oscillator.
  • Five array ports and four power ports (+3.3V and GND).
  • Access to 5xUART, 1xI2C, SWD, BOOT0, RESET.
