M5Stack U161 Datalogging and Acquisition Unit features an ExtEncoder, an acquisition unit for an external rotary encoder. This ExtEncode supports AB/ABZ signal input using decoding firmware and STM32F030 central control integrated encoder signal acquisition. The encoded value is directly obtained through the I2C reading operation, like automatic cutting in industrial automation and robot arm position control. This U161 data logging and acquisition unit features AB/ABZ signal input. The U161 datalogging and acquisition kit includes 1x ExtEncoder unit and 1x Grove cable (20cm). This data logging and acquisition unit is ideally used in meter counting applications, encoders, and automated cutting.
