The BH66F2660 is a Holtek 8-bit body fat measurement Flash MCU which includes a multi-channel 24-bit Delta Sigma A/D converter, PGA and LDO and other circuitry specifically designed for Body Fat Scale applications.

The BH66F2660 supports both weight and AC body fat measurements (compares with traditional DC fat scales, the AC has a better accuracy). The measurement data can be transmitted by the internal SPI / I²C / UART serial interfaces and an external RF module, and displayed on a mobile phone. The data can also be transmitted by the internal LED driver and displayed on an LED panel.
