The BMHB1005 is a development board for Holtek BH66F2662 / BH66F2652 Body Fat Measurement Flash MCU. It is designed and produced by Best Health Electronics Inc.
The BH66F2662 / BH66F2652 includes a fully integrated body fat measurement circuit, a 24-bit Delta Sigma A/D converter, LED driver, and UART / SPI communication interfaces, making the devices suitable for use in various four-electrode LED Bluetooth AC body fat scale related products.
The device’s internal integrated four-electrode AC body fat circuit which uses AC body fat measurement technology can implement more accurate impedance measurement and also greatly reduce the external component requirements, such as amplifier, analog switches, and sine wave generator. This results in major reductions in manufacturing and component costs as well as improved productivity. The internal 24-bit Delta Sigma A/D Converter together with the internal LDO can provide power to external sensors for weight measurement purposes.
