BMHB2010:BH67F2476 BGM Dev Board Resources
The BMHB2010 is a development board designed for 24-bit A/D glucose meter MCU, the BH67F2476. There are two LCD interfaces to connect to an external LCD module. It’s suitable for developing products such as blood glucose meters, 2-in-1 blood glucose and blood pressure monitors, and hemoglobin testing devices.
BH67F2476 has a built-in phase angle and electrochemical measurement AFE circuit, which can directly measure AC impedance, phase angle, and various electrochemical physiological parameters. It also supports I2C, SPI, and UART communication interfaces.
Quick Start
Version Date: 2026-05-22
The BH67F2476 EVM BGM is a Bio-impedance Analysis (BIA) and Electrochemical Impedance Spectroscopy (EIS) evaluation platform based on Holtek's BH67F2476 SoC. Paired with the EISVision host software, it lets you configure excitation signals, perform impedance frequency sweeps, and validate body-composition algorithms at the board level. This resource set provides the quick-start guide, chip datasheets, EVM schematic and PCB design pack, driver source code, and host software. The complete resource package contains the documents, hardware design pack, and driver source; the host software is provided as a separate Software download.

- Read the docs — read this README to understand the resource layout, board design pack, driver source, and host software
- Prepare the hardware — get an EVM BGM board (V2.0 design in
3.board/), then confirm power, interfaces, and jumpers from the board design files and board silkscreen - Connect the host — install and launch
4.AP/EISVision.exe, connect to the EVM's serial port - Driver source — build and flash target firmware from
2.code/bh67f2476_driver/(HT-IDE) - Run an EIS / BIA experiment — configure excitation frequency and current from EISVision, capture impedance data
- Customisation — adapt the projects under
application/andexample/for your own product
