BMHB2019:BH67F2493 BGM Dev Board Resources
The BMHB2019 is a development board for the MCU BH67F2493, allowing you to evaluate the features of this MCU. The BH67F2493 is suitable for applications such as blood glucose meters, 2-in-1 blood glucose and blood pressure monitors, hemoglobin testers, and other products.
Quick Start
Platform: BH67F2493 (8-bit Flash MCU + 24-bit Delta-Sigma ADC + AFE analog front-end) Dev Board Model: BMHB2019 Version Date: 2026-06-01
The BH67F2493 EVM is a multi-function evaluation board for blood-glucose sensing applications. Built around the BH67F2493 body-composition measurement MCU, it integrates a 24-bit Delta-Sigma ADC, a dedicated bio-impedance (EIS) measurement circuit, and an LCD driver, providing a complete reference for blood-glucose (BGM) mass-production designs. It also extends to bio-impedance, material moisture, and other electrochemical measurement scenarios.

- Read the docs —
1.doc/BH67F2476_95迁移BH67F2493指南.pdf(for migrating customers) - Prepare hardware — use the BH67F2493 EVM; hardware files under
2.board/ - Connect the debugger — board ←→ e-Link Pro2 ←→ PC
- Build an example — open an example project under
3.code/BH67F2493_Driver/example/in HT-IDE3000, then Build All - Download & run — flash to the MCU via e-Link Pro2 and run
- Measure & verify — follow the glucose example; verify first with a test-strip model board (known reference impedance; design files in
2.board/8Pin_Strip_V1.1.zip), then run real measurements
- Resource pack version: based on the BH67F2493 BGM design as of 2026-06-01.
