The product is a continuous glucose monitoring (CGM) development board based on the CGM MCU BH66F2475 and Bluetooth 5.3 MCU HT32F67595. It offers three interfaces: SPI, I2C, and UART.
The product has a built-in 3-electrode sensor. When glucose reacts with the enzyme in the sensor, it produces an electrical signal, which is then converted into a blood glucose value.
The product requires a CR1226 battery as its power source.
Holtek designed an application to monitor data more easily when developing products.
The application only supports iOS mobiles. You can search ‘HT CGM’ on the Apple store or scan the below QRcode to download it.
