Module IntroductionModule parameters

The EH-MC25 is Bluetooth 5.2 low energy and 2.4GHz proprietary multi-application module, It is combine the excellent performance of a leading RF transceiver with a low-power ARM Cortex-M0+, power management unit, ADC, and smart I/O distribution controller.

The embedded ARM Cortex-M0+ CPU enables developers to achieve 32-bit performance at an 8-bit price point, bypassing the step to 16-bit devices. By using a single-cycle multiply option and a 2-stage pipeline, the ARM Cortex-M0+ makes program execution simple and highly efficient.

EH-MC25 comes with a PCB antenna (ANT). EH-MC25B comes with an external antenna. A wide selection of module variants are available for customers as shown in Table 1
