1.1 Brief Introduction

The E76-433M20S is a independently developed
433MHz SMD wireless module based on EFR32
manufactured by Silicon Labs.
Internal integration of 32-bit ARM microcontroller
and high-performance wireless transceiver. This series of
products use high precision wide temperature crystal and
40MHz industrial grade high precision low temperature
drift active crystal oscillator to ensure its industrial
characteristics and stability. The module brings out all the
IO ports of the microcontroller. The chip comes with a
high-performance 32-bit ARM® Cortex®-M4 core,
integrated internal power amplifier, powerful peripherals and up to 31 GPIOs for multi-faceted development. EFR32 has
great potential to become the preferred wireless controller for future intelligent furniture, Internet of Things
transformation and industrial automation. We used a 40MHz high precision low temperature drift active crystal.
Because this module is a pure hardware SoC module, users need to program it before they can use it.
