HOme_earth_module is a generic Wi-Fi+BT+BLE MCU module that targets a wide variety of
applications, ranging from home appliances, such as air condition, humidifier and refrigerator.
At the core of this module is the ESP32 chip. The chip embedded is designed to be scalable and
adaptive. There are two CPU cores that can be individually controlled, and the clock frequency is
adjustable from 80 MHz to 240 MHz. The user may also power off the CPU and make use of the
low-power co-processor to constantly monitor the peripherals for changes or crossing of
thresholds.

2. Functional Description

This chapter describes the modules and functions integrated in hOme_earth_module.

2.1 CPU and Internal Memory

ESP32-D0WDQ6 contains two low-power Xtensa® 32-bit LX6 microprocessors. The internal
memory includes:

● 448 kB of ROM for booting and core functions.

● 520 kB (8 kB RTC FAST Memory included) of on-chip SRAM for data and instruction.

- 8 kB of SRAM in RTC, which is called RTC FAST Memory and can be used for data
storage; it is accessed by the main CPU during RTC Boot from the Deep-sleep mode.

● 8 kB of SRAM in RTC, which is called RTC SLOW Memory and can be accessed by the co­processor during the Deep-sleep mode.

● 1 kbit of eFuse, of which 256 bits are used for the system (MAC address and chip
configuration) and the remaining 768 bits are reserved for customer applications, including
Flash-Encryption and Chip-ID.

2.2 Crystal Oscillators

The ESP32 Wi-Fi/BT firmware can only support 40 MHz crystal oscillator for now.
