User Manual

1. Overview 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. Table 2 provides the specifications of hOme_earth_module 1. Pin Definitions 1.1 Pin Layout Figure 1: hOme_earth_module Pin layout 1.2 Pin Description hOme_earth_module has 4 pins. See pin definitions in Table 3. Table 3: Pin Definitions Name No. Type Function VCC 1 P Power supply RXD 2 I/O U0RXD TXD 3 I/O U0TXD GND 4 P Ground 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 co-processor 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. FCC LABEL: FCC ID: 2ANVP-W5X6X FCC STATEMENT This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: 1) This device may not cause harmful interference 2) This device must accept any interference received, including interference that may cause undesired operation. 3.USER MANUAL HOme_earth_module connect to the device via UART and protocol, and we could use PC to download the firmware and check the information from the module. When download the firmware, please connect GPIO0 to GND ( Short jumper on J2)
Federal Communication Commission Statement (FCC, U.S.)This equipment has been tested and found to comply with the limits for a Class B digitaldevice, pursuant to Part 15 of the FCC Rules. These limits are designed to providereasonable protection against harmful interference in a residential installation. Thisequipment generates, uses and can radiate radio frequency energy and, if not installedand used in accordance with the instructions, may cause harmful interference to radiocommunications. However, there is no guarantee that interference will not occur in aparticular installation. If this equipment does cause harmful interference to radio ortelevision reception, which can be determined by turning the equipment off and on, theuser is encouraged to try to correct the interference by one of the following measures:- Reorient or relocate the receiving antenna.- Increase the separation between the equipment and receiver.- Connect the equipment into an outlet on a circuit different from that to which thereceiver is connected.- Consult the dealer or an experienced radio/TV technician for help.FCC Caution:Any changes or modifications not expressly approved by the party responsible forcompliance could void the user's authority to operate this equipment.IMPORTANT NOTESFCC Radiation Exposure Statement:This equipment complies with FCC radiation exposure limits set forth for an uncontrolledenvironment. This equipment should be installed and operated with minimum distance20cm between the radiator & your body.Co-location warning:This transmitter must not be co-located or operating in conjunction with any otherantenna or transmitter.Limited Channels fixed for use in the US:IEEE 802.11b or 802.11g or 802.11n(HT20) operation of this product in the U.S. isfirmware-limited to Channel 1 through 11. IEEE 802.11n(HT40) operation of this productin the U.S. is firmware-limited to Channel 3 through 9.OEM integration instructions:This device is intended only for OEM integrators under the following conditions:The antenna must be installed such that 20 cm is maintained between the antenna andusers, and the transmitter module may not be co-located with any other transmitter orantenna. The module shall be only used with the external antenna(s) that has beenoriginally tested and certified with this module.As long as 3 conditions above are met, further transmitter test will not be required.However, the OEM integrator is still responsible for testing their end-product for anyadditional compliance requirements required with this module installed (for example,digital device emissions, PC peripheral requirements, etc.).Validity of using the module certification:In the event that these conditions cannot be met (for example certain laptopconfigurations or co-location with another transmitter), then the FCC authorization for thismodule in combination with the host equipment is no longer considered valid and theFCC ID of the module cannot be used on the final product. In these circumstances, the
OEM integrator will be responsible for re-evaluating the end product (including thetransmitter) and obtaining a separate FCC authorization.End product labeling:This transmitter module is authorized only for use in device where the antenna may beinstalled such that 20 cm may be maintained between the antenna and users. The finalend product must be labeled in a visible area with the following: “Contains TransmitterModule FCC ID: 2ANVP-W5X6X.Information that must be placed in the end user manual:The OEM integrator has to be aware not to provide information to the end user regardinghow to install or remove this RF module in the user's manual of the end product whichintegrates this module. The end user manual shall include all required regulatoryinformation/warning as show in this manual.
