You can also find some more details on MXCHIP EMW3165 Download page. EMWE-3165 Development BoardĮMWE-3165 is the baseboard for EMW3165 module with an NFC antenna, JTAG, USB, DB9 interface (serial), buttons, as well as supports for battery. Espressifs ESP-WROOM-02 module has gained the CE certification from the EU, the FCC certification from the US, and the TELEC certification from Japan.
I could not find information about the software development tools, but it’s likely you can use the same tools as for EMW3162 namely Broadcom WICED firmware development kit, or MXCHIP MICO (Mico-controller based Internet Connectivity Operation System). EMW3165 also appear to lack SPI and I2S found on EMW3162.
More details can be found in the datasheet.The main difference with EMW3162 module is the STM32F4 processor replacing STM32F2 processor, 2MB on-board flash (EMW3162 used 1MB on-chip flash only), and a smaller footprint.
MCU – STMicro STM32F411CE ARM Cortex M4 micro-controller 100 MHz with 512KB flash, 128KB RAM, DSP, and FPU On-board WiFi module for wireless communication supports AP mode and Station mode.The company has now launched another WiFi module called MXCHIP EMW3165 with an STM32F4 Cortex M4 MCU 100 MHz, FCC certification, and listed for $7.95. It’s more capable than ESP8266 modules but also around 3 times more expensive. If antenna change is a must, the FCC provides a class 2 permissive change procedure provided the new Antenna is of similar gain.A few months ago, Seeed Studio started selling MXCHIP EMW3162 Wi-Fi module with a STM32F2 Cortex M3 MCU clocked at 120Mhz for $9.95.Class B: Digital Device for use in a residential environment not withstanding use in commercial, business and industrial environments.Class A: Digital Device for use in a commercial, industrial or business environment.Letter of Authorization from Module Partner (Customer or Lab will request from Module Partner).Request for change in FCC ID to Module Partner FCC ID for intentional radiation.The module chip is ESP8285, its built-in storage is 16Mbit, and it has various certifications such as FCC/CE/SRRC. FCC compliance declaration at Device level (47 CFR chapter 1 subpart B) TYWE2S is a low-cost, small-size WiFi module.FCC testing such as unintentional radiation etc.Additional testing may be required depending class A or B designation (below).layout/dxf file and antenna design that Module partner provides). For Reference Certified, customers must copy the module partner design exactly (ex. Assumptions: Customer doesn’t change any portion of the Pre-Certified module design.
