EMW3072
1. Product Introduction
EMW3072 is a cost-effective embedded W-Fi module launched by Shanghai Qingke (MXCHIP). It is highly
integrated with ARM CM4F, WLAN MAC/Baseband/RF, with a maximum main frequency of 240MHz, built-in
256KB SRAM, 2M FLASH and 3.3V single power supply.
The following diagram is the hardware block diagram of EMW3072 module, which mainly includes four parts:
CM4F main core
WLAN MAC/BB/RF/ANT
SWD debugging
Power management
Among them:
1. ARM CM4F CPUworking frequency up to 240MHz, internal integration 256K SRAM, 2MB FLASH,
support high-speed UART, I2C, SPI, PWM, and multiple GPIO ports.
2. Extra-chip SPI Flash with maximum support of 128MB for custom firmware development.
3. Supporting PCB antenna and IPEX external antenna
4. Input typical voltage: DC 3.3V
