Introduction:

The LF-WM03 module is alow-cost, high-performance WIFI module based on the LF686C(32-

bit RISC CPU with FPU) to create a cost-effective IoT module for customers. Figure 1 shows the

hardware block diagram of the LF-WM03 module, consisting of the following three major parts:

 32-bit RISC-V core CPU

 WiFi RF module

 Enrich peripherals

Figure 1 LF-WM03 hardware block diagram

thereinto:

 32-bit RISC-V core CPU with up to 192MHz operating frequency

 Internal integration 276KB SRAM,128KB ROM

 Supports high-speed UART,I2C,SPI,PWM,andmultiple GPIO portes

 Enter typical voltage:3.3V
