Overview
This development board is based on the IoT application MCU development board featuring the RISC-V core W806 by Winner Micro. It comes equipped with an RST reset button, a Boot upgrade button, and a USB 2.0 interface. The expansion interfaces support peripherals such as Touch, UART, PWM, GPIO, SPI, I2C, I2S, ADC, LCD, and more, making it suitable for IoT application developers to evaluate the W806 chip and rapidly build application examples.
Function Description
The main components, interfaces, and control methods of the HLK-W806-KIT development board are as follows.
The description of the main components of the HLK-W806-KIT development board is shown in the table below (starting from the top left corner in a clockwise direction).
Main Components |
Basic Introduction |
LDO |
5V to 3.3V LDO (Low Dropout)regulator chip. |
W806 |
The main control chip of the development board, with WiFi, Bluetooth, and other functions. |
RST-Key |
System reset button. |
BOOT |
Download mode button. Press the BOOT button, then insert the USB cable into the UART0 port. After releasing the BOOT button, it will enter the download mode. |
I/O |
All pins of the W800 are brought out to the development board’s pin headers. Users can program the W800 to implement functions like PWM, ADC, DAC, I2C, and I2S. For details, please refer to Pin Description. |
Micro-USB 2.0 |
The default USB port on the development board, which can be used as a power supply or as a communication interface between the PC and the development board. |
Power Options
The development board can be powered by any of the following three methods:
Micro USB power (default)
5V / GND pin power
3.3V / GND pin power
Warning
The above power modes should not be connected simultaneously, as this may damage the development board or power supply.
