1.Features
Convenient hardware design: the aluminum alloy USB flash drive shell is easy to carry and effectively prevents static electricity and falling and touching. The interface definition is directly labeled on the shell, which is convenient for users to quickly identify and connect. Equipped with standard USB interface, can be directly connected to the computer USB port.
Rich power supply function: support 5V power output, and the output I/O ports are protected, can provide 5V/3.3V dual power supply, 5V maximum output 500mA, 3.3V maximum output 300mA, can be convenient for the target board power supply to adapt to the different voltage requirements of the device. On-board 500mA self-recovery fuse can effectively prevent the harm caused by short-circuit to protect the computer motherboard and other devices.
Powerful debugging function: support full-speed operation, single-step debugging, breakpoint debugging and other debugging methods, you can view the IO status, variable data, etc., to help developers quickly locate and solve problems.
