STC15W204S Micro Controller Minimum System Development Board 51 SOP8

Features:

1.All IO port all leads
2.Board all the way MCU control LED, connected to the IO port P3.2, IO port can be used for output, such as PWM wave modulation experiment
3.Onboard all the way switch chip, connected to the IO port P3.3, IO port can be used for input, interrupt and other experiments
4.IO port external chip switch and the LED does not affect the normal use of IO port
5.On-board TTL level serial port, RXD (connected to P3.0) and TXD (connected to P3.1) can be used for STC download program / serial port communication between upper and lower computer (timer required) and IO port input and output
