STC15W204S learning board is designed for 51 single-chip learning, onboard common resources, can meet most of the learning needs, as detailed below:
1. All IO ports are led out
2. On-board LED controlled by one chip, connected to IO port P3.2, can be used for IO port output, PWM wave modulation and other experiments
3. On-board patch switch, connected to IO port P3.3, can be used for IO port input, interrupt and other experiments
4. The external chip switch and LED of IO port do 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 host computer communication (with timer matching) and IO port input and output experiments
6. With the test program
