Microcontroller minimum system board-IAP15W4K58S4

product description

       The use of enhanced 51 microcontroller makes the module more simple and easy to use while having high performance. The hardware supports practical peripherals such as ADC, PWM, SPI, CCP, and serial ports. It is also compatible with the Arduino UNO R3 interface and is compatible with more modules. It is a good helper for microcontroller learning.

Features

• This module uses 51 microcontroller, model is IAP15W4K58S4.
• Integrated USB to serial port (TTL) circuit, can be used independently.
• 5V, 3.3V, and GND pin headers are reserved to power external modules.
• Three independent buttons and two independent LED indicators for convenient experimentation.
• There are four sets of expansion interfaces for easy connection of external modules.
• The power supply of the microcontroller can be selected from 3V or 5V, and a power consumption test interface is reserved.
• There are two ways to download programs, cold start download and automatic download.
• There is a four-wire OLED interface with IIC communication method.
• Compatible interface for Arduino UNO R3.
