mango unos CH340 Development board For arduinos unos LGT8F328P-QFP32 CHIP

<p>This is an Arduino UNO compatible board based on the domestic chip LGT8F328P chip. It is an enhanced 8-bit RISC core. It is optimized for the original architecture. The instruction execution speed is faster. At the same time, it optimizes the flash part, adds timer 3, built-in crystal oscillator, and increases DAC output. The main frequency can be up to 32M. Lower power consumption.</p> <h2 id=""lgt8f328p和atmega328p芯片对比"">Comparison of LGT8F328P and Atmega328P chips</h2> <p>LGT8FX8P series microcontrollers currently mainly include three package chips LGT8F328P-SSOP20, LQFP32 and LQFP48.</p> <ul> <li> <p>Enhanced 8-bit RISC core, support 16-bit digital operation extension, in the working range of 1.8V – 5.5V,  <strong>support internal crystal oscillator, can run at the core frequency of up to 32MHz;</strong></p> </li> <li> <p>LGT8F328P has internal 32K bytes FLASH program memory, 2K bytes data SRAM, built-in control logic that simulates FLASH as EEPROM, can divide a part of program FLASH into data FLASH space according to application needs, and realize EEPROM-like interface access through EEPROM controller ,  <strong>if you use eerom, the total flash is only 30K, which is 2K less than his Atmega328P;</strong></p> </li> <li> <p>LGT8F328P integrates more hardware resources and peripherals, including 12-bit ADC, timer3, high-precision 1.024/2.048/4.096V internal reference voltage, 8-bit DAC and high-speed analog comparator, A8(D23), A9(24), A10( 25), A11 (D26) analog input port, D22, REST, crystal oscillator pins can be configured as GPIO ports;</p> </li> <li> <p>The LGT8F328P architecture design is relatively new, and the peripheral functions are far stronger than the Atmega328P. Especially the program encryption ability is far more than Atmega328P</p> </li> </ul> <h2 id=""技术参数"">technical parameter</h2> <table> <thead> <tr> <th align=""left"">name</th> <th align=""left"">parameter</th> </tr> </thead> <tbody> <tr> <td align=""left"">MCU</td> <td align=""left"">LGT8F328P</td> </tr> <tr> <td align=""left"">Operating Voltage</td> <td align=""left"">5V</td> </tr> <tr> <td align=""left"">Input voltage (recommended)</td> <td align=""left"">7-9V</td> </tr> <tr> <td align=""left"">FLASH</td> <td align=""left"">32KB</td> </tr> <tr> <td align=""left"">SRAM</td> <td align=""left"">2KB</td> </tr> <tr> <td align=""left"">E2PROM</td> <td align=""left"">0K, 1K, 2K, 4K configurable (shared with FLASH)</td> </tr> <tr> <td align=""left"">PWM</td> <td align=""left"">6 way</td> </tr> <tr> <td align=""left"">main frequency</td> <td align=""left"">Internal 16MHz (Max 32MHz)</td> </tr> <tr> <td align=""left"">ADC</td> <td align=""left"">6 channel 12 bit</td> </tr> <tr> <td align=""left"">DAC</td> <td align=""left"">1 channel 8 bits</td> </tr> <tr> <td align=""left"">UART</td> <td align=""left"">1 way</td> </tr> <tr> <td align=""left"">analogRead range</td> <td align=""left"">0~4095 precision</td> </tr> <tr> <td align=""left"">Internal benchmark</td> <td align=""left"">1.024V, 2.048V, 4.096V ±0.5%</td> </tr> <tr> <td align=""left"">Other peripherals</td> <td align=""left"">SPI, TWI (I2C), GUID (Global Device Number)</td> </tr> <tr> <td align=""left"">size</td> <td align=""left"">68.6mm * 53.4mm</td> </tr> </tbody> </table> <h2 id=""nulllab开发板arduino-ide支持包"">Nulllab development board Arduino IDE support package</h2> <h3 id=""方法一、网络安装"">Method 1, network installation</h3> <p>1.
