Introduction:This main control board LUNO BLE4.0 uses LGT8F328P as the core main control and carries a wireless serial communication low-power 4.2 Bluetooth function IC. It is compatible with ArduinoUNO and is compatible with BLEUNO and is used in the ArduinoIDE compilation environment.Supports DIY mode and provides a wonderful experience when using it.The maximum main frequency of the internal crystal oscillator is 32M.LGT8F328P is compatible with the AVR instruction set and has better performance than ATMEGA328P.Add USB fuse to protect computer port from damage.Provide a professional technical team and complete website information to serve you at any time.What is LGT8F328P?LGT8F328P is a chip compatible with AVR and Atmega328P instruction sets. After loading the Arduinosoftware support package, you can use the ArduinoIDE for programming. Usage methods and 99.9% application scenarios can replace the Atmega328P chip.LGT8F328P parameters:1. LGT8F328P enhances the 8-bit RISC core and supports 16-bit digital operation expansion. In the 1.8 V-5.5 V operating range, the center frequency can reach 32MHz;2. Internal LGT8F328P 32K bytes of FLASH program memory, 2K bytes of data SRAM, integrated control logicsimulates FLASH as EEPROM. Part of the program FLASH can be divided into data FLASH space according to application needs, and access to similar EEPROM interfaces is achieved through the EEPROM controller;3. LGT8F328P integrates a large number of analog peripherals, including 12-bit ADC, programmable gain differential amplifier, and high-precision internal reference voltage 1.024/2.048/4.096V. 8-bit DAC and high-speed analog comparator; at the same time, LGT8F328P also integrates a commonly used digital interface controller, supporting multi-channel complementary PWM output and dead zone control;4. The architectural design of LGT8F328P is relatively new, and its peripheral functions are much stronger than Atmega328P. In particular, the encryption capabilities of this program far exceed those of the Atmega328P.5. Portable line serial communication low-power 4.2 Bluetooth IC; communication interface adopts UART serial port, receiving sensitivity -96dBM, communication distance up to about 45m, transmitting power -20dBM-4dBM, baud rate 9600~115200. The serial port transparent transmission rate reaches The overall working performance of 4KB/S far exceeds that of CC254
