Features:  compatible boards usually use Microphip microcontrollers, but just like GD32 cloning STM32, some companies are making MCU clones, usually with some improvements. LogicGreen's LGT8F328P microcontrollers (mostly) are designed with ATMega328P microcontrollers and add functions such as DAC output, PWM specific functions, computational accelerator (DSC). The clock speed of the MCU is also double (32 MHz).    Keyes LGT8F328P control board is a development board based on LGT8F328P chip. It is compatible not only with OCROBOT 0.1.2 IDE, but also with IDE. Before using, we need to install driver for the USB serial port chip of the control board. The USB serial port chip of the control board is HT42B534-1.    The control board uploads code and communicates via the Micro USB interface, for which we provide a Micro USB cable in particular. At the same time, in order to facilitate customers to connect the sensor module with the control board, some of the main signal terminals of our special board control board are extended to the 3IN connection mode (GNC VCC signal terminal), in which the voltage of VCC terminal is 5V.    Specification:  Main control chip: LGT8F328P;  USB serial port chip: HT42B534-1;  Input Voltage: DC 5V (Micro USB Power Supply);  Output Current (Total): 80mA;  Common port drive current: 12 mA;  Digital ports (27): RX0 (D0) TX1 (D1) D2-D13 A0 (D14) A1 (D15) A2 (D16) A3 (D17) A4 (D18) A5 (D19) E1 (D20) E3 (D21) SWC (D22) SWD (D23) E4 (D24) E5 (D25) AREF (D26);  Analog port (8): A0-A5 A6 (PE1) A7 (PE3) (12 bit 4096);  Working frequency: 16MHz;  With three LED lights: D13 indicator, power indicator and program burning indicator.  With a reset button;  With a Micro USB port: for uploading code and power supply;    Package Included:  1 x Open Source Control Board;  1 x Cable
