3Pcs ATMega32U4 BS Micro Pro Micro Leonardo Development Board

Description BS Micro is based on the ATmeag32U4 Micro controller board It owns 14 general purpose digital input output pin five can be used as a PWM output 6 can be used as an analog input On board with 16 MHZ crystals and A USB type A interface based on PCB In addition to A 3 3 V power supply output independently it will not affect the work of MCU power output the output power depends on the USB port power supply capacity but is not higher than 1 5 A Bat has burn bootloader so it is compatible with theIDE Although it is small in size but it has rich interface make it not only has the function of the traditional controller and realize the function of the mouse keyboard on the computer a serial port function and can realize communication with computer directly It like most other MCU control board is a big difference between programming does not need additional use programmer directly from the USB programming This is not only convenient stable and reliable also save the expense of a programmer Product features Master ATmega32u4Working voltage 5 vDigital I o number 14PWM output number 5Analog input number 6Other peripherals USB UART I2C SPI 3 3 V Power Supply Output40 ma IO driving force Flash 32 KB ATmega32u4 including 4 KB is bootloader footprintSRAM 2 5 KB ATmega32u4 EEPROM 1 KB ATmega32u4 16 MHZ frequency Width 800 mils 20 3 mm Length 1200 mils 30 5 mm Weight 2 5 g not including packaging and accessories Package included 3
