ATMega32U4 BS PMicro Pro Micro LeonardoCompatible Development Board

Description BS PMicro is a ATmeag32U4 based microcontroller board It has 16 universal digital input output pins 6 of which can be used as PWM outputs and 7 can be used as analog inputs On the board there are 16Mhz crystal and a USB Micro interface In addition there is a 3 3V independent power supply output and its power output will not affect the MCUs work the output power depends on the USB port power supply capacity but the maximum is not higher than 1 5A The board has burned s bootloader so its compatible with s IDE Although it is small but it has a rich interface not only to the traditional controller function as well as in the computer to achieve the mouse keyboard function serial port function and can directly communicate with the computer It have a big difference to most other MCU control board is that programming does not require additional programmer you can directly use USB programming This is not only convenient stable reliable but also save a programmer money Features Master ATmega32u4Operating voltage 5VNumber of digital IO 16Number of PWM outputs 6Number of analog inputs 7Other peripherals USB UART I2C SPI 3 3V Power Supply OutputIO driving force 40mAFlash 32KB ATmega32u4 where 4KB is occupied by bootloaderSRAM 2 5 KB ATmega32u4 EEPROM 1 KB ATmega32u4 Frequency 16MhzSize 23 50 20 34mmPackage included 1 x ATMega32U4 BS PMicro Pro Micro Leonardo
