Key Features: First chip-sized Arduino compatible module that lets you see what your Arduino is thinking using a built-in OLED display 64x48 Pixel OLED Display and 32KB Flash Memory Arduino IDE 1.0+ Compatible Fits nicely into a breadboard to make prototyping easy Bare module only; MicroView Programmer not included The MicroView is the first chip-sized Arduino compatible module that lets you see what your Arduino is thinking using a built-in OLED display. With the on-board 64x48 pixel OLED, you can use the MicroView to display sensor data, emails, pin status, and more. It also fits nicely into a breadboard to make prototyping easy. The MicroView also has a full-featured Arduino library to make programming the module easy.In the heart of MicroView there is ATMEL’s ATmega328P, 5V & 3.3V LDO and a 64x48 pixel OLED display, together with other passive components that allow the MicroView to operate without any external components other than a power supply. Additionally, the MicroView is 100% code compatible with Arduino Uno (ATmega328P version), meaning the code that runs on an Arduino Uno will also be able to run on the MicroView if the IO pins used in the code are externally exposed on the MicroView.Item Specifics64x48 Pixel OLED DisplayATmega328POperational Voltage: 5VVIN Range: 3.3V - 16VDigital I/O Pins: 12 (3 PWM)Analog Inputs: 6Breadboard Friendly DIP PackageFlash Memory: 32KBArduino IDE 1.0+ CompatibleBreadboard and USB cable not includedMicroView programmer is sold separately
