The 2 shared IO pins have 2 more analog inputs and one more PWM output. The 3 independent IO pins have 1 analog input and 2 PWM output as well.

5 GPIO - 2 shared with the USB interface.

No need to unplug/replug the board every time you want to reset or update!

Reset button for entering the bootloader or restarting the program.On-board green power LED and red pin #1 LED.Power with either USB or external output (such as a battery) - it'll automatically switch over.Up to 16V input, reverse-polarity protection, thermal and current-limit protection.Onboard 3.3V or 5.0V power regulator with 150mA output capability and ultra-low dropout.~5.25K bytes available for use (2.75K taken for the bootloader).

Micro-USB jack for power and/or USB uploading, you can put it in a box or tape it up and use any USB cable for when you want to reprogram.USB bootloader with a nice LED indicator looks just like a USBtinyISP so you can program it with AVRdude (with a simple config modification) and/or the Arduino IDE (with a few simple config modifications).Internal oscillator runs at 8MHz but can be doubled in software for 16MHz.

ATtiny85 on-board, 8K of flash, 512 bytes of SRAM, 512 bytes of EEPROM.

I would like in the future to connect two arduinos through both bluetooth modules in order to send and receive message each one from the other one. When i connect to bluefruit bluetooth module from my phone program says UART CAPABLE but when i try to see message "Comunicando" in terminal of Adafruit app, this says Uart protocol can not be initialized. I installed Adafruit Bluefruit LE Connect app in my phone.īlue led of CONN in bluetooth module is blinking (it is assumed that is sending message) as same time that RX in arduino is blinking. I plugged pin 0 (TX) from arduino uno to RXI of bluefruit module, pin 1 (RX) from arduino to TXI of bluefruit module.

Hello I'm trying to send just one message through Adafruit Bluefruit LE UART Friend Module like this->
