ATtiny85 USB Development Board 180k ohm smd resistor the BTA/BTB40-41 series is usedATtiny 85 development boards are important in embedded electronics. The ATtiny85 is a small development board from the Arduino community. It contains 6 Digital pins, 4 of which are ADC compatible, and is based on the 8 pin ATtiny85 ATMEL Microcontroller. It also includes three PWM outputs and supports SPI, I2C, and USART communication. The Flash memory is 8K in size. It works on +5V and has a built in voltage regulator that can handle input voltages
