ATtiny85 Micro Mini USB MCU Development Board Module HW-019B

This development board is based on Microchip's ATtiny85. The high-performance, low-power Microchip 8-bit AVR RISC-based microcontroller combines 8KB ISP flash memory, 512B EEPROM, 512-Byte SRAM, 6 general purpose I/O lines, 32 general purpose working registers, one 8-bit timer/counter with compare modes, one 8-bit high speed timer/counter, USI, internal and external Interrupts, 4-channel 10-bit A/D converter, programmable watchdog timer with internal oscillator, three software selectable power saving modes, and debugWIRE for on-chip debugging. 

Specifications: 

• Support IDE 1.0+(OSX / Win / Linux).
• Power is supplied via USB or external power supply - 5V or 7-16v (auto select).
• Onboard 150mA 5V voltage regulator.
• Built in USB (and serial debugging).
• 6 I / O pins (only 2 pins are used for USB when the program actively communicates via USB; otherwise, all 6 pins can be used even if the program is programmed via USB).
• 8K flash memory (about 6K after boot loader).
• I2C and SPI (relative to USI).
• PWM on 3 pins (software PWM may be more).
• ADC on 4 pins.
• Power LED and test / status LED.
