ecTiny841. ATtiny841 uC board.

Board documentation and tutorials.

Description:

ecTiny841 is a compact low-cost 8-bit microcontroller board which is designed to be fitted into a breadboard. It includes the connectors and minimal components to fully run the microcontroller and it also offers the option to add an external crystal to generate a reference clock signal.

The board is ideal to get familiar with microncontrollers and learn how to program a simple but yet capable 8-bit microcontroller. The chip itself has 11 general purpose input/output pins and a good bunch of built-in peripherals.

ecTiny841 features:

• Atmel 8 bit-microcontroller model ATtiny841.
• Power input: 1.7 – 5.5 Vdc.
• 8 kB FLASH, 512 Bytes of SRAM, 512 Bytes of EEPROM.
• 11 general purpose input/output pins + reset pin.
• Internal 8 Mhz oscillator, maximum external crystal of 16 Mhz @ 5Vdc.
• 1 x 8-bit timer and 2 x 16-bit timers with 2 PWM channels.
• 10-bit ADC : 12 single ended external channels and 5 internal.
• 2 x Full duplex USARTs.
• 1 x SPI master/slave interface.
• 1 x I2C slave interface.
• The board includes 100 nF and 10 uF capacitors, programming connector and external connectors for every microcontroller pin.
• Small format: 20.7 mm x 16.3 mm.

Package contents:
