An ATtiny13 development board

In this article we look at another development board, this time its a compact board aimed at the Attiny13


lets look at the Attiny13 microcontroller first and some basic specs

The 8-bit AVR® RISC-based microcontroller features 1 KB of ISP Flash, 64B EEPROM, 64B SRAM, 32B register file, and 4-channel 10-bit A/D converter. The device achieves up to 20 MIPS throughput at 20 MHz at 1.8-5.5V operation.

Now lets look at the development board we bought which contained this microcontroller

The ATtiny13 development board is a learning board designed specifically for the ATtiny13.

The working voltage of the board can be selected to either 3.3V or 5V through the jumper on the board.

All the pins of the chip are led out by pin headers

The board has the following resources and features .

Onboard resources:

  • Reset button
  • Two buttons
  • Three LEDs
  • ADC potentiometer
  • 5V or 3.3V working voltage selection via a jumper
  • Power button
  • ICSP 10 way header
  • DC power jack
