Out of Stock?

TinyCore 16 is permanently out of stock and will be retired soon, please use TinyCore 32 board, it doubles the flash and more GPIOs.

What is it?

Open source Arduino supported Attiny1616 breakout board with Programmer. It is small, easy to use and low power consumption. It has I2C, SPI, UART, PWM, Timers, Touch PINS, ADC, DAC, 16K Flash, 2K SRAM, 256 bytes EEPROM with 8-bit CPU running up to 20MHz all in it's tiny body! It has the smallest possible bread-board footprint. It can be programmed directly with the following methods:

• Tiny Core Programmer
• Atmel-ice programmer
• Arduno Uno or any Atmega328p based boards
• Arduno Leonardo or any Atmega32u4 based boards including Tiny Core Programmer (I will release the firmware soon)

(Warning: this board has no bootloader, it can only be programmed through programmers mentioned above.)

Feature

Arduino Support

Currently UART, I2C, SPI, basic timer functions like delay, delayMicroseconds, milis, micros are working, I'm working on adding EEPROM support.

Installation

• Install the current upstream Arduino IDE at the 1.8.7 level or later. The current version is at the Arduino website.
• Start Arduino and open Preferences window.
• Enter https://raw.githubusercontent.com/xukangmin/TinyCore/master/avr/package/package_tinycore_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
• Open Boards Manager from Tools > Board menu and install TinyCore platform (and don't forget to select your TinyCore board from Tools > Board menu after installation).

Why did you make it?

To utilize the power of ATtiny 1-Series. I haven't found any breakout board with programmer and Arduino Support.

What makes it special?

It has I2C, SPI, UART in a QFN 3x3 package with 20MHz internal oscillator. And the power consumption can go as low as 2.9μA, perfect for IoT / battery powered application.
