ATTinyX14-development board
About the ATTinyX14-development board
ATTinyX14-development board is an open source AVR/Arduino PCB design by jenschr, published on GitHub under the MIT license. It is a 2-layer board measuring 39.4 × 16.2 mm, with 23 components from 17 distinct parts.
Its main chip is the ATTINY1614-SSNR, from the AVR/Arduino family. Other key parts include the AP2112K-3.3TRG1 and CH340E. By type, the board carries 6 resistors, 4 connectors, 3 ICs, 3 capacitors, 2 inductors and 1 diode.
It belongs with the dev boards & breakouts and usb & debug tools designs in this gallery.
From the project
Tiny breadboard compatible development board based on either ATTiny414, ATTiny814 or ATTiny1614
The board has a builtin LED on (PA5) and a button (PA4) for testing. The Serial chip has a LED on the TX line, so you can visually inspect when programming is done and finished. My primary reason for looking at this chip series was the 8-bit DAC output on PA6. Very few MCU's in this price range has a builtin DAC, so it is very handy for many types projects such as controlling devices based on voltage. One such example is controlling 0-10V motors/fans by just adding a small OpAmp circuit.

ATTinyX14-development board: common questions
What microcontroller does the ATTinyX14-development board use?
The ATTinyX14-development board is built around the ATTINY1614-SSNR, from the AVR/Arduino family.
How big is the ATTinyX14-development board?
The ATTinyX14-development board measures 39.4 × 16.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ATTinyX14-development board?
23 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the ATTinyX14-development board design files?
From the jenschr/ATTinyX14-development-board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the ATTinyX14-development board design in my own project?
Yes, under the terms of its MIT license, which jenschr chose for the repository.
Can I test firmware for the ATTinyX14-development board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
