 ====== HelloD1614 ======
-Based on the [[http://ww1.microchip.com/downloads/en/DeviceDoc/ATtiny1614-data-sheet-40001995A.pdf|ATtiny1614]] and inspired from the [[http://fabacademy.org/2020/labs/leon/students/adrian-torres/adrianino.html|Adrianino]], the HelloD1614 is a simple board that can be used to test the recent features of the new ATtiny microcontrollers. The board exposes the full pinout of the ATtiny1614, and offers UPDI as one of the way of programming the chip. Rearranged pinouts for I2C and the FTDI are also available.

+The board layout shows on the right side the connection to the FTDI cable, and to the bottom-right side the connection for the UPDI programmer. On the left side the I2C is exposed, also with 4.7k pull-up resistors. Additional IO is on the top. More details in the pinout.
