EzerLonginus/ATTiny412-BreakoutSimple breakout for the ATTiny412 using USB for uploading and serial comms
ATTiny412-Breakout is an open-source printed circuit board by EzerLonginus, from the EzerLonginus/ATTiny412-Breakout repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 22 × 22 mm with 26 parts on 32 nets, routed with 285 tracks and 27 vias.
It is built around the ATTINY412-SSN, CH340E and USBLC6-2SC6. Its parts include 9 resistors, 4 ICs, 4 diodes, 4 connectors and 3 capacitors. It belongs with the interfaces and adapters boards and the AVR (ATmega, ATtiny) boards of this library.
Simple breakout for the ATTiny412 using USB for uploading and serial comms
This board is a simple breakout for the ATTiny412. This allows for programming and UART serial communications through a USB interface. Included in breakout is a power led indication, and a few feedback LEDs for UART and UPDI programming. UPDI and UART need to be selected via switch on the front of the breakout.
I wanted a way to quickly and easily test some software with the attiny412 (or similar avr chip), and not have to have a programmer and separate power source connected to chip. This usually involved using a USB connector for power (sometimes doubling as a serial comms port) and some UPDI programmer to upload code. This board will hopefully just allow me to use the USB for all functionality and to make development a little be cleaner and easier.

26 parts, built around the ATTINY412-SSN, CH340E and USBLC6-2SC6. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the EzerLonginus/ATTiny412-Breakout repository on GitHub, at the commit this page was made from: the board is hardware/attiny412_breakout/attiny412_breakout.kicad_pcb and its schematic hardware/attiny412_breakout/attiny412_breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
