MicroArd is an open-source printed circuit board by KhazAkar, from the KhazAkar/MicroArd repository on GitHub. It is a 4-layer board of 39.6 × 53.1 mm with 37 parts on 46 nets.
It is built around the FT230XQ-R, SS16HE and USBLC6-2SC6. Its parts include 15 capacitors, 8 resistors, 5 connectors, 4 diodes and 3 ICs. It belongs with the AVR (ATmega, ATtiny) boards of this library.
It's development board/breakout board with FT230XQ USB-UART interface IC adapted for UPDI interface used to program newest series of Microchip AVR utility. This board is compatible with pyudpi software, used for programming that MCU.

37 parts, built around the FT230XQ-R, SS16HE 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 KhazAkar/MicroArd repository on GitHub, at the commit this page was made from: the board is MicroArd.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask KhazAkar before reusing the design.
