A magic schwitchboard is a little box with four switches and four lamps colored in red, green, blue and yellow. The switches have got hats in the same colors.

Simple ISP programmer
USBtinyISP is an open-source printed circuit board by etimou, from the etimou/USBtinyISP repository on GitHub. It is a 2-layer board of 70 × 45 mm with 26 parts on 29 nets, routed with 163 tracks and 0 vias.
It is built around the ATTINY2313A-PU. Its parts include 9 connectors, 8 resistors, 4 diodes, 3 capacitors and 1 IC. It belongs with the AVR (ATmega, ATtiny) boards of this library.

It measures 70 × 45 mm and has 2 copper layers, 1.6 mm thick.
26 parts, built around the ATTINY2313A-PU. 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 etimou/USBtinyISP repository on GitHub, at the commit this page was made from: the board is hwdesign/CADfiles/USBtinyISP.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 etimou before reusing the design.
