Remote control / live channel monitor for Blackmagic ATEM devices
ATEM Tally is an open-source printed circuit board by SimonHGR, from the SimonHGR/ATEM-Tally repository on GitHub. It is a 2-layer board with 25 parts on 26 nets, routed with 159 tracks and 2 vias.
Its parts include 8 resistors, 5 connectors, 4 transistors, 4 switches and 2 capacitors. It belongs with the ESP8266 boards of this library.
Remote control / live channel monitor for Blackmagic ATEM devices
Uses ESP 8266 to select one of four inputs on the ATEM switcher, and light a "tally" lamp to indicate which channel is selected.
Operates using the Blackmagic Router Control Protocol described in this video

25 parts. 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 SimonHGR/ATEM-Tally repository on GitHub, at the commit this page was made from: the board is ATEMTally.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 SimonHGR before reusing the design.
