Overview
Payload is an open-source printed circuit board by dcowden, from the dcowden/battlepoint repository on GitHub. It is a 2-layer board of 81.3 × 81.3 mm with 12 parts on 45 nets, routed with 110 tracks and 7 vias.
Its parts include 11 connectors and 1 IC. It belongs with the ESP32 boards of this library.

TODO
Electrical
- Shield cannot extend over UNO USB block
- Owner and Capture LED strands reversed
- More room
- more room for heat sink ( was hitting stuff around it)
- add connx2 for switch
- add 2x 1000uf caps near LED strips
- BUG: vmonitor connects to vin of regulator, not vin of arduino
- BUG: not enough room for terminal block
- Change terminal block footprint to conn JST XH
- BUG: audio: chnage to JSTx05, add ground pin
- Button board: latch has to go inwards
- switch to microusb breakout and USB for lights, and TYPEA USB for each led strand
- merge 620 and 330 ohm (R4 and R5) to 1x 1k instead
Mechanical
- More room between OLED board and Button board ( they overlap now)
- Bigger Channels for lights. Maybe just keep the back partially open
- more room around buttons. they tend to get tangled with wires
- The bezel needs to cover the non-interactive part of the OLED display
Programming
- make # of lights on each strand configurable
- change defaults to 20 lights on each strand
- remove debug
- in cp mode, we have captured the control point shouldnt play, since victory is immediate
- in KOTH, the countdown gets behind the numbers. better to just play the countdown as one recording
- record new sounds
Enhancements
Easier to make and higher mast
The led strips should be in a mast that extends upwards, making it easier to make and better visibilty too
Three Player Mode
Three player mode would require another LED strip and another button. The rules are as follows:
in KOTH each color tracks separately. the first time to run their timer out wins in AD mode two teams are attacking and one is defending. But the winning team is the one which accumulates the most time towards the capture. in CP mode the point tracks all three colors separately

Questions
How big is the Payload PCB?
It measures 81.3 × 81.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Payload use?
12 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.
Where can I download the Payload KiCad files?
From the dcowden/battlepoint repository on GitHub, at the commit this page was made from: the board is payload/kicad/payload.kicad_pcb and its schematic control_squares/kicad/ControlSquare.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Payload design in my own project?
Its repository states no licence, so its author keeps all rights: ask dcowden before reusing the design.
