With the LED deck and a Crazyflie 2.x, we are able to make real pieces of art, like in the light paintings in this blog post or even the Mona lisa. However, these fun projects do require an external positioning system, since we used the lighthouse positioning deck.
How about using the LED-deck in the combination with the Flow deck v2? A while ago we managed to do this by drilling a couple of holes in the LED deck in this hackster project. However, if you are fine with putting the LED deck on the top, there might be an easier way to achieve this combination.
What do you need for this:
What we are essentially doing, is that we are flipping the pin-layout of the LEDdeck so that it is compatible with the crazyflie to be put on the top.
The image below shows how you should solder the wiring. The Gnd (ground), IO2, OW (deck memory), and VCOM (power supply). Please check out this page to confirm for yourself what the pinout is for the expansion decks are.
We did not connect IO3 on purpose since the Flow deck v2 is already using this for it's own, or else the LED deck and Flow deck will conflict with each other's communication with the Crazyflie.
The battery holder deck can be glued on the LED-deck or attached with some tape.The wiring and soldering is done a bit crude for now to clearly show how to do this, however if you would like the wiring not to be shown as clearly as now, it should be very easy to do with thinner wires and basic soldering skills.
