Both sides.

The face: Charizard roaring in front of a red moon, in gold, white and red on black, framed as a trading card, with HP 120, four energy windows and a fire icon along its top.
Fig. 02 · FaceCharizard in gold, white and red. The four energy windows under HP 120 are four LEDs, shining through.
The back: the parts round Charizard's head, drawn in white and red rising out of smoke and flame, both pin rows named, and the battery and USB-C labelled as its legs.
Fig. 03 · BackEvery part round the dragon's head, every pin named, its legs the battery and USB-C.

Charizard's Base Set card has the 120 HP this board prints, and a Fire Spin that hits for 100 by discarding two of its own Energy cards.
