## Power, Power and Power!
Having a good power supply is CRITICAL, and it is highly recommended, for chains of LED Panels to have a 2000uf capacitor soldered to the back of each LED Panel across the [GND and VCC pins](https://github.com/mrfaptastic/ESP32-RGB64x32MatrixPanel-I2S-DMA/issues/39#issuecomment-720780463), otherwise you WILL run into issues with 'flashy' graphics whereby a large amount of LEDs are turned on and off in succession (due to current/power draw peaks and troughs).
Refer to this guide written for the [rpi-rgb-led-matrix library](https://github.com/hzeller/rpi-rgb-led-matrix/blob/master/wiring.md#a-word-about-power) for an explanation. Refer to this [example](https://github.com/mrfaptastic/ESP32-RGB64x32MatrixPanel-I2S-DMA/issues/39#issuecomment-722691127) issue of what can go wrong with a poor powersupply.
