# Recommended boards with a built-in level shifter
8-
To ensure the LEDs will work properly with the Pico board, a 3.3V to 5V level shifter is needed. You can use an external one e.g. SN74AHCT125N or just buy a model of rp2040 that already has it built-in: Adafruit Feather RP2040 Scorpio (output: GPIO16-23), Adafruit ItsyBitsy RP2040 (output: GPIO14), Pimoroni Plasma 2040 (GPIO14-15), Pimoroni Plasma Stick 2040 W (GPIO15) or Pimoroni Plasma RP2350 (GPIO14-15).
