The Arduino 4 Relays Shield is a solution for driving high power loads that cannot be controlled by Arduino's digital IOs, due to the current and voltage limits of the controller.
Discover the Adafruit ESP32-S2 Feather: a compact, powerful IoT development board with Wi-Fi, Bluetooth, expandable storage, and easy programming support.
This powerful shield features the VS1053, an encoding/decoding (codec) chip that can decode a wide variety of audio formats such as MP3, AAC, Ogg Vorbis, WMA, MIDI, FLAC, WAV (PCM and ADPCM).
The SparkFun RedBoard combines the simplicity of the UNO’s Optiboot bootloader (which is used in the Pro series), the stability of the FTDI (which we all missed after the Duemilanove was discontinued) and the R3 shield compatibility of the latest Arduino
