Description
Expansion module with a DAC/ADC converter and a camera dedicated to FireBeetle ESP32. It is equipped with an audio output based on the I2S NAU8822 codec with an amplifier that allows you to connect 8 Ω speakers with a power of 1 W or headphones. The board also has a microphone and a Jack socket that allows you to connect an external microphone, and thanks to the use of a microSD card slot, the user can easily save data. The camera included in the set is based on the OV7725 sensor with a resolution of 640x480 px and communicates via the SCCB interface. Such a large capacity of the module makes it perfect both as an MP3 player, voice recorder and a camera used for image recognition. Full documentation with examples of use is available on the product page.
