WT2605XB04-R audio recording module is an intelligent audio data transmission, recording and MP3 audio playback product independently developed by Waytronic. It is a low-cost and high-efficiency recording scheme with the characteristics of high integration, small size, low power consumption and stable transmission. Only a few components can be added to the periphery of the module to realize high-quality audio playback. Self-drive-free mode, no complicated bottom operation, convenient use, stability and reliability are the biggest features of this product. In addition, the chip is also a deeply customized product, a low-cost solution specially developed for the field of recording and playing.
WT2605XB04-R mainly has four functions: line recording, MIC recording, MP3 function and UART serial port control. Built-in Flash module, which can plug-in U disk and TF card.
The internal structure of the module: audio chip, Flash, 26M crystal oscillator, antenna and 1W power amplifier (when not in use, it can be directly connected to the external output through resistors).
The pins are arranged in the order shown above.
