1. OUTLINE AtomU is a very small and flexible IoT speech recognition development board, using Espressif's `ESP32` main control chip, equipped with two low-power `Xtensa® 32-bit LX6` microprocessors, main frequency Up to `240MHz`. It has the characteristics of compact size, strong performance and low power consumption. Integrated USB-A interface, plug and play, easy to upload, download and debug the program. - Page 4 technology. ESP32-PICO-D4 integrates all peripheral components seamlessly, including a crystal oscillator, flash, filter capacitors and RF matching links in one single package. Given that no other peripheral components are involved, module welding and testing is not required either. As such, ESP32-PICO-D4 reduces the complexity of supply chain and improves control efficiency.
