ESP32-S3 Zero Mini Development Board
This board is powered by the Xtensa® 32-bit LX7 dual-core processor, which runs at a high main frequency of up to 240MHz, providing a fast and efficient performance. It supports 2.4GHz Wi-Fi (802.11 b/g/n), providing reliable wireless connectivity, it includes Bluetooth® 5 (LE) for strong communication with other Bluetooth-enabled devices, and the inclusion of a USB-C port provides convenient connectivity and power options.
It's equipped with 512KB of SRAM and 384KB ROM, offering sufficient space for complex programs and applications. Additionally, it features an onboard 4MB flash memory and 2MB PSRAM, further extending its storage capabilities. This combination of memory options makes it suitable for a wide range of projects, from simple LED controls to more intricate IoT applications.
If you want to make things easier and have the header already soldered on, you can find the option to the right. Just click "With pre-soldered headers" and add it to your basket.
