Introduction ESP32-S3-Zero (without pin header) and ESP32-S3-Zero-M (with pin header) are tiny in size with castellated holes, making them easy to integrate into other host boards. ESP32-S3-Zero comes with an onboard Type-C USB connector, which exposes most of the unused pins in a small form factor. It adopts ESP32-FH4R2 as a system chip (SoC) that integrates low-power W-i-F--i and BLE5 with 4MB Flash and 2MB PSRAM. In addition, there is a hardware encryption accelerator, RNG, HMAC, and Digital Signature modules to meet the safety requirements of IoT and provide peripheral interfaces. Moreover, its low-power working mode supports most application scenarios such as IoT, mobile devices, wearable electronic devices, and smart homes. Board specifications Equipped with Xtensa 32-bit LX7 dual-core processor, up to 240MHz main frequency Supports 2.4GHz W--i-F--i (802.11 b/g/n) and Blue--too--th 5 (LE) Built in 512KB of SRAM and 384KB ROM, onboard 4MB Flash memory and 2MB PSRAM Castellated module and onboard ceramic antenna, allows soldering direct to carrier boards Supports flexible clock, module power supply independent setting, and other controls to realize low power consumption in different scenarios Integrated with USB serial port full-speed controller, 24 x GPIO pins allows flexibly configuring pin functions 4 x SPI, 2 x I2C, 3 x UART, 2 x I2S, 2 x ADC, etc. Support C/C++, MicroPython,Comprehensive SDK, Dev Resources, Tutorials To Help You Easily Get Started---Online Development Resource/Online Tutorials are provided: bit.ly/3Rdzxyr Hardware Connection Press the BOOT (GPIO0) key before connecting the Type-C cable each time download the firmware.
