The ESP32-S3FH4R2 is a highly-integrated, low-power, 2.4 GHz Wi-Fi System-on-Chip (SoC) solution that now has WiFi and support, built-in native USB as as some other interesting new technologies like Time of Flight distance measurements. With state-of-the-art power and RF performance, this SoC is an ideal choice for a wide of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes.With native USB and 4MB Flash this board will let you upgrade your existing ESP32 projects. Native USB means it can like a keyboard or a disk drive, and no external USB-to-Serial converter required. WiFi and mean it's for IoT projects.ESP32-S3FH4R2 Dual Core 240MHz Tensilica processor - generation of ESP32-, with native USB so it can like a keyboard/mouse, MIDI device, disk drive, etc a reset button (great for restarting your or entering the bootloader), and a button on GPIO 0 for entering the bootloader or for inputThis chip is a great from the earlier ESP32-S2 This ESP32-S3 chip we are using with 4 MB flash and 2M PSRAM, it does have 512KB of SRAM,Supports CircuitPython, ESP-IDF and for FeaturesESP32-S3FH4R2 Dual Core 240MHz Tensilica processorType-C USB4MB Flash2M PSRAM13x IO1x1.0-4P connector(GND,3V3,SDA(GPIO2),SCL(GPIO1))1x RGB(GPIO39)1xLED(3.3V Power Supply)1xReset button(great for restarting your or entering the bootloader)1xBoot button(GPIO0,entering the bootloader or for input)Compatible with for MicroPython, for and ESP-IDF3.3V Regulator with 500mA outputCeramic AntennaSize: 23.5 x 18 mmWeight: 2.6gDOCUMENTShttps://github./01Space/ESP32-S3-0.42OLEDMaterial: PCBcolour: black Package Contents:1 x ESP32 S3 Development BoardOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing.
