The ESP32-S3FH4R2 is a highly-integrated, low-power, 2.4 GHz Wi-Fi System-on-Chip (SoC) solution that now has WiFi and BLE support, built-in native USB as well as some other interesting technologies like Time of Flight distance measurements. With its state-of-the-art power and performance, this SoC is an ideal choice for a wide variety of application scenarios relating to the Internet of Things (IoT), wearable electronics, and smart homes. With native USB and 4MB Flash this board let you upgrade your existing ESP32 projects. Native USB means it can act like a keyboard or a disk drive, and no external USB-to-Serial converter required. WiFi and BLE mean it's awesome for IoT projects. ESP32-S3FH4R2 Dual Core 240MHz Tensilica processor - generation of ESP32-Sx, with native USB so it can act like a keyboard/mouse, MIDI device, disk drive, etc! a reset button (great for restarting your program or entering the bootloader), and a button on GPIO 0 for entering the ROM bootloader or for user input This chip is a great step up from the earlier ESP32-S2! This ESP32-S3 chip we are using with 4 MB flash and 2M PSRAM, but it does have 512KB of ,Supports CircuitPython, ESP-IDF and for Features ESP32-S3FH4R2 Dual Core 240MHz Tensilica processor Type-C USB 4MB Flash2M PSRAM 13x IO 1x1.0-4P connector(GND,3V3,SDA(GPIO2),SCL(GPIO1)) 1x RGB(GPIO39) 1xLED(3.3V Power Supply) 1xReset button(great for restarting your program or entering the bootloader) 1xBoot button(GPIO0,entering the ROM bootloader or for user input) Compatible with for MicroPython, for and ESP-IDF 3.3V Regulator with 500mA output Ceramic Antenna Size: 23.5 x 18 mm Weight: 7.8g Material: PCB colour: black Package Contents: 3 x ESP32 S3 Development Board Only the above package content, other products are not included.
