Headers come pre-soldered facing down, and a USB cable is included, so it is ready for a breadboard out of the packet.\u003c\/p\u003e\n\n\u003ch2\u003eWhat N16R8 Actually Means\u003c\/h2\u003e\n\u003cp\u003eThe suffix is the memory configuration, and it is the main thing separating one ESP32-S3 board from another. \u003cstrong\u003eN16\u003c\/strong\u003e is 16MB of flash, which is where your program and any web assets live. \u003cstrong\u003eR8\u003c\/strong\u003e is 8MB of PSRAM, extra RAM the chip can use for buffers. That combination is the high-spec end of the range, and it is what you want if you are driving a display, buffering camera frames, serving a web interface, or running anything that outgrows the chip's internal memory. Cheaper boards ship as N4 or N8R2 and run out of room quickly on those jobs.\u003c\/p\u003e\n\n\u003ch2\u003eWhat Makers Build With It\u003c\/h2\u003e\n\u003cp\u003eThis is the board behind a lot of the enclosures and brackets people print:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrinter and drybox monitoring\u003c\/strong\u003e, reading temperature and humidity and reporting over WiFi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilament runout and jam sensors\u003c\/strong\u003e wired into a printer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAddressable LED control\u003c\/strong\u003e for chamber lighting and status displays\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHome automation nodes\u003c\/strong\u003e running ESPHome or Tasmota\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall displays and camera projects\u003c\/strong\u003e, which is where the 8MB of PSRAM earns its place\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTwo Type-C Ports and Automatic Download\u003c\/h2\u003e\n\u003cp\u003eThe board carries two USB Type-C ports rather than one, and supports automatic download. In practice that means you plug in, hit upload, and the board resets itself into bootloader mode without you holding BOOT and tapping RESET. If you have used an older ESP board and remembered the button dance, this is the part you will notice first.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip:\u003c\/strong\u003e Espressif ESP32-S3, dual-core Xtensa LX7 at up to 240MHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlash:\u003c\/strong\u003e 16MB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePSRAM:\u003c\/strong\u003e 8MB\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiFi:\u003c\/strong\u003e 802.11 b\/g\/n, 2.4GHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBluetooth:\u003c\/strong\u003e Bluetooth 5.0 and Bluetooth Low Energy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeaders:\u003c\/strong\u003e 44-pin, pre-soldered facing down\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGPIO:\u003c\/strong\u003e up to 38 usable pins on the ESP32-S3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUSB:\u003c\/strong\u003e two Type-C ports, automatic download supported\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput voltage:\u003c\/strong\u003e 3.0V to 5V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOnboard:\u003c\/strong\u003e RGB LED, Boot and Reset buttons\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 34.8g\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e USB cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eGetting Started\u003c\/h2\u003e\n\u003cp\u003eThe board works with the usual ESP32 toolchains: \u003cstrong\u003eArduino IDE\u003c\/strong\u003e, \u003cstrong\u003eESP-IDF\u003c\/strong\u003e and \u003cstrong\u003ePlatformIO\u003c\/strong\u003e.
