It uses the ESP32-S3FH4R2 with an Xtensa® 32-bit LX7 dual-core processor running at up to 240MHz, while providing 2.4GHz Wi-Fi (802.11 b\/g\/n) and Bluetooth 5 (LE) for reliable wireless connectivity.\u003c\/p\u003e\n\u003cp\u003eThe board comes with 512KB SRAM, 384KB ROM, 4MB Flash memory, and 2MB PSRAM, giving developers a practical combination of processing power and memory for connected applications. Its compact castellated design and onboard ceramic antenna allow the ESP32-S3-Zero to be soldered directly onto a custom carrier board or PCB.\u003c\/p\u003e\n\u003cp\u003eFor hardware expansion, it provides 24 configurable GPIO pins, 4 × SPI, 2 × I2C, 3 × UART, 2 × I2S, and 2 × ADC interfaces. A USB Type-C port supports firmware programming and debugging, while the onboard WS2812 RGB LED, BOOT button, RESET button, and ME6217C33M5G 800mA maximum LDO add useful development features. The board also supports multiple low-power operating modes, making it suitable for battery-powered and always-connected applications.\u003c\/p\u003e\n\u003ch2\u003eFeatures:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003ePowered by a high-performance Xtensa® 32-bit LX7 dual-core CPU that can run at up to 240MHz.\u003c\/li\u003e\n\u003cli\u003eSupports Bluetooth® 5 (LE) and 2.4GHz Wi-Fi (802.11 b\/g\/n).\u003c\/li\u003e\n\u003cli\u003eBuilt-in 512KB SRAM and 384KB ROM, as well as stacked 4MB Flash and 2MB PSRAM.\u003c\/li\u003e\n\u003cli\u003eUses a castellated module (stamp hole) design with an integrated ceramic antenna for easy integration into user-designed baseboards.\u003c\/li\u003e\n\u003cli\u003eSupports configurable clock settings, separate module power supply control, and other characteristics for achieving multi-scenario low-power modes.\u003c\/li\u003e\n\u003cli\u003eThe integrated USB serial full-speed controller provides 24 GPIOs for versatile peripheral design.\u003c\/li\u003e\n\u003cli\u003eThe device includes 4 x SPI, 2 x I2C, 3 x UART, 2 x I2S, 2 x ADC, and more peripherals.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePinout Diagram:\u003c\/h2\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0559\/1970\/6265\/files\/Blog_images_1_-_2026-08-26T130423.264.png?v=1787730121\" alt=\"Waveshare ESP32-S3-Zero Development Board Pinout Diagram\" style=\"float: none;\"\u003e\u003c\/div\u003e","brand":"Waveshare","offers":[{"title":"Default Title","offer_id":54460076327136,"sku":"TIFDC0111","price":599.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0559\/1970\/6265\/files\/Waveshare_ESP32-S3-Zero_Development_Board_240MHz_with_2.4GHz_Wi-Fi_Bluetooth_5.png?v=1787729987","url":"https:\/\/robocraze.com\/products\/waveshare-esp32-s3-zero-development-board-240mhz","provider":"Robocraze","version":"1.0","type":"link"}
