Specification AudioOutputMode : Stereo, Surround Brand : Zendstanding BulletPoint1 : 2.4GHz Dual Mode WiFi+Bluetooth Development Board: Built in ESP32-S2 chip, Xtensa single core 32-bit LX7 microprocessor, supporting clock frequencies up to 240 MHz. 128 KB ROM, 320 KB SRAM, 16 KB RTC SRAM. The chip supports secondary development without the need for other microcontrollers or processors BulletPoint2 : Compatible With Arduino+LoRa: The ESP32 development board is 100% compatible with the Arduino IDE, Lua, and Micropython. It is easy to develop and supports the LWIP protocol, Freertos, and three modes: AP, STA, and AP+STA BulletPoint3 : Advanced Peripheral Interfaces & Sensors: SPI, I2S, UART, I2C, LED PWM, LCD interface, Camera interface, ADC, DAC, touch sensor, temperature sensor, and up to 43 GPIOs. In addition, this series of chips also includes a full-speed USB On The Go (OTG) interface, which can support USB communication BulletPoint4 : Ultra Low Power Coprocessor (ULP): ESP32-S2 series chips support multiple low-power operating states, and ULP low-power coprocessors can operate in ultra-low power states, meeting the requirements of power consumption requirements for various application scenarios. The precise clock gating, dynamic voltage clock frequency adjustment, and adjustable output power of RF power amplifiers unique to chips can balance communication distance, data rate, and power consumption best BulletPoint5 : Unique Hardware Security Mechanism: The hardware encryption accelerator supports AES, SHA, and RSA algorithms. RNG, HMAC, and Digital Signature modules provide more security performance. Other security features include flash encryption and secure boot signature verification. A comprehensive security mechanism enables the chip to meet strict security requirements BulletPoint6 : 1、You Can Get: 3PCS ESP32 ESP-32S ESP-WROOM-32 Development Board Kits 2、ESP32-S2 Series Chip Technology Electronic Version Specification Sheet 3、Our Lifetime Warranty, After-Sales Service, And Unconditional Free Replacement With A Brand New One Within 1 Year Color : Black+ Silvery CompatibleDevices : Arudino IDE, Lua and Micropython ConnectivityTechnology : GPIO ConnectivityTechnology1 : Interface USB TYPE-C ConnectivityTechnology2 : Wireless WiFi Bluetooth ConnectorType : 3.5mm Jack ControlMethod : remote ControlMethod1 : remote ControlMethod2 : application ExternallyAssignedProductIdentifier : 4673724090020 ExternallyAssignedProductIdentifier1 : 682559865943 ExternallyAssignedProductIdentifier2 : 0682559865943 IncludedComponents : IR Receiver Sensor IncludedComponents1 : ESP32 *1 IncludedComponents2 : ESP-32S *1 IncludedComponents3 : ESP-WROOM-32 *1 ItemName : ESP32 ESP-32S ESP-WROOM-32 Development Board Kits 2.4GHZ Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor USB Type-C Interface Compatible with Arduino IDE NodeMCU, 3PCS ItemPackageDimensions_Height : 16.891 centimeters ItemPackageDimensions_Length : 1.7018 centimeters ItemPackageDimensions_Width : 9.6012 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : single-board-computers Manufacturer : Zendstanding MemoryStorageCapacity : 128 KB ModelName : ESP32 ESP-32S ESP-WROOM-32 ModelNumber : KB053 NumberOfItems : 1 OperatingSystem : Linux-based operating system PartNumber : KB053 ProcessorCount : 2 ProductDescription : ESP32 ESP-32S ESP-WROOM-32 Development Board Kits 2.4GHZ Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor USB Type-C Interface Compatible with Arduino IDE, 3PCS ProductSiteLaunchDate : 2024-06-03T07:00:00.000Z Size : 3PCS-ESP32 SupplierDeclaredDgHzRegulation : not_applicable SupplierDeclaredHasProductIdentifierExemption : 1 SurroundSoundChannelConfiguration : 5.1 TotalUsbPorts : 1 UnspscCode : 43201500 WarrantyDescription : Manufacturer warranty for 2 years from date of purchase WirelessCommStandard : radio_frequency WirelessCommStandard1 : 802_11_ABGN WirelessCommStandard2 : 2.4_ghz_radio_frequency WirelessCommStandard3 : bluetooth WirelessCommunicationTechnology : IR
