ESP-32F Module + Adapter Board WiFi bluetooth Dual Core CPU MCU IoT Geekcreit for Arduino – products that work with official Arduino boards

Description

Introduction: The ESP-32F is a universal WiFi-BT-BLE MCU module that is powerful and versatile for low-power sensor networks and demanding tasks such as voice coding, audio streaming and MP3 decoding.The core of this module is the ESP32 chip, which is scalable and adaptive. Two CPU cores can be individually controlled or powered up. The clock frequency can be adjusted from 80 MHz to 240 MHz. The user can power off the CPU and use a low-power coprocessor to constantly monitor the status changes of the peripherals or whether certain analogs exceed the threshold. The ESP32 also integrates a wide range of peripherals including capacitive touch sensors, Hall sensors, low noise sense amplifiers, SD card interfaces, Ethernet interfaces, high speed SDIO, SPI, UART, I2S and I2C.The ESP-32F integrates traditional bluetooth, bluetooth low energy and Wi-Fi for a wide range of uses: Wi-Fi supports a wide range of communication connections and direct Internet connection via a router; bluetooth allows users to connect to mobile phones or broadcast BLE Beacon for signal detection. The ESP32 chip's sleep current is less than 5 ?A, making it suitable for battery-powered wearable electronics. The ESP-32F supports data rates up to 150 Mbps and a power amplifier with an output power of 22 dBm for maximum wireless communication. As a result, the chip has industry-leading specifications and performs best in terms of high integration, wireless transmission distance, power consumption, and network connectivity.The ESP32's operating system is a freeRTOS with LWIP and TLS 1.2 with hardware acceleration. The chip also supports OTA encryption upgrades, and developers can continue to upgrade after the product is released. CPU: Xtensa® 32-bit LX6 single/dual-core processor with up to 600 DMIPS448 KB ROM520 KB SRAM16 KB SRAM in RTCQSPI can connect up to 4 Flash / SRAM, up to 16 MB per FlashSupply voltage: 2.2V to 3.6VWorking current: average: 80 mAPackage size: 18 mm x 25.5 mm x 2.8 mmTemperature range: -40°C ~ +85°C Clock and Timer: Built-in 8 MHz oscillator with self-calibrationBuilt-in RC oscillator for self-calibrationSupport for external 2 MHz to 40 MHz crystalSupports an external 32 kHz crystal for RTC with self-calibration2 timer groups, each consisting of 2 64-bit general-purpose timers and 1 main system watchdogRTC timer with sub-second precisionRTC watchdog Peripheral interface: 12-bit SAR ADC with up to 18 channels2 8-bit D/A converters10 touch sensorsTemperature Sensor4 SPI2 I2S2 I2C3 UARTs1 Host SD / eMMC / SDIO1 Slave SDIO / SPIEthernet MAC interface with dedicated DMA supporting IEEE 1588CAN 2.0IR (TX / RX)Motor PWMLED PWM, up to 16 channelsHall sensorUltra low noise preamplifier Wi-Fi: Standard: FCC/CE/IC/TELEC/KCC/SRRC/NCC Protocol: 802.11 b/g/n/d/e/i/k/r (802.11n, speeds up to 150 Mbps)A-PDU and A-MSDU aggregation, support 0.4 ?s guard interval Frequency Range: 2.4 ~ 2.5 GHz Wi-Fi mode: Station/softAP/SoftAP+station/P2P Security Mechanism: WPA/WPA2/WPA2-Enterprise/WPS Encryption type: AES/RSA/ECC/SHA bluetooth: Protocol: Compliant with bluetooth v4.2 BR/EDR and BLE standards RF: NZIF receiver with -98 dBm sensitivityClass-1, Class-2 and Class-3 transmittersAFH Audio: CVSD and SBC audio Package includes: 1 x ESP-32F module1 x Adapter plate2 x Pins
