The ESP-32F is a versatile WiFi-BT-BLE MCU module, powerful and versatile for use in low-power sensor networks and demanding tasks such as voice encoding, audio streaming and MP3 decoding. This module is the core ESP32 chip, with scalable, adaptive features. Two CPU cores can be individually controlled or powered on. The clock frequency can be adjusted from 80 MHz to 240 MHz. The user can cut off the power of the CPU and use low-power coprocessors to constantly monitor the state of the changes of peripheral or monitor whether certain analog values exceed the threshold. ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, low-noise sense amplifiers, SD card interface, Ethernet interface, high-speed SDIO, SPI, UART, I2S and I2C. 32-bit LX6 single / dual core processor with up to 600 DMIPS of computing power448 KB ROM,520 KB SRAM,16 KB SRAM in the RTC,QSPI can connect up to 4 Flash / SRAM, each flash is up to 16 MB Specification:CPU:Xtensaandreg; 32-bit LX6 single / dual-core processor with computing power up to 600 DMIPS;448 KB ROM; 520 KB SRAM; RTC 16 KB SRAM;QSPI can connect up to 4 Flash / SRAMs, up to 16 MB per FlashSupply voltage: 2.2V to 3.6VOperating current: average 80 mATemperature range: -40 ° C to + 85 ° C Clock and timer:Built-in 8 MHz oscillator, support self-calibrationBuilt-in RC oscillator, support self-calibrationSupports external 2 MHz to 40 MHz crystalSupports external 32 kHz crystal for RTC, supports self-calibration2 timer groups, each consisting of 2 pieces 64-bit general-purpose timers and 1 master system watchdogA RTC timer with sub-second precisionRTC watchdogPeripheral interface:12-bit SAR ADC up to 18 channels2 * 8-bit D / A converters10* touch sensors4 * SPIs2 * I2S2 * I2C3 * UARTs1 * Host SD / eMMC / SDIO1 * Slave SDIO / SPIEthernet MAC interface with dedicated DMA to support IEEE 1588CAN 2.0IR (TX / RX),motor PWM, LED PWM, up to 16 channels,Hall sensorUltra Low Noise Front Analog AmplifierPacking List:1 * ESP-32F Development Board1 * Transfer Board2 * Pin Headers
