      Note: The difference between T7 V1.4 changed to V1.5:   GPIO has replaced the position, we replaced GPIO16 and GPIO17 two pins that can no longer be used for external expansion with GPIO25 and GPIO27 that can be used with defined functions, so that they can be compatible with those of miniD1 The expansion board is not affected by the original GPIO16 and GPIO17 pins.   Hardware Specifications Chipset ESPRESSIF-WROVER-B 240MHz Xtensa® single-/dual-core 32-bit LX6 microprocessor FLASH QSPI flash 4MB 16MB / PSRAM  8MB SRAM 520 kB SRAM Button reset Modular interface UART、SPI、SDIO、I2C、LED PWM、TV PWM、I2S、IRGPIO、ADC、DACLNA  pre-amplifier On-board clock 40MHz crystal oscillator Working voltage 2.7V-3.6V Working current about 30mA
