The maximum input voltage of the ADC0 pin is 0 to 1V if you’re using the ESP8266 bare chip. If you’re using a development board like the ESP8266 12-E NodeMCU kit, the voltage input range is 0 to 3.3V because these boards contain an internal voltage divider. You can learn how t...
Pin12:MTCK is an input/output pin labeled as GPIO13 and it is used in SPI as Master-Out Slave-In pin (SPI_MOSI) as well as used in UART as Clear To Send pin (UART_CTS). Pin13:MTDO is an input/output pin labeled as GPIO15 and it is used in SPI as Chip Select pin (SPI_C...
NodeMCU is an open-source Lua based firmware anddevelopment boardspecially targeted for IoT based Applications. It includes firmware that runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. NodeMCU Development Board Pinout Configuration 特殊引脚情...
PinoutDimensionsQuick start Hardware connection Press and hold the BOOTSEL button of Pico, the pico will be recognized as a movable disk, copy the dev_cdc_ports.uf2 file from demo codes to the Pico, the Pico will automatically restart and work as the USB to serial adapter. Connect the ...
Here’s a simple ESP8266 pinout guide: VCC: Connect to 3.3V power supply GND: Connect to ground of the UART or Arduino TX: Connect to RX of the UART or Arduino RX: Connect to TX of the UART or Arduino (use a voltage divider to step down from 5V to 3.3V if using Arduino)...
