Berikut adalah referensi pinout ESP8266 NodeMcu yang baik digunakan dalam beberapa project, saya biasanya sebelumnya memilih untuk menggunakan pin-pin berikut :
| Label | GPIO | Input | Output | Notes |
|---|---|---|---|---|
| D0 | GPIO16 | no interrupt | no PWM or I2C support | HIGH at boot used to wake up from deep sleep |
| D1 | GPIO5 | OK | OK | often used as SCL (I2C) |
| D2 | GPIO4 | OK | OK | often used as SDA (I2C) |
| D3 | GPIO0 | pulled up | OK | connected to FLASH button, boot fails if pulled LOW |
| D4 | GPIO2 | pulled up | OK | HIGH at boot connected to on-board LED, boot fails if pulled LOW |
| D5 | GPIO14 | OK | OK | SPI (SCLK) |
| D6 | GPIO12 | OK | OK | SPI (MISO) |
| D7 | GPIO13 | OK | OK | SPI (MOSI) |
| D8 | GPIO15 | pulled to GND | OK | SPI (CS) Boot fails if pulled HIGH |
| RX | GPIO3 | OK | RX pin | HIGH at boot |
| TX | GPIO1 | TX pin | OK | HIGH at boot debug output at boot, boot fails if pulled LOW |
| A0 | ADC0 | Analog Input | X |
