+### 🏆 The Best Choice: GPIO 4 and GPIO 5
124
+
125
+If they are available on your board (like the NodeMCU or WeMos D1 Mini), **GPIO 4 and GPIO 5 are the absolute best choices.**
126
+
127
+* **GPIO 5 (D1) ➔ RX**
128
+* **GPIO 4 (D2) ➔ TX**
129
+
130
+Why they are the best:
131
+
132
+These pins are completely "safe." They do not have any special pull-up or pull-down requirements during boot, meaning they won't interfere with the ESP8266 waking up, regardless of what external device you have hooked up to them.
133

135

136
+### 🥈 The Backup Choice: GPIO 12 and GPIO 13
137
+
138
+If you are already using GPIO 4 and 5 for something else (like I2C communication), your next best bet is this pair:
139
+
140
+* **GPIO 13 (D7) ➔ RX**
141
+* **GPIO 12 (D6) ➔ TX**
