- I want to use the UART Wifi V2 with Arduino UNO with Base Shield V2. In the wiki it states that the input voltage is 3V / 5V, but from what I know ESP8266 / ESP8285 can only have max 3.3V. Is it safe for me to connect it directly to Arduino UNO via the Base Shield?
- The example code provided in the wiki uses a OLED. May I know how to use on the serial monitor instead?
