Frequently asked questions
How do I connect the module to my microcontroller?
Connect the module's serial TX and RX to the RX and TX of your microcontroller, cross the lines, and share a common GND. Follow the ESP-Link documentation for the exact pins and baud rate.
Can I replace ESP-Link with my own firmware?
Yes, the ESP8266 can be reflashed with other firmware, but this removes ESP-Link. Keep a backup of the original firmware if you plan to restore it later.
