Programming the ESP8266

Question

Hi,

Recently I have designed an ESP8266 board for a project. The PCB material is the roger board. Currently, i am facing difficulties to detect the board. For the communication, i am using the FTDI. The picture below is the PCB board. Appreciate the help from the members to help solve the issue.

Thank you.

Have you verified that all signals are connected to the correct pins with a continuity check?

Have you looked at and traced the serial signals from source to receiver with a scope?

Do you have test software/firmware that continuously tries to send signals both ways so you can see valid signal data on all connections and pins?
