I will try use WROOM-02 in my next project instead of ESP12E - and i have a question about I2C pins - from espressif wroom-02 datasheet I2C is on pins SCL-IO14, SDA-IO2 (ESP12E - SCL IO5 / SDA IO4) but i found some project isung wroom -02 and pins was like in ESP12E IO5 - IO4
I am using arduino for this.
