Hi,
I am designing a board that I would call an espBee for lack of a better name. It will plug directly into the same headers that an xBee would plug into for serial communication with an atmega328, and use the same +3.3v, gnd, RX and TX pins. My question is what would be the absolute minimum pins and components that would be required.
Here are my thoughts: (this is for a pre-programmed esp-12e)
Arduino <---------> ESP-12E
+5v ---------------- +3.3v
Gnd ------------------ Gnd
RX --------------------- TX
TX -------------------- RX (with Voltage divider)
------------------------ CH_PD to 3.3v
Are any other connections required? Remember that this will be pre-programmed on a separate programming board.
Thanks for any comments!
