ESP 01-ESP8266 MINI

Description

The ESP8266 ESP-01 is a serial to breakout module with a built in ARM microprocessor that has 1MB of memory and 2 GPIOs brought out to the header for connecting to peripherals.  It can be used as a serial bridge to add capability to a project or it can even be programmed directly and used as a little stand-alone processor.  It has full TCP/IP capability built-in.

PACKAGE INCLUDES:

• ESP8266 ESP-01 Module

KEY FEATURES OF ESP8266 ESP-01  MODULE:

• 32-bit RISC LX Processor running at 80MHz
• 1MB Flash Memory
• IEEE 802.11 b/g/n 2 GPIO
• 3.3V Operation

The module requires 3.3V for power and is not 5V tolerant on its pins.  If connecting to a 5V MCU, the RX pin of the ESP-01 module which is driven by the TX pin from the MCU should have a level shifter installed.  This can just be a simple voltage divider using 2 resistors as shown down below.  If you are using it with our ESP-01 adapter, the adapter includes level shifting as well as a 3.3V regulator, so it makes the ESP-01 module plug-n-play.

The module has a red power LED and a blue LED to indicate data flow.  The antenna is the meandering PCB trace that covers the end of the module.
