PIN Description

PIN	DIRECTION	Description
USB Connector	I	The USB dongle is powered from the USB port (3.8V-5V)
LED1 (USER)	O	LED which can be controlled from MCU (D25). When the pin is

HIGH value, the LED is on, when the pin is LOW, it is off
LED2 (USER)| O| LED which can be controlled from MCU (D26). When the pin is HIGH value, the LED is on, when the pin is LOW, it is off
LED (NET)| O| Indicate the EG95 operation status
LED (STAT)| O| Indicate the EG95 network activity status
MCU RESET

User Button| I| Connected to digital pin, D0, of MCU and can be used for user- defined purposes
USB Switch| I| 1 switch to connect to MCU directly or EG95 directly

IOREF

| ****

O

| Provides the voltage reference with which the MCU operates. A device can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V

3.3V

| ****

O

| 3.3V generated by the on-board regulator. Maximum current drawn is 3A. The regulator also provides power to the MCU and EG95
5V| O| 5V generated from the board. The board is supplied with power from USB connector (typical 5V)
GND| | Ground
A0| IO| Six analog inputs which can provide up to 12 bits of resolution (i.e. 4096 different values). By default, each input measures from ground to 3.3 volts, though is it possible to change the upper end of their range using the AREF pin

A0 can also be used as a DAC output and provides a 10 bit voltage output with analo gWr it e () function
