Espressif Systems ESP-WROOM-02D (4MB)

Mounting Type

Surface Mount

Package / Case

18-SMD Module

Operating Temperature

The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

-40°C~85°C

Packaging

Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.

Tape & Reel (TR)

Series

ESP

Part Status

Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.

Active

Moisture Sensitivity Level (MSL)

3 (168 Hours)

Voltage - Supply

2.7V~3.6V

Frequency

2.4GHz~2.5GHz

Memory Size

The memory capacity is the amount of data a device can store at any given time in its memory.

4MB Flash 50kB RAM

Data Rate

Data Rate is defined as the amount of data transmitted during a specified time period over a network. It is the speed at which data is transferred from one device to another or between a peripheral device and the computer. It is generally measured in Mega bits per second(Mbps) or Mega bytes per second(MBps).

72.2Mbps

Utilized IC / Part

ESP8266EX

Protocol

802.11b/g/n

Power - Output

20.5dBm

RF Family/Standard

WiFi

Antenna Type

There are several different types of antennas in three broad categories: omni-directional, directional, and semi-directional.

Integrated, Trace

Sensitivity

-98dBm

Serial Interfaces

A serial interface is a communication interface between two digital systems that transmits data as a series of voltage pulses down a wire. Essentially, the serial interface encodes the bits of a binary number by their "temporal" location on a wire rather than their "spatial" location within a set of wires.

ADC, GPIO, I2C, I2S, SPI, PWM, UART

Current - Receiving

50mA~56mA

Current - Transmitting

120mA~170mA

Modulation

64-QAM, BPSK, CCK, OFDM

RoHS Status

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.

ROHS3 Compliant
