Description

The Espressif ESP32-WROOM-32 module (Datasheet) combines 2.4GHz WiFi (802.11IEEE 802.11 is a set of protocol standards that define communication for a Wireless Local Area Network (WLAN). In order for WiFi to work between different devices, they all need to agree on how they are going to communicate. The current version of the standard is IEEE 802.11-2007, with many amendments such as 802.11a, 802.11b, 802.11g, and 802.11n.b/g/n) and Bluetooth (v4.2 BRBasic Rate/EDREnhanced Data Rate and BLEBluetooth Low Energy) for a wide range of applications, from low power IoTInternet Of Things sensors to more demanding task such as voice encoding, music streaming and MP3Moving Picture Experts Group Layer-3 Audio (MP3) is a coding format for digital audio that uses lossy compression to reduce the overall file size.MP3 files are audio files used for storing and transferring music on computers, smartphones, online, and portable MP3 players. decoding. The ESP32-WROOM-32 module contains an ESP32-D0WDQ6 SoCSystem On a Chip, 4MB/8MB/16MB SPISerial Peripheral Interface Flash memory chip, 40MHz Crystal Oscillator, PCBPrinted Circuit Board Antenna, and some discrete passive components, all on the same board with a size of 25.5mm x 18mm (1.00in x 0.71in). The module has supply voltage range is between 3.0V and 3.6V and the max I/O logic voltage level is 3.3V.

The ESP32-D0WDQ6 SoC by Espressif is part of the ESP32 series chips (Datasheet) that integrates an Xtensa 32-bit LX6 Dual-Core MCUMicrocontroller Unit with a clock frequency up to 240MHz, RF circuitry for WiFi and Bluetooth, cryptographic hardware acceleration, RTCReal-Time Clock, and power management. Communication interfaces include UARTUniversal Asynchronous Receiver-Transmitter, I2CInter-Integrated Circuit. Also referred to as IIC or I2C., SPISerial Peripheral Interface, I2SInter-IC Sound, SDIOSecure Digital Input Output (SDIO) is a communication interface that allows devices to connect to an SD card and exchange data., CANController Area Network (CAN) is a high-integrity serial communication bus designed for harsh environments such as industrial and automotive applications., RMTRemote Control Transceiver (RMT) is a peripheral in ESP32 chips that was designed to act as an infrared transceiver that can generate precise timing pulses on a GPIO pin. Due to the flexibility of its data format, RMT can be extended to a versatile and general-purpose transceiver, transmitting or receiving many other types of signals., and ETHEthernet (Ethernet requires external physical interface device to connect to physical LANLocal Area Network bus). Peripheral interfaces include GPIOGeneral Purpose Input Output, PWMPulse-Width Modulation, Capacitive Touch inputs, 12-bit ADCAnalog-to-Digital Converter (ADC, A/D, or A-to-D), and 8-bit DACDigital-to-Analog Converter (DAC, D/A, or D-to-A). The ESP32-WROOM-32 module has a total of 38 contellated pins running along the edges of the board (14 pins on each of the long side edges and 10 pins on bottom short edge) to interface to the ESP32-D0WDQ6 SoC and SPI flash chip.

This module was originally named "ESP-WROOM-32", so you may see some older modules on the market with this label. Some vendors list the module with a "-N4", "-N8", or "-N16" at the end of the name to indicate the memory capacity (in MB) of the SPI Flash chip inside the module. For example, the ESP32-WROOM-32-N4 has 4MB, ESP32-WROOM-32-N8 has 8MB, and ESP32-WROOM-32-N16 has 16MB of SPI flash memory.

The ESP32-WROOM-32D is a revision of the ESP-WROOM-32 module which uses a ESP32-D0WD chip with a smaller footprint instead of an ESP32-D0WDQ6 chip. The ESP32-WROOM-32D module has the same functionality as the ESP32-WROOM-32, with both having the same size and are pin compatible.

The ESP32-WROOM-32E module is a direct upgrade to the ESP32-WROOM-32D that fixes some bugs with a new chip version ESP32-D0WD-V3 or ESP32-D0WDR2-V3. More details on the changes can be found in the ESP32 Chip Revision V3.0 User Guide (PDF). The ESP32-WROOM-32E module has the same functionality and form factor (25.5mm x 18mm) as the ESP32-WROOM-32D and ESP32-WROOM-32 modules, but the pins GPIO6 to GPIO11 of the V3 chip are not led out to the pins of the ESP32-WROOM-32E module on the bottom of the board. The impact of the pin change is that one cannot connect an external PSRAMPseudo Static Random Access Memory (PSRAM) is dynamic RAM with built-in refresh and address-control circuitry to make it behave similarly to Static RAM (SRAM). to the ESP32-WROOM-32E module.
