The ESP32-WROOM-32U module
(Datasheet)
is an alternative to the ESP32-WROOM-32D module with a uFL
connector for an external antenna instead of a PCBPrinted Circuit Board antenna. Both modules use the
ESP32-D0WD chip and have the same functionality, but they have different form factors.
The ESP32-WROOM-32D module size is 25.5mm x 18mm(1.00in x 0.71in), whereas the ESP32-WROOM-32U module has
a smaller footprint of 19.2mm x 18mm(0.76in x 0.71in).
The ESP32-WROOM-32UE module
(Datasheet)
is an alternative to the ESP32-WROOM-32E module with a uFL connector for an external
antenna instead of a PCB antenna. Both modules use either the ESP32-D0WD-V3 or
ESP32-D0WDR2-V3 chip and have the same functionality, but they have different form
factors. The ESP32-WROOM-32E module size is 25.5mm x 18mm(1.00in x 0.71in), whereas the ESP32-WROOM-32UE module has
a smaller footprint of 19.2mm x 18mm(0.76in x 0.71in).
The ESP32-D0WD, ESP32-D0WD-V3, and ESP32-D0WDR2-V3 SoCs by Espressif are part of the ESP32 series chips
(Datasheet)
that integrates an Xtensa 32-bit LX6 Dual-CoreMCUMicrocontroller 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
SoC and SPI flash chip.
