1. Module introduction
1.1 Feature introduction
Figure 1 Actual picture of the module
ESP32-S3-WROOM-1-TB & ESP32-S3-WROOM-1U-TB are two entry-level development boards equipped
with Wi-Fi + Bluetooth® LE modules ESP32-S3-WROOM-1, ESP32-S3-WROOM-1U . This development board
has complete Wi-Fi and low-power Bluetooth functions , and most of the pins of the modules on the board have been
led to pin headers on both sides. Developers can easily connect various peripherals through jumpers according to
actual needs. equipment, and the development board can also be used on a breadboard.

ESP32-S3-WROOM-1 &
ESP32-S3-WROOM-1 U
ESP32-S3-WROOM-1, ESP32-S3-WROOM-1U and
ESP32-S3-WROOM-2 are general-purpose Wi-Fi + Bluetooth
low-power MCU modules with rich peripheral interfaces and powerful
neural network operations capabilities and signal processing
capabilities, specifically built for the artificial intelligence and AIoT
markets. ESP32-S3-WROOM-1 and ESP32-S3-WROOM-2 use PCB
on-board antennas, and ESP32-S3-WROOM-1U uses a connector to
connect to an external antenna.

5 V to 3.3 V LDO
Power converter, input 5 V, output 3.3 V.
3
Pin
All available GPIO pins (except the SPI bus of the flash) have been led
out to the pin headers of the development board. Please see Pin Headers
for more information.
4
USB to UART interface
The Micro-USB interface can be used as the power supply interface of
the development board, can burn firmware to the chip, and can also be
used as a communication interface to communicate with the chip
through the onboard USB-to-UART bridge.
