Product description: NULA DeepSleep ESP32-S3 - WiFi + Bluetooth development board - without connectors - Soldered 333352
The NULA DeepSleep ESP32-S3 is a modern development board designed for building energy-efficient IoT devices, telemetry systems, and intelligent wireless sensors. At the heart of the module is the ESP32-S3-WROOM-1-N8R8 chip with a dual-core Xtensa LX7 processor clocked at up to 240 MHz, supported by 8 MB of Flash memory and 8 MB of PSRAM . The board provides 2.4 GHz WiFi and Bluetooth 5 LE communication, enabling the development of advanced wireless applications. Onboard is the PCF85063A RTC chip responsible for precise timekeeping during sleep mode, and a TP4056M charger supporting Li-Ion and Li-Po batteries. The design has been optimized for very low power consumption – in deep sleep mode, the board draws approximately 7 µA . Compatibility with Arduino IDE, ESP-IDF, and MicroPython makes getting started quick and convenient for both beginners and advanced users.

The NULA DeepSleep ESP32-S3 is perfect for projects requiring very low power consumption and wireless communication.

ESP32-S3 pins and communication interfaces
The NULA DeepSleep ESP32-S3 board features 22 GPIO pins for a variety of communication interfaces and peripheral functions. These include two SPI, three UART, two I2C, and two I2S interfaces , allowing the module to interface with displays, sensors, radio modules, and external memories. The board also includes 12-bit ADC inputs, PWM outputs, touch functions, and RTC lines for waking from deep sleep mode. An integrated connector The Qwiic / easyC / STEMMA QT allows you to quickly connect compatible I2C modules without the need for soldering wires. A USB Type-C connector is used for power and programming, while a Li-Ion or Li-Po battery can be connected via a JST connector. The board also has a hardware RESET button and the ability to disconnect the WS2812B LED via jumper JP1 to reduce power consumption.
NULA DeepSleep ESP32-S Programming
The board is fully compatible with the Arduino IDE, ESP-IDF, and MicroPython environments, making it suitable for both simple educational projects and professional embedded applications. The official Espressif Arduino Core package includes a ready-made board definition, significantly simplifying programming environment setup. Programming is performed directly via the native USB port on the USB Type-C connector , eliminating the need for additional UART converters. The module also supports USB Serial/JTAG and HID interfaces, expanding the possibilities of creating devices that communicate with a computer. MicroPython support allows you to quickly create and test Python applications. Advanced developers can use the ESP-IDF framework, which offers full access to the ESP32-S3's features, including security mechanisms such as Secure Boot and Flash memory encryption.
