M5Stack StampS3 BAT Module ESP32-S3 with 2.54mm Header

The M5Stack StampS3 BAT Module is a compact embedded-core module with integrated power management based on the ESP32-S3-PICO-1-N8R8 main controller. The Dual-Core Xtensa LX7 processor operates at a clock speed of up to 240 MHz and is complemented by 8 MB of Flash and 8 MB of PSRAM. For wireless communication, 2.4 GHz Wi-Fi is available. The module features 11 freely usable GPIOs and an additional Wake-up-IO, along with a 24-pin BTB connector supporting a DVP interface. An external 3.7V lithium battery can be connected via the integrated battery interface (SH1.0-2P). The multi-stage M5MP1 power management design enables control of input and output current, lithium battery charging, and monitoring of input and battery voltage. Additionally, an external low-power wake-up function is supported, allowing the module to be reactivated via the Wake-up-IO after entering sleep mode. A programmable RGB-LED (WS2812) is also included. The DIP variant comes with pre-soldered 2.54mm pin headers, allowing direct use on breadboards, PCB insertion, or connection via Dupont cables. Power supply options include the 3.7V battery, USB Type-C, or 5V DC.

Features:

• Powerful ESP32-S3 Dual-Core processor with up to 240 MHz clock speed enables demanding IoT applications.
• Integrated M5MP1 power management controls charging, input current, and voltage monitoring in multiple stages.
• Pre-soldered 2.54mm pin headers allow direct use on breadboards and PCBs.
• 11 GPIOs and a Wake-up-IO provide flexible connections for sensors and actuators.
• The 24-pin BTB connector supports a DVP camera interface with 19 additional GPIOs.
• Extremely low power consumption in sleep mode at just 13.43 µA at 4.2 V enables long battery life.

Application Examples:

• Battery-powered IoT sensor nodes for environmental monitoring or smart home applications.
• Camera-based projects via the DVP interface of the BTB connector.
• Rapid prototyping on breadboards for Wi-Fi-enabled embedded systems.
• Portable data loggers with low-power wake-up functionality.
