The M5Stack Stamp-S3Bat packs ESP32-S3 processing and Wi-Fi into a battery-ready module with built-in charging and smart power control. The M5Stack Stamp-S3Bat is an embedded core module with integrated power management. It uses the ESP32-S3-PICO-1-N8R8 as the main control core, supporting 2.4GHz Wi-Fi, with built-in 8MB Flash and 8MB PSRAM. The module leads out a total of 11 GPIOs and 1 wake-up IO, and is equipped with a 24P BTB connector (supporting DVP interface). The onboard battery power interface is used for external 3.7V lithium battery power supply. It features the built-in M5MP1 multi-level power control design, supporting power input/output control, lithium battery charging management, and status detection sucfgroh as input voltage and battery voltage. It also supports external low-power wake-up functions; after the main controller enters a low-power sleep state, the power can be restarted via the external wake-up IO. The module features an onboard programmable RGB LED and adopts a 2.54mm standard pitch half-hole pad design, supporting various integration methods such as SMT and DIP, making it convenient for developers to quickly build IoT applications. We also stock the M5StampS3 BAT Module with 2.54 Header Pin.
