Description
The WeAct Studio S3 Mini IoT Board is a feature-rich development platform centered on the Espressif ESP32-S3FH4R2 SoC. This chip delivers a dual-core Xtensa LX7 processor capable of running at up to 240 MHz, coupled with 4MB of flash memory and 2MB of PSRAM, providing ample resources for data-intensive IoT tasks and Over-the-Air (OTA) updates.
Its integrated 2.4 GHz Wi-Fi radio supports IEEE 802.11 b/g/n protocols, while the Bluetooth LE 5.0 stack enables low-power peripheral and mesh networking. The board’s 27 configurable GPIO pins expose a full suite of industrial interfaces, including 14-bit ADC, 8-bit DAC, multiple UARTs, SPI, I2C, and USB On-The-Go, allowing for seamless sensor integration and peripheral expansion. Power management is optimized for battery-operated scenarios, with support for deep sleep modes to minimize current consumption.
