ESP32-S3 Supermini Development Board WiFi Bluetooth 50 Ultra-Small Size ESP32 S3 ESP32-S3FH4R2 For Arduino For Micropython ESP32S3SuperMini is an IoT mini development board based on the Espressif ESP32-S3 WiFi/ Bluetooth dual-mode chip. The ESP32-S3 is a 32-bit RISC-V CPU that contains the FPU (floating point unit), which can perform 32-bit single-precision operations and has powerful computing power. It has excellent RF performance and supports IEEE 802.11b /g/n WiFi and Bluetooth 5 (LE) protocols. The board comes with an external antenna to enhance signal strength for wireless applications. It also has a small and delicate form factor combined with a single-sided surface mount design. It is equipped with a wealth of interfaces, with 11 digital I/ OS that can be used as PWM pins and 4 analog I/ OS that can be used as ADC pins. It supports four serial interfaces: UART, I2C and SPI. The board also has a small reset button and a boot loader mode button. _x000D_ Based on the above features, ESP32S3SuperMini is positioned as a high-performance, low-power and cost-effective iot mini development board suitable for low-power iot applications and wireless wearable applications. _x000D_ _x000D_ ESP32S3-SuperMini _x000D_ _x000D_ # Hardware description _x000D_ # _x000D_ Product parameter _x000D_ Powerful CPU: ESP32-S3, 32-bit RISC-V single-core processor, running at up to 160 MHz _x000D_ WiFi: 802.11b/g/n protocol, 2.4GhHz, support Station mode, SoftAP mode, SoftAP+Station mode, hybrid mode _x000D_ Bluetooth: Bluetooth 5.0 _x000D_ Ultra-low power consumption: deep sleep power consumption of about 43A _x000D_ Rich board resources: 400KB SRAM, 384KB ROM built-in 4Mflash. _x000D_ Chip model: ESP32S3FH4R2 _x000D_ Ultra-small size: As small as the thumb (22.52x18mm) classic shape, suitable for wearables and small projects _x000D_ Reliable security features: Encryption hardware accelerators that support AES-128/256, hashing, RSA, HMAC, digital signatures, and secure startup _x000D_ Rich interface: 1xI2C, 1xSPI, 2xUART, 11xGPIO(PWM), 4xADC _x000D_ Onboard RGB, blue LED: common GPIO48 pin _x000D_ # Pin diagram _x000D_ _x000D_ _x000D_ Ardunino ESP32S3 Dev Module Pin mapping _x000D_ # _x000D_ _x000D_ Dimension drawing _x000D_ _x000D_ # External power supply _x000D_ If external power supply is required, just connect the external power + level to the B+ position on the back of the board, and connect the negative pole to the B- on the back.
