ESP32C3 SuperMini is an IoT mini development board based on the ESP32C3 WiFi/Bluetooth dual mode chip. The ESP32C3 is a 32bit RISCV CPU with a floating point unit (FPU) that supports 32bit single precision operations, delivering capable on board computing for a compact form factor. Key benefits Powerful yet compact MCU: 32bit RISCV CPU with FPU provides solid processing power for edge tasks, data processing, and lightweight AI workloads. Dual mode wireless connectivity: supports IEEE 802.11 b/g WiFi and Bluetooth 5 (LE) for versatile wireless integration. Enhanced wireless range: external antenna included to improve signal strength and reliability for wireless applications. Rich and flexible I/O: 11 digital I/Os (PWM capable) and 4 analog I/Os (ADC capable) enable broad sensor and actuator integration. Flexible serial interfaces: four serial interfaces available for various peripherals (UART, I2C, SPI and I2S), facilitating easy connection to sensors, memories, and peripherals. Easy flashing and reset: built in reset button and boot loader mode button support quick development cycles. Specifications and design Brand/model: ESP32C3 SuperMini IoT mini development board Core processor: ESP32C3, 32bit RISCV with FPU Wireless: IEEE 802.11 b/g WiFi; Bluetooth 5 (LE) Antenna: external antenna to boost wireless performance I/O: 11 digital I/Os (PWM capable); 4 analog I/Os (ADC capable) Serial interfaces: UART, I2C, SPI and I2S Controls: reset button; boot loader mode button Mounting: compact single mount design Use scenarios Smart home device: acts as a wireless sensor hub or controller, collecting data from sensors via ADC and communicating over WiFi or Bluetooth. Prototyping and small IoT projects: flexible I/O and multiple serial interfaces support rapid integration of sensors, memory, and peripherals for proofofconcept devices. Edge processing node: on board computation with the ESP32C3 enables local data processing and communication in a small, lowpower package. Why this board stands out It combines a capable 32bit RISCV core with a robust dual wireless stack in a compact form factor, making it suitable for spaceconstrained IoT applications. The combination of an external antenna and multiple serial interfaces expands the range and flexibility for practical deployments. The escape hatch for development and flashing (reset and boot loader buttons) simplifies iterative testing and firmware updates. A clear balance of performance, connectivity, and I/O flexibility helps reduce design time for prototypes and smallscale productions.
