This article covers Type-C Supermini ESP32-S3 開発ボード Supermini 開発ボード 2.4GHz WiFi Bluetooth 160MHz 動作周波数 Arduino対応 5個。.

Overview

The ACEIRMC Type-C Supermini ESP32-S3 Development Board is a thumb-sized (22.52×18mm) Arduino-compatible board powered by Espressif's ESP32-S3 chip. Its single-core 32-bit RISC-V processor runs at up to 160MHz, with built-in 2.4GHz WiFi (802.11b/g/n) and Bluetooth 5.0 connectivity. The board packs 400KB SRAM, 384KB ROM, and 4MB flash memory, making it ideal for compact IoT sensors and wearable projects. This 5-pack bundle offers excellent value for prototyping multiple nodes, classroom use, or experimenter workshops. Ultra-low power design draws approximately 43μA in deep sleep, enabling long battery life in wireless sensor networks. The USB Type-C connector handles both power and programming, ensuring seamless compatibility with modern laptops and PCs.

Connectivity & Compatibility

The board provides 1×I2C, 1×SPI, 2×UART, 11×GPIO (PWM-capable), and 4×ADC channels. An onboard RGB LED and blue LED (on GPIO48) are included for status indication. WiFi supports Station, SoftAP, and SoftAP+Station hybrid modes. The board works with Arduino IDE, PlatformIO, and other common development environments. Note that the GPIO count is limited compared to full-size ESP32 development boards, so it's not suitable for large-scale projects requiring many peripherals simultaneously. There is no external antenna connector; only the PCB trace antenna is fitted.

Product Info

The product is available on in a 5-pack configuration. The current price is 7,673 JPY (incl. tax, as of June 2026). Manufacturer is ACEIRMC. No official warranty period is stated; 's return policy applies. Market positioning: This is an entry-to-mid-range IoT development board. Its key strengths are ultra-compact size, low power consumption, and cost-effective multipack. It suits beginners learning embedded development and early-stage prototypes. For advanced projects requiring more GPIOs or higher processing power, larger boards would be needed.

Best Use Cases

IoT prototyping for makers and startups: Built-in WiFi and Bluetooth in a tiny footprint make this board perfect for smart home devices, environmental sensors, and mesh network nodes. Simple power requirements allow quick deployment of proof-of-concept hardware. Educational environments and hobbyists: Arduino IDE support lowers the learning curve. The 5-pack enables group activities or parallel experimentation in maker spaces and classrooms. Type-C connectivity ensures easy hookup with modern laptops. * Wearable and compact device design: The 22.52×18mm form factor fits easily into bracelets, badges, and compact gadgets. Deep-sleep current of 43μA maximizes battery life for always-on wearable sensors.
