In Stock
The ESP32C3 SuperMini V2.0 Red Board is a highly compact development board based on the ESP32C3 RISCV singlecore processor, running at up to 160 MHz [citation:2][citation:5][citation:8]. It provides WiFi 4 and Bluetooth 5.0 (LE) in a tiny 22.52 x 18mm form factor, making it perfect for spaceconstrained IoT and wearable projects [citation:1][citation:8].

= Key Features =
UltraCompact Fits into tight enclosures and wearables
USBC Native Programming No external adapter needed, supports CDC for serial output [citation:5][citation:7]
Onboard Dual LEDs - Blue LED (GPIO8) and RGB NeoPixel (WS2812B) [citation:1]
Low Power Consumption - 43µA deep sleep ideal for battery projects [citation:2][citation:8]
External Antenna Support IPEX connector for enhanced WiFi/BT range [citation:5]
Strapping Pin Management - GPIO8, GPIO9, and GPIO2 control boot modes [citation:11]
√ Compatible with Arduino IDE, ESP-IDF, and MicroPython [citation:5][citation:10]
√ Onboard buttons for RESET and BOOT (GPIO9) for easy firmware upload [citation:10]
√ Breadboard-friendly with 2.54mm pin pitch [citation:5]
The board uses a shared GPIO8 for both the blue status LED and the RGB NeoPixel [citation:1][citation:11]. This shared configuration requires careful handling to avoid conflicts between PWM control for the blue LED and the timing-critical NeoPixel data stream [citation:1].
