ESP32-C3 Development Board with 0.42" OLED Display (HW675)

ESP32-C3 Wi-Fi and Bluetooth LE development board with built-in 0.42-inch OLED screen and USB-C.

Prototype a compact IoT dashboard, sensor node, or wearable without wiring up a separate display. This HW675 board pairs an ESP32-C3 RISC-V microcontroller with a 0.42-inch OLED for onboard visual feedback, a USB Type-C programming and power port, and accessible GPIO connections along both edges. Reset and BOOT buttons make development convenient in a small footprint.

Key features

• ESP32-C3 RISC-V microcontroller with Wi-Fi and Bluetooth LE
• Integrated 0.42-inch OLED for status and data display
• USB Type-C port for programming and power
• Onboard Reset and BOOT buttons
• Dual-row GPIO breakout for prototyping
• Suited for IoT dashboards, sensor nodes, and wearable projects

Build note: Check the HW675 pinout and OLED interface before wiring peripherals or loading display code.
