Headers are not pre-soldered. Soldering is required for header connections.

Build compact wireless projects with the Seeed Studio XIAO ESP32-C3. Its 21 x 17.8 mm footprint makes it a useful starting point for small sensor nodes, connected controls and space-constrained prototypes.

Key specifications

• ESP32-C3 single-core, 32-bit RISC-V processor, up to 160 MHz
• 400 KB SRAM and 4 MB onboard flash
• 2.4 GHz 802.11b/g/n Wi-Fi and Bluetooth 5.0 LE
• 11 GPIO with PWM; I2C, SPI, UART and analog inputs
• USB-C connection for programming and power

Getting started

Use a data-capable USB-C cable and follow Seeed Studio's Arduino setup guide. For analog sensing, Seeed recommends A0-A2 (ADC1) rather than A3 (ADC2) for reliable readings.

Planning a project?

For a compact display-and-control interface, explore our Tiny 0.32-Inch OLED Display Module and Mini Rotary Encoder Breakout with Push Button. These are separate project components, not included accessories or a tested plug-and-play kit. Wiring, soldering and firmware setup are required.
