Overview

Product Overview

Pre-soldered XIAO ESP32C3 Microcontroller with WiFi and BLE offers a compact, ready-to-use platform for embedded and IoT projects. Pre-soldered for immediate prototyping and a small form factor (20mm x 17.5mm), it combines a 160 MHz 32-bit RISC-V single-core processor with flexible connectivity and low power operation. Easy to program via C++, Python, MicroPython or the Arduino IDE, it exposes UART, SPI, I2C and PWM for sensor and actuator interfacing, ideal for battery-powered applications thanks to low power behavior and well suited for wearables, compact sensors and automation projects.

Questions & answers

Frequently asked questions

Yes. It can be programmed in the Arduino IDE using C++ and also supports Python and MicroPython workflows. It is suited for IoT projects that need WiFi, BLE, and a compact ESP32-C3-based development board.
This ShillehTek version comes with headers pre-soldered, so no soldering is needed before basic prototyping. You can plug it into compatible headers, breadboards, or jumper wiring and start connecting peripherals more quickly.
It exposes UART, SPI, I2C, and PWM for connecting sensors, displays, drivers, and other peripherals. The board uses a 160 MHz 32-bit RISC-V single-core ESP32-C3 microcontroller with built-in WiFi and BLE.
Its 20 mm x 17.5 mm size, WiFi, BLE, and low-power behavior make it suitable for wearables, compact sensor nodes, battery-powered IoT devices, and small automation controllers where board space is limited.
The product specifies BLE connectivity, not Bluetooth Classic. If your project depends on Bluetooth Classic profiles or audio-style Bluetooth support, choose a board documented for Classic Bluetooth instead of relying on this BLE-focused module.
