Feature
- The First STM32-Powered XIAO: Built with the STM32C5A3CG, featuring a 144MHz Arm Cortex-M33 processor, floating-point support, and DSP instructions for embedded control and sensor processing.
- CAN FD Connectivity Built-In: Two native CAN FD interfaces, with one channel connected to an onboard TCAN3403-Q1 transceiver and accessible CANH/CANL pads. Add an external transceiver to use the second channel.
- 6-Axis IMU with Programmable Heating: The onboard LSM6DS3TR-C accelerometer and gyroscope are paired with dedicated heating resistors around the sensor. GPIO-controlled heating enables programmable warm-up and, with temperature-feedback firmware, closed-loop temperature regulation to help reduce temperature-related drift in robotics and motion-sensing applications.
- 16MB External Flash: Store application data, sensor logs, configuration files, and CAN message records using application firmware.
- External Crystal for Communication Timing: An onboard high-speed external crystal provides a clock reference for CAN FD and other timing-sensitive applications.
- USB-C and Battery Charging: Develop over USB-C or build battery-powered devices using the onboard lithium-battery charging circuit and battery connection pads.
- Compact, Integration-Friendly Design: The XIAO form factor and castellated edge pads support breadboard prototyping with headers and integration into custom carrier boards.
