“Powerful 32-bit ARM Cortex-M4 microprocessor with integer divide and floating point. Features an inertial measurement unit (IMU) connected to the internal I2C bus (Wire1) and Adafruit breakout boards can easily be connected to external I2C. Note: 5V power supply is not available until solder bridge is made on reverse side of board.
Bought together with an MCP9808 temperature sensor to do as a My First Arduino Project. After soldering the header, connecting up and running a test program was a doddle.
Believe it can only be programmed via USB although Bluetooth serial monitor is an option. Superb value if you want to dive straight into making with little or no fuss.”
