TDK RoboKit 1

Overview

The TDK RoboKit1 is a development board for use primarily with ROS2 and provides a large number of small ground robotics useful sensors including chirp sensors for time of flight (e.g. ultrasonic obstacle detection).

It pairs a 300MHz Cortex-M7 ATSAME70Q21 with an array of TDK sensors and pin headers useful for robotics.

Hardware

• ATSAME70Q21 ARM Cortex-M7 Processor

• 12 MHz crystal oscillator (Pres)

• 32.768 kHz crystal oscillator

• Micro-AB USB device

• Micro-AB USB debug (Microchip EDBG) interface supporting CMSIS-DAP, Virtual COM Port and Data

• JTAG interface connector

• One reset pushbutton

• One red user LED

• TDK ICM 42688-P 6-Axis 32KHz IMU

• TDK ICP-10111 Pressure Sensor

• TDK NTC Thermistor for Temperature

• AKM AK09918C Magnetometer

• 2 TDK HVCi-4223 Cortex-M3 Dedicated Motor Controller

• 3 TDK ICS-43434 Stereo Microphones

• Connector for Industrial Dual IMU (TDK IIM-46230)

• TDK CH101 Ultrasonic Range Sensor Array (9 Connectors, comes with 3)

Connections and IOs

The TDK RoboKit Hardware Guide has detailed information about board connections.

System Clock

The SAM E70 MCU is configured to use the 12 MHz external oscillator on the board with the on-chip PLL to generate a 300 MHz system clock.

Serial Port

The ATSAME70Q21 MCU has five UARTs and three USARTs. One of the UARTs is configured for the console and is available as a Virtual COM Port via the USB2 connector.

Programming and Debugging

Flashing the Zephyr project onto SAM E70 MCU requires the OpenOCD tool. Both west flash and west debug commands should correctly work with both USB0 and USB1 connected and the board powered.

Flashing

1. Run your favorite terminal program to listen for output. Under Linux the terminal should be /dev/ttyACM0. For example:

   $ minicom -D /dev/ttyUSB0 -o
   

   The -o option tells minicom not to send the modem initialization string. Connection should be configured as follows:

   • Speed: 115200

   • Data: 8 bits

   • Parity: None

   • Stop bits: 1

2. Connect the TDK RoboKit1 board to your host computer using the USB debug port (USB1), USB2 for a serial console, and remaining micro USB for power. Then build and flash the Hello World application.

   # From the root of the zephyr repository
   west build -b tdk_robokit1 samples/hello_world
   west flash
   

   You should see “Hello World! arm” in your terminal.

Debugging

You can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b tdk_robokit1 samples/hello_world
west debug
