A very tiny motor driver board with two laser-driven Time-of-Flight distance sensors. The motor driver is TI DRV8830, which enables motor speed and direction control. ToF sensors are STMicro's VL53L0CX, which measures high precision distance by Infra-Red planar laser through ToF from sensor to object. DRV8830 and VL52L0CX are connected through I2C bus to MCU ATmega328P-MMH. MCU is already Arduino bootloader written so motor driver and ToF sensors are programmable through Arduino IDE via on-board USB-serial interface (CP2102).
I always love to make something by an exotic sensor. This time I found the Time-of-Flight distance sensor, whose size is much much smaller than a conventional supersonic distance sensor, it is small enough to fit inside a tiny 9-mm gauge train. I've got some experience to make tiny Arduino by, for example, SDuino and this time I make everything fit on a tiny board. Just an MCU and distance sensor is not so interesting, soI also put I2C motor driver (DRV8830). In addition, USB-serial interface is implemented by CP2102.
All in one. This tiny board is already Arduino and we can program by just connecting USB cable. (No need for any additional interface. )
Tiny but has two distance sensors and one DC motor controller on-board!
ToF sensors are incredibly tiny but give us high precision distance measurement.
DC motor driver (DRV8830) enables motor-speed control by variable voltage and rotation direction.
The following movie is an example to put on N-gauge motor-car. This example implemented by constant speed but more intelligent speed control will be possible. This sample code is available at github

From childhood, I've loved making electrical things by soldering for some amateur radio related thing.
After graduated certain university and taking Ph. D, I did have a GaAs MMIC design working for 60 GHz system
but it's a bit long time ago.
I always love making something and would like to share my joy. Please enjoy my store!
