• control of 4 DC motors of various types from 6 to 1 2 V. The set includes 3 elements:
1 . Controller "Trackduino PRO" (Controller can be purchased separately).
2 . USB cable.
3 . Case for 9 B batteries.
Technical characteristics of the Trackduino PRO controller:
1 . Computer connection - USB or Bluetooth.
2 . Built-in Bluetooth, allows sending-receiving data, flashing the microcontroller.
3 . 5 programmable buttons, each of which connects to its own I / O port. This, together with the RGB LED, will allow for a minimal human-machine interface without connecting any external devices.
4 . Slot for microSD memory cards for realizing the possibility of expanding the permanent memory.
5 . Power supply from 7 V to 1 2 V, 2 power connectors - a jack for accumulator blocks and a bolt terminal block for connecting any other power sources from 6 to 1 8 V.
6 . Brought out for convenient connection 8 input ports with supplied power (GND-Vin-S), all with digital-to-analog converter, 1 - 4 with interrupts, selectable supply voltage: 5 V / 3 V.
7 . Output ports for convenient connection 8 output ports with supplied power, 1 - 5 with hardware PWM (pulse width modulation) signal for controlling third-party devices chips, selectable supply voltage: 5 V / 3 V.
8 . Output 4 ports for connecting DC motors on 2 x L 2 9 3 drivers with overcurrent protection. Each of the channels is controlled via 2 output ports for selecting the direction of rotation and braking, as well as through an additional port with a PWM signal for controlling the rotation speed.
9 . Standard interface Arduino UNO R 3, independent of other I / O ports, allows you to connect any shields and libraries for Arduino. Additionally increases the space for connecting external devices by 2 4 I / O ports.
1 0 . Three-color LED that can be programmed to light up with any of ~ 1 6 million shades. It will allow realizing a visual indication of any events or parameters.
1 1 . 2 outputted USART ports with power (RX, TX, 5 V, GND).
1 2 . 2 outputted I 2 C ports with power (SCL, SDA, 5 V, GND).
1 3 . Switching between BOOT modes: RUN and DFU.
1 4 . Central processor: STM 3 2 F 4 0 7 (1 MB flash memory).
