Description
Built on the basis of STM32 F103RET6, 72 kHz, 64 KB SRAM and 512 KB Flash memory. It can be programmed viathe Arduino IDEusing the available libraries. In addition to the traditional characteristics of the boards, Arduino hasa BLE CC2540system, which enables communication via Bluetooth 4.0, twoHR8833 dual-channel motor driver with the performance of 1.5 A and automatic detection of power source.
The board contains the STM32 F103RET6microcontroller, equipped with 10 digital inputs/outputs and 5 as analog inputs. The module also has: a microUSB connector, screw power connector, RESET button and BOOT, and leads to connect the motors and sensors from theGravity series.
The module operates with a voltage of 3.3 V. To connect with 5 V chips, signals should be connected via voltage converter. The device has many additional features that do not exist in traditional Arduino boards:
- BLE CC2540 moduleby Texas Instruments- a system that allows for communication and programming via Bluetooth in a range of 50 m, in open space
- LEDs -the device informing about the status of voltage, communication and wireless connection
- 2 xdual-channel HR8833 driver of engines - it works a little differently than universal L298, the details are inthe driver's documentation.
DFRobot company introduced colored connectors that facilitate the identification of the leads:
- red- power pins
- blue -analog pins
- green- digital pins
- black- ground
To start the module, you must connect the system to computer usingmicroUSB cableand act in accordance withthe user manual. |
Power
The module can be powered via the USB cable and the external device, for example, the AC adapter. Switching the power sources is automatic. The power supply is connected to the pin connectors. You can also power the module via the microUSB connector.
