ATtiny2313 Robot development board with twin L293D chips and MAX485 RS485 Port

ATtiny RS485 Quad Motor Control board is a AVR development board with 20 pin ATtiny2313 microcontroller along with Motor control and RS485 communication Ports. The motor control section contains two L293D chips and the RS485 communication section is build around the popular MAX485 chip from Maxim.

The Board is designed for controlling upto 4 DC brushed motors bidirectionally(Clockwise,Anticlockwise) or 8 motors unidirectionally through a serial interface like UART or RS485 port. You can use the board as a slave unit for controlling the motors of your robot through a serial interface which will save the pins of your host microcontroller.Ideal for your next robotic Project.

The user can also select the voltage levels (5V and 12V) at which the motors are driven using a jumper. This provides a flexible way for connecting a variety of motors to your board. 

The 12 LED's present on the board shows the Logic Levels of the 2 L293D chips on the board. 

Screw terminals on the board provide an easy way to connect your motors to the board. Extra 12V ,5V and Ground Pins are available.

The Board can be easily programmed using any commonly available AVR programmers like USBtinyISP.

thanks,gr8 board for building robots

Purchased this board few days back. Its working fine. The build quality is good.One thing i like is that the main chip and the motor driver chips of the board are removable,you can reuse them if u want:-)

Working fine, checked it using 2 motors

thanks rxed the brd
