8051/PIC/AVR/Arm/FPGA/Development Board
We offer Development Boards, which are very effective and useful to the embedded enthusiast/engineers. As most of the basic & intermediate ICs are on board. The developer will have to connect the required IC or interfacing devices by using the hook up wires/cables thus, the hard ware building time is reduced. The embedded engineer can focus on developing & testing his own routines. The data sheet for each board along with the sample programs will be provided for the convenience of the embedded engineer. These Development Boards are designed and developed under the supervision of highly qualified and experienced professionals who have expertise in this field. We also offer servicing and organize and systematic training of Development Boards by meeting international quality standards.

Encoder Board

Decoder Board

• To interface without distortion RF Tx Rx to microcontroller use encoder and decoder boards. In the same frequency 433 MHZ, you can transmit four different data in D1 D2 D3 D4. It is very easy to use just insert the RF Tx RX into burg female connecter as shown in the PCB.


• Without microcontroller in RF transmission you can switch on 4 relays using this board, if you connect 1 to D1 in Tx input, output of Rx will be 1 in D1.

L298 is a Monolithic Bridge High Current Driver
L298 Board can be used to drive two phase bipolar and four phase uni-polar step motors in microcontroller controlled applications. Another application is DC MOTOR, we can drive 2 Dc Motor in forward and reverse through microcontrollers, inputs and outputs are shown.
