The all New AT89S52 Development Board-Mini can be used to evaluate and demonstrate the capabilities of Atmel89S52 microcontrollers. Since all I/O pins are broken out on Male and female Berg strips, it is very easy to use for development purpose as well. The board is designed for general purpose applications and it includes a variety of hardware to exercise microcontroller peripherals. Onboard Mini Bread board is provided to ease the use,Ideally suitable for training and development purposes. Apart from this there is an onboard 2MM pitch Female sockets on both bottom and top side to insert Xbee module as per convenience. Since there are different modules ( GPSBee, Bluebee, RFBee Etc) are available in the XBEE form factor, it will be easy to interface and experiment all of them .Onboard 5v to 3v3 MOSFET based level converter and 3V3 Voltage regulator provide safe interface to XBEE and other low voltage devices .The onboard 5V regulator is having current rating of 1A and  3V3 voltage regulator is having 500mA capacity to easily power almost all onboard devices as well as external devices. All I/O pins and Power pins (5V & 3V3) are made available at Female header pins around the Breadboard to ease the wiring. Apart from this the All I/O pins are ready at male berg strips in two rows under the LCD. The UART pins are available at separate RMC Connector with power (VCC & GND). A 3v3UART is provided with the help of onboard MOSFET voltage level converter.
  The onboard mini-B type USB connector can be used to power the board as well as to communicates with PC. A jumper is provided to select the PC interfacing method (USB or RS232). The development board can be programed by internal bootloader(philips 89V51RD2) or ISP Programmer.A separate 2x5 pin shrouded male connector  has been provided to connect  philips and atmel ISP Programmer/Debugger. Apart from USB the board has two more powering options like DC Adapter jack and 2Pin RMC connector with Reverse polarity protection. Available onboard peripheral interfaces are 3nos Pull-up switches, 3nos LEDs,buzzer,16X2 LCD,RS232,USB,Voltage Level Converter and connectors for xbee, sockets for RFID Module (EM18 or uRFID) ,SERVO Motor, UART, Isp programmer/Debugger etc.

  All these peripheral interfaces can be disconnected by removing onboard PCB jumpers to free up the I/O PINS for other purposes.

Note: Separate programmer required for programming this device, we recommend buying
