A general purpose 40 pin 8051 evaluation board with just the bare essentials required for using a 8051 microcontroller - port extentions, crystal circuit, reset switch, power status and a general purpose LED. This board is perfect for building rapid prototypes and projects. The board provides port extensions for all ports and also provides an empty hole for each IO, where wires and connectors can be soldered directly for further expansion.
The board features a DC Jack for power input and can be directly powered from our 5V SMPS Power Supply.
The board is built on a high quality FR-4(1.6 mm) board with a green solder mask and a clear and legible white legend. All I/O pins are labelled with their names along with any dual feature they support. This greatly simplifies prototyping
Input Voltage: 2.7 – 5.5V (depending on the microcontroller used)
Power Status LED(Green) along with a general purpose LED connected to P1.0
If you plan to use this board, we recommend buying the following products too -
AT89S52 - a 40 pin 8051 microcontroller. Can be used with this board. Requires external hardware programmer to upload codes to it. Or,
P89V51RD2 - a 40 pin 8051 microcontroller. Can be used with this board. The P89V51RD2 is recommended over the AT89S52 because programs can be directly uploaded through a serial connection to a computer. All codes written for the AT89S52 are compatible with the P89V51RD2
5V Voltage Regulator Board - a regulator board to power the board from 7 - 20 V AC or DC supply voltage. You may use a transformer to step down an AC voltage, apply it to the regulator board and power this board
5V LDO Regulator Board - a low drop regulator board which takes 6.2 - 15V DC to regulate it to 5V. Great for powering the board from batteries and solar panels.
USB to Serial TTL Converter - use this converter to directly upload codes to an onboard P89V51RD2 through USB. You can also use this to do serial communication between the microcontroller and the computer through USB
Jumper Wires - for connecting the board to our sensors, motor drivers, breadboards, etc
