20 Pin MCS-51 evaluation board with AT89S2051

20 Pin MCS-51 is a proto AT89S2051 microcontroller-based board that has a UART RS232 communication port and supports In-System Programming for microcontrollers featured ISP. The module is equipped with a pad array for additional circuits, so the module is very suitable to experiment, create a simple application, or create a prototype. For example: LED display controller, motor driver controllers, robot motion control, data exchange with a computer, a digital sensor reader.

  • AT89S2051 based microcontroller with 2K bytes Flash PEROM and 128 bytes of RAM.
  • MCS-51 variant supports 20 other pins, among others: AT89Sx051, AT89LPx051, AT89Cx051.
  • 15 channels input / output.
  • Provided the path that connects to RST pin, X1, and X2 microcontroller.
  • Input power 9-12 VDC, +5 VDC output voltage available for the application circuit.
  • 5x2 headers available for programming using the device in-system programmer Atmel standard.
  • 1 piece of serial communication line RS-232 UART with RJ11 connectors.
  • 11.0592 MHz crystal frequency.
  • External reset circuit with brown-out detector and manual reset button.
  • Prototype area consists of 787 through-hole pad suitable for DIP components (pitch = 0.1 ").
  • There are three lines of pads that are connected in a row and can be used for power supply lines (VIN, GND, +5 V) or other pathways.
  • Equipped with a testing program to test port 1 & 3 and the serial communication port RS232 UART.
  • Dimensions: 10.1 cm (W) x 9cm (L) x 2.2 cm (H)
