8051 Single Board Computer

New Microprocessor learning board demonstrates exemplary design of 8-bit single board computer. More peripheral and easy to adapt to be a dedicated controller.

8051 Microcontroller Kit

8051 kit using 7-segment display and hex key monitor. The design is simple, small number of components and cheap. The size is compact, 5.3x5.7 inches. The keypad is ergo design for young students. The kit is 8051 based microcontroller. So many chip makers produce the 8051 core microcontroller. The kit is available for both preassembled and kit form.

 8051 Microcontroller Kit

8051 Single Board Computer

The new 8051SBC features;
  • CPU: Any 8051 compatible with 40-pin DIP package @11.0592MHz
  • MEMORY: 27C256, 32kB EPROM for monitor program
  • 62256, 32KB SRAM for both code and data space
  • I/O: direct cpu bus interface 2x16 line LCD
  • MEMORY and I/O Decoder: GAL16V8D
  • EEPROM: 24LC256, 32KB serial eeprom
  • RTC: Real-time clock, DS1307 with +3V Lithium backup
  • ADC: LTC1298, SPI interface 2-channel 12-bit Analog-to-Digital Converter
  • I/O pins: P1,P3 of 8051 cpu, 16-bit I/O port
  • Keypad and DIPSW: 4-bit keypad and 4-bit DIP switch
  • RS232 Level Converter: MAX232
  • RS485: 75176 differential transceiver
  • Serial Interface: 9600 8n1
  • Monitor Program: Modified PAULMON2 including new commands
delabs Notes -
 
This is an Educational Masterpiece, with more Relevance to Asian Students. I took my first steps with 8085, Z80 and later 8749. Then the 80C51. If you start writing code for 8080, you will want features which will come in 8749 and when you study 8749 and think of enhancements 80C51 will pop out as if they read your mind.

Once you work with these, then you can use all the new uC and uP easily. It is better you write code with as less EPROM or Flash as possible. This will help you make quality code. The smaller the code the more real time your firmware and lesser bugs.

USB Serial Interface for Android

There are many Serial Data Devices that means those that use the RS232 (old mouse port). USB is now the standard interface in most computers and embedded devices. Many mini embedded sensors and devices come with High Speed Serial Interfaces.

USB Serial Interface for Android

This page lists solutions and methods to get These Devices talking with your computer. The focus will be HandHeld Computers made of the Android OS. This way you can get your hand on the Real World thru USB and Serial. USB to parallel also helps when you want to control a Relay or Solenoid Array. Wireless Interfaces also are a good Solution with Networking.
