BHN-1000 is an experimental equipment to educate Basic Embedded system including C-language Programming and Control, connected with Sensor & Commercial products.


  • BHN-1000 equipment use ATMEGA-128 MPU (low-Power, high-performance). User can study micro-processor Programming, embedded I/O control and RS-485, RS-232C, Ethernet communication programming
  • BHN-1000 designed to help embedded programming study. This equipment have many interesting device to use. (2-line text LCD, LED, Buzzer, Thermometer, EEPROM etc) And this equipmenthave external 32kbytes SRAM, so user doesn't need to worry about large program
  • BHN-1000 support many port, so user can use-type of sensor or actuators. BHN-1000 have analog 4 channel, (8port), digital 16bit output port, digital 8bit input port, high-performance 8 relay ports.
  • User can study specially about the digital communication subject (data encryption / decryption, error-recovery algorithm, communication network methodology.)by connecting the BHN-1000 to BHN-1000 or BHN-1000to other communication equipment
  • LABview Communication & Control Practice


  • Wired communiction with RS-485, Ethernet
  • RS-232C PC monitor functions
  • Remote control function by infrared RX / TX
  • 220V AC, 24V DC ON / OFF conrol by Relay port
  • 1M bits EEPROM support
  • Internal Thermometer
  • 16bit Digital Output, 8bit Digital Input port
  • 4 Channel Analog Input (ADC included)
  • 2 Line Text LED, 8Push Keys, Buzzer, LED User Interface support
