Microcomputer Modules

UCB/PIC-B (Universal Control Board based on PIC CPU) has been produced since 1994. Even though it is a very very old design, it is still being used for its brilliantly simple use. Especially thanks to the built-in programming language interpreter (PBASIC), which allows you to create a control program on any PC and load it on “click” into a microcomputer module. Each of the eight pins of microcomputer can be configured as a logical input / output port, serial asynchronous input / output line, synchronous input / output line, PWM, can generate frequency, measure pulse length etc. More about programming in manual.




  • clock frequency 4 MHz
  • 256 B EEPROM Memory
  • 8 input / output lines that are fully controlled by program commands
  • integrated interpreter of the PBASIC language
  • execution speed: about 2000 commands / sec
  • serial TTL communication speed, 300-2400 baud
    (I / O pins)
  • temperature range 0 ° C to 60 ° C


The interface adapter enables the UCB/PIC-B microcomputer module to be connected to the PC via a serial line, the correct orientation is indicated >> on both PCBs, the connector is DB9F.

If there is no serial port on your PC, it is usually created as a virtual port on the USB port using an adapter. This is either a standalone or built-in USB cable. You need to be sure that the software driver will be supported by the operating system, we recommend hardware based on the FTDI chip.

Variant 1

Variant 2


The adapter (FTDI) creates a virtual serial port, ending with the DB9M. Use USB cable USB A – mini USB B.


The virtual port adapter is built-in directly into the USB cable ending with the DB9M connector. An alternative is the compact USB-DB9M adapter.
