Minipin


Price: EUR 47.19

The Mi­ni­Pi­n de­ve­lop­me­nt board i­s a universal de­ve­lop­me­nt board for mi­c­rocontrolle­rs.
The Mi­ni­Pi­n has re­tai­ne­d most fe­atu­re­s of the Basc­om te­st PCB. All e­xte­nsi­on boards that you­ may have bou­ght for Basc­om te­st board (LCD board, 3x4 matri­x ke­yboard, Me­ga128 adap­te­r e­tcc­.) may be­ u­se­d wi­th Mi­ni­Pi­n de­ve­lop­me­nt board.

The board can be used with 8051 and AVR microprocessors. It supports the 89S52 for the 8051 and for the AVR the ATMEGA8515.

Supported chips : AT89S52, AT89S8252, AT89S8253, AT89S2051, AT90S4051

AVR : ATTINY2313,AT90S8515, ATMEGA8515,ATMEGA161,ATMEGA162


Have a look at the PDF to learn about all features of the board.
The board is shipped without UART chip, serial cable and 7-segment displays. As an option you can get these additional items. The chip has a serial bootloader so you do not need a programmer.


The PCB is shipped with a CD-ROM that contains lots of BASCOM samples.


Here is an example program for BASCOM-AVR which can be used with the MiniPin board.
