ZL1PIC PCB - PCB of the development kit with PIC16F84 microcontroller

A printed circuit board of the ZL1PIC set.
The ZL1PIC module allows you to conduct experiments with PIC16F8x microcontrollers. The ZL1PIC set consists of two printed boards: base (microcontroller) and LED display. On each board there are mounting areas on which additional peripheral modules can be made and it is easy to test their work. Universal mounting plates can be easily broken off, using appropriate notches to help. The plates are made in two-sided technology with metallization, on both sides are covered with a solder mask, and on the element side there is a print illustrating the arrangement of the elements.
There are several I / O components on the microcontroller board (4 LEDs and 4 micro switches, piezoelectric buzzer) that can be used in any way in your own application. Using the set facilitates the built-in supply voltage stabilizer with the Graetz bridge rectifier on the input, thanks to which it is not possible to damage the set by inverting the supply voltage (8 ... 12 VDC / 60 mA). All port lines: PORTA and RB4..RB7 lines of the PORTB port are connected to the 20-pin IDC connector, which is used to connect external peripheral circuits.
The second PCB can be assembled with a 3-digit multiplexed LED display. The operation of this display is shown in the book "PIC16F8x microcontrollers in practice". All programs presented in the book "PIC16F8x microcontrollers in practice" were tested based on the ZL1PIC set.
