Specifications & features
SPECIFICATIONS & FEATURES
The VM142 is equipped with a popular 8-bit Microchip
®
microcontroller. The
PCB layout is designed in such way to include 4 buffered inputs and outputs, a
potential-free relay output and an onboard buzzer. The PIC™ microcontroller is
freely programmable and the software can be developed in Assembler,C or
even special versions of Basic,Pascal,...
Note that a certain level of experi-
ence in PIC™ microcontrollers and their programming is required.
