VM142
Features
9 free programmable I/O’s (4 in-, 5 outputs)
PIC16F630 Microcontroller from Microchip®
onboard
LED indication for power supply and relay
output
1 free programmable LED indication.
Onboard mini buzzer for audible signals.
Onboard ICSP™ connector for
programming.
PIC™ programmer support PIC16F630
* software development tools like assembler or C are not
included.
This application module seems small but is big in performance,
all depends on your programming skills.
Now you can create your own custom application without the
hassle of making the hardware.
All the buffered inputs and outputs are ready made for you, the
module features on-board LED, a relay output and a buzzer.
Make your own automation,
controller, car applica-
tion…
All you need is one of our
programmers like VM134
or K8076.
In-Circuit
Programming is also possi-
ble, making development
even easier.
