Expansion Modules


Pascalite Add-ons

These are a number of add-ons for the Pascalite boards available now:

  • LCD-module
  • realtime clock module
  • I/O-expansion module
  • LED-module
  • temperature sensor
  • iButton readers
  • almost all I2C-devices

LCD-Module
(for Piccolo, Plus and Pro)
This module consists of a lcd-display (16×4 or 20×4 characters) and a special driver to connect it to an I2C-bus of Pascalite microcontrollers.The driver contains a microprocessor that converts incoming I2C-data and displays it.LCD LCD16x4
Real-time Clock
(for Piccolo, Plus and Pro)
Easy to use clock-module, connects to an I2C-bus.
Resolution: 0.01 sec.This module is integrated on the Pascalite Pro Board.
Clock
I/O-Expansion Module
(for Piccolo, Plus and Pro)
This board expands a Pascalite system with 8 digital I/O-lines, which can be accessed by a single byte (both reading and writing). The board contains a PCF8574 or PCF8574A chip.Up to 16 I/O-expansion boards can be attached to an I2C-bus, expanding the system with up to 128 I/O-lines.
I/O
LED-board
(only for Plus)
Boards with LED’s (5mm) on the 8 I/O-lines
and two small prototype areas.
LED
Temperature sensor
(for Piccolo, Plus and Pro)
A 10-bit temperature sensor which can be connected to the I2C-bus of Pascalite Microcontrollers.
Temperature
iButton Probe Starter Kit
(for Piccolo, Plus and Pro)
This starter kit contains an iButton-reader, 3 iButtons and 3 key rings.The reader can be attached to the I/O-connector of the Pascalite Boards.
iButton Probe
iButton Board Starter Kit
(only for Plus)
This starter kit consists of a small board containing an iButton-reader, a few LED’s and two prototype areas, and comes with 3 iButtons and 3 key rings. The board can be attached to the I/O-connector of the Pascalite Plus Board.
