Freedom
Freedom is an embedded system mounting 40-pins PIC microcontrollers, developed to suit a wide range of applications, without additional external hardware. Nevertheless, Freedom is a very small system. In 8.3cm x 10.7cm host a 40-pins PIC microcontroller with the possibility to use the following hardware:
I2C EEPROM memory.
Real Time Clock/Calendar.
RS232 Interface.
RS485 Interface.
Alphanumeric LCD with contrast trimming.
Voltage regulator for servo motors.
Photocell to detect the light intensity.
Temperature sensor.
Connector compatible with ultrasonic sensors
Reset switch.
On board 5V power supply with Led indicator.
On board programming connector.
Each Port is connected to an ICD socket.
