is an open source electronic board developed around a powerful 8-bit microcontroller. It is useful to learning how to use microcontrollers and for rapid development of prototypes. It is equipped with an USB connector for communicating with a PC, a connector for a (not indispensable) in-circuit programmer and debugger. It provides two in-line connectors to be plugged into a breadboard or an external circuit. It may therefore work as a pre-assembled module integrated in a very complex system.
can work as a stand-alone module, or can be connected to sensors, buttons, LED or LCD displays. It can be used to switch on and off lights, electric motors. It can communicate with other modules and all kind of peripherals. Even if you are an absolute beginner, if you want to learn how to use microcontrollers, if you need a way to fabricate cost-effective prototypes easily or if you are a student, Pierin PIC18 is the platform for you.

The circuit

The circuit is quite simple and allows to begin practical applications and experiments in a very short time. In fact, having a working board straight from the beginning allows to begin immediately tests and programming. You will not need to assemble any circuit, and you will not need any external power supply. In fact, the board is able to be powered by the USB connection (but not only). Here is a list of characteristics:
  • Built-in 3.3V voltage regulator, to power the Pierin PIC18, as well as external circuits up to 250mA.
  • Possible operation as a stand-alone module.
  • Pre-loaded Microchip bootloader. You will not need any external hardware programmer or debugger to start your experiments.
  • Compatible with the (optional) PicKit3.
  • Power supply from USB, or from an external circuit.
  • Microcontroller I/O pins available in a connector with a standard pitch, compatible with a solderless breadboard.
  • Two MOSFET-buffered LEDs which do not load the micro's pins.
  • Two buttons connected to the microcontroller with pull-up resistors.
  • A reset button.
