28 Pin PIC Development Board Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

1 Electrical Prototyping

Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

    does it work well with the 18F* series controller?

    • MikeGrusin / about 10 years ago / 1

      Yes, double-check the pinout against the schematic, but it should.

    Instructions on wiring up the serial port are wrong.
    Correct instructions are:
    Solder 2 wires:
    1/ ( PIC Pin 17 ) RC6 / TX1 to PCB label RX ( MAX232 Pin 10 )
    2/ ( PIC Pin 18 ) RC7 / RX1 to PCB label TX ( MAX232 Pin 12 )

  • Hiii!!hello! simply a question, any idea when the 28 pin development systems are going to be out of stock?
    Thanks a lot!!

    Check your PIC before ordering, there is no way this board will work with all of them.
    The PIC24HJ, for instance, has power (and ICSP, and everything else) on different pins.

    Even better than I expected. The only thing that held me up for a little bit was that you have to manually hook up the UART to the RS232 IC. Works perfectly with the PIC-PG1 Serial Port Programmer.
