PIC 8 Pin 20MHz 2K 4A/D - 12F683 Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

2 Soldering

Skill Level: Rookie - The number of pins increases, and you will have to determine polarity of components and some of the components might be a bit trickier or close together. You might need solder wick or flux.

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.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

  • I wish there were more tutorials for these things...

    I'm currently working with Microchip's MPLAB X under OSX with the xc8 compiler. I'm using a PicKit 3 as a programmer. I've made good progress towards getting the software UART implementation working and will write up a tutorial on it once I get it a bit more stable.

    These chips are pretty cool for such a small device! Too bad there isn't an Arduino/Wiring type IDE for them...

  • Hello, how many LED can you connect on each I/O pin ?
    Because in my project I would to connect 7 LED on each I/O pin ... it's to much ?
    PS : sorry for my bad english ... I'm french

    • Use the pin to toggle a FET, that way the FET is sinking/sourcing the current, not the ucontroller

    • 25mA maximum per pin, 90mA total per device.
      A typical LED draws 20mA, so only 1 LED per pin, and only 4 total for the device. You can make the LEDs dimmer by limiting the current, but you'll never get 7 on one pin and be able to see the light. You'll have to use the pin to drive an external transistor.

  • When will you be getting more of these in stock?
