Through-hole development board for 18-pin PIC microcontrollers

in project logs by DP | 4 comments

Raj made an all through-hole development board for 8bit PIC microcontrollers. Feature list is quite impressive:

  • An ICSP header to connect PIC16F1847 to PICkit3
  • On-board voltage regulator (+5 V)
  • A HD44780 based character LCD display
  • 8 LEDs to read the status of output pins
  • 6 Tact switches for providing inputs
  • A potentiometer for providing analog input
  • TTL to RS232 voltage level translation and vice-versa for serial interface
  • An external serial EEPROM (24LC512)
  • A GPIO expander (MCP23008)
  • Quad OpAmp IC (MCP602) for signal conditioning
  • Digital potentiometers (DS1868)
  • Programmable gain amplifiers (MCP6S92)
  • A temperature sensor (TC74A0)
  • A mini breadboard

The PIC, as well as all the peripherals, are broken out to female headers. You simply use wire jumpers to make connections.

    Great setup!

    Glad to see someone likes doing stuff with PICs too

    Wow that’s very tidy!

    Nice work. Kind of reminds me of the X-in-one Electronics Kits with the coiled spring contacts I used to have many years ago.

    If you ever need more power then upgrade to the new DIP PIC32s! :D
