Summary of Self-made development board for the 32-bit PIC32MX220F032B Microcontroller
The article describes a self-made development board for the PIC32MX220F032B microcontroller, featuring USB or external power, two push buttons, two LEDs, and connectors for breadboard integration. It highlights the use of a one-sided PCB with minimal bottom-side traces for easy fabrication.
Parts used in the PIC32MX220F032B Development Board:
- PIC32MX220F032B MCU
- USB connector
- External power source input
- 2 Push buttons (Reset and user-defined)
- 2 LEDs (Power and user-defined)
- 6 pin wide ICSP connector
- 28 pin wide DIL connector
- One-sided PCB
Few months ago Microchip introduced smallest, lowest-cost PIC32 microcontrollers – new PIC32”MX1” and PIC32”MX2” families. PIC32 MX1 and MX2 MCUs include up to 32 KB of Flash and 8 KB of SRAM, two I2S interfaces for audio processing, 10-bit 1 Msps ADC, an 8-bit Parallel Master Port and serial-communications peripherals. MX2 MCUs also have USB 2.0-compliant full-speed module.
For the prototyping purposes I made small development board with PIC32MX220F032B MCU. This board includes all of the external circuitry needed to get the PIC32 up and running. Power can be provided over USB or from an external source. It has 2 push buttons (Reset and 1 user-defined button) and 2 LEDs (Power and 1 user defined LED).
Board has 6 pin wide ICSP connector and 28 pin wide DIL connector on the bottom that allows to plug this boards directly into a bread boards.
This board is easy to self-made. You can use one-sided PCB – most of traces are on the board‘s component side; only 5 of them are on the bottom side.
