PIC18 development board with ethernet capability

DIY development boards are popular among hobbyists. [magkopian] from Greece has designed a PIC18 development board that features Ethernet connectivity (using ENC28J60) and Full Speed USB 2.0. The development board is based on a PIC18LF4553 microcontroller. The microcontroller features a Full Speed USB 2.0 (12Mbit/s) interface without the need for any external components. Also, it has 32KB of program memory, 2KB of RAM and it supports an external clock up to 48MHz, which is optional because it also has an 8MHz internal clock. The ENC28J60 Ethernet controller is used to provide Ethernet connectivity to the microcontroller thought the SPI interface.

Microchip is launching “Curiosity” development board

Microchip is launching a new development board called Curiosity for 8-bit PIC lovers. It supports 8-, 14-, 20-pin 8-bit PIC® Microcontrollers with low voltage programming capability and has an integrated Programmer/Debugger with USB Interface that is fully compatible with Microchip’s MPLAB X development environment. Your next embedded design idea has a new home. Curiosity is a cost-effective, fully integrated 8-bit development platform targeted at first-time users, Makers, and those seeking a feature-rich rapid prototyping board. Designed from the ground-up to take full advantage of Microchip’s MPLAB X development environment, Curiosity includes an integrated programmer/debugger, and requires no additional hardware to get started.

PIC24 Development Board

Brian Dorey shares the schematics and design files for his PIC24 Development board that works with the PIC24FJ128GC006 as well as DSPIC33EP256MU806 dsPIC series microcontrollers. The prototyping board was designed with removable daughter boards for the microcontroller.  This means that we can use several different microcontrollers on the same board and if we accidently do something that damages a part of the microcontroller it is easy to replace it without having to unsolder the chip. The PIC24FJ128GC006 includes a USB port so we added one onto the board, this will come in handy if we want to design any devices that
