CHRP4 USB robotics development board

CHRP4 (Common Hardware Robotics Project - version 4) is designed to help beginning computer technology learners quickly develop programming and interfacing skills while building simple line following, obstacle sensing, and Sumo robots. CHRP4 is a robotics-focused derivative of UBMP4 (https://hackaday.io/project/184126-ubmp4-usb-picmicro-development-board) – the reference to ‘Common Hardware’ in its name. CHRP4 features built-in pushbuttons, LEDs, a piezo speaker, and a motor driver IC so learners can start developing programs without wiring up or breadboarding any external circuits first. CHRP4 is programmed in C using Microchip's MPLAB X desktop IDE or the MPLAB Xpress cloud-based IDE. The on-board PIC16F1459 microcontroller can be pre-programmed with the USB µC bootloader (https://hackaday.io/project/63204-usb-c-usb-pic-bootloader) making programming as easy as dragging and dropping a compiled .hex file onto it!
