Pratham: Breadboardable PIC32 Breakout/Development Board With USB OTG , USB/SDCard/UART Bootloader
Pratham: Breadboardable PIC32 board
doing random projects with Microcontroller i always come into position when i need to have a bit more power and Peripherals then regular 8-bit micro or Arduino has to offer, but most of the powerful micro usually come in non-DIY Friendly SMD package or else they have very less pins like DIP-28.
so what i was need is a fairly small breakout board kind of things which should be easy to handle and should contain few necessary peripherals like bunch of LED ,few switches , USB , EEPROM , VReference for ADC ,Oscillator and Voltage regulators too. and the board also need to be low cost so that i can leave in that in the application as it is. and most important things is the board should be breadboard compatible.
so here is the solution with all of the features i can think off.
