In the middle of the page is a MCP1525 voltage reference chip and the Target programming header. Above that is a MCP601 op-amp and voltage boosting circuitry. At the bottom is a LTC4411, a MAX893L, and associated circuitry that among a couple other things, controls the power to the programming target, if it is not self-powered, and this device is supplying power to it. Directly below the MCU is the MCP1727 voltage regulator. In addition to these components, the USB connector is shown, as well as the status LEDs and OTG Button connections. There are the requisite capacitors and 12MHz crystal attached, as well as a programming header to load its firmware. First – in the upper left corner is the pic24 processor that controls this device. I’ll briefly talk about the different sections that I have labeled above. This schematic is very similar to the one Hendrik used, with a couple component changes and a fix for a PNP transistor that was shown backwards on his schematic. It is pictured below, and here is a link to the full-sized PDF: My Schematic After looking at the one from Hendrik’s blog post above, and also studying the actual Microchip pickit 3 schematics that are publicly available in the documents released by Microchip, I came up with the following schematic. With that in mind, I set out to create my schematic.

I decided that I would design my project to use surface mount components and a purpose designed PCB. As impressive as that is, I was looking for something a bit sleeker – especially since I was looking at some point to modularize it and use it on other designs. The version that was built on the blog linked above, was done so on a protoboard using a variety of components, and was completely hand-wired. I was excited to see some real information about the process, and set about determining how I would do the same, now that I knew someone else had verified that it would work. This Individual had created his own version of the Pickit 3 and had posted his method for doing so. After a while I came across a post – From this blog
#PICKIT 3 CLONE VS ORIGINAL 32 BIT#
Initially, I found lots of posts regarding the 2nd version of the Pickit – the Pickit 2, but not as much regarding the latest version – the Pickit 3 – which is what I need to program the 32 bit pic processors that I am using. As I became more interested in that idea, I began to search the web to see if anyone else had already done something similar. After using the Microchip tools to program and debug the projects I work on, I wondered about creating my own programming/debugging module that I could put on my own boards – just like Microchip does with their starter kits and such.
