How to use TQFP 48 breakout boards?

[cvriv]

I bought some new TQFP 48 MCUs and I noticed that the breakout boards for this package wont fit directly to a protoboard for prototyping. Anyone use these and how do you prototype with them other than connecting a whole bunch of jumper wires? I did find some breakout boards that will fit on a protoboard but they wont arrive till maybe mid August and they're kind of expensive, more expensive then the MCUs. LOL.

I have a couple of 240×320 IPS display modules with a 50-pin 0.5mm pitch flat flex cable.  I did happen to find some DIP adapters with a FFC connector on them, but if I hadn't, I'd designed my own in EasyEDA and get a set of five made by JLCPCB for USD $2 + shipping.

I myself am just a hobbyist, but I've made some boards this way, and it's worked for me.

I did design a TQFP44 with 0.8mm pitch to DIP adapter for someone else at this forum, for straddling the middle gap in a protoboard setup, but I never had the boards manufactured as I don't have any chips to try it with.  I think it would be better with 20mil traces (0.5mm), moving the four squiggly traces just a tiny bit.  As this adapter is single-sided, it might make sense to put the bypass caps and maybe even the resonator on the underside – there is plenty of room to route them through vias to the underside on a two-sided board; this one is completely single-sided –, if their height is less than the height of the DIP pins you use.  (There are ones with tall plastic part, though.)

What I'm saying is that making your own is not hard, and is definitely not expensive, and does not require you to install any software on your computer either.  If I can do it, so can you   Worth considering, at least, methinks.

Sorry for the late reply and thanks for replying! So I spoke to a buddy of mine that works at the college I attend and he said that if I wanted to design my own boards I could use the colleges ability to make boards. They have the whole UV light etching setup going on there. The college owes me sometime in there anyways because I didn't get to explore that whole process very well during my senior project class because of the whole virus thing.

Thanks!

I got one of these off Amazon for a QFP-64.  They have 48s as well.  Unfortunately, they are a bit spendy. [ Specified attachment is not available ]

this one is cheap

Very expensive. There's no way im going to pay that much for those boards. I'm going to wait to design and make my own.

Yea I bought several of these. If I start working with these MCU's before I can make my own boards, I'll figure out a quick way to get these boards to connect to the protoboard.

[kripton2035]

also something like this one

is more expensive, but will be easier to place on a breadboard.

you can also make your own board as stated earlier in this thread. if you need more than one this is the cheapest option.

and finally the one I was searching for at first : https://www.adafruit.com/product/1377
$6 for 3 items.

To avoid the 'whole bunch of wires' situation, I created this board that includes a prototype area for housekeeping and application.
It was featured on the mailbag

Been there couple of times...
Alas SMD stuff requires a full box of these boards so you can  live with smd...

BE WARNED THAT UNLIKE DIP QFP AND QFN HAVE DIFFERENT PINOUTS!!!

So even using the breakouts for qfp or qfn you CAN NOT directly plug as DIP..
