The SAMD21G Mangler is a unique programming board that allows you to install bootloaders and code onto loose SAMD21G 48TQFP ICs without having the chip soldered to the board.

Perfect for pre-programming SAMD21G chips for use in kits or for use on PCB's that don't have an IDC header or pins broken out for bootloader installation!

The entire Mangler is just a PCB with a 3D printed board holder and Chip placement/holder.

Check out the product showcase video below!

Sure, you can buy more expensive adapters that you can put your SAMD21G into, but then you also need to build the electronics that go around it to make it work and then add adapters for both the IDC ICE header and a USB header in case you also want to pre-load Arduino code onto the chip.

With the SAMD21G Manger, all of this is done for you. Just attach the ICE cable and a USB (Micro-B) cable, place your chip on the pad, place the Chip holder on the top and gently wiggle it to alight it.

Then program away!

Why the SAMD21G?

Why do I focus on the SAMD21G specifically? Well it's an awesome micro-controller used by many manufacturers for both production hardware as well and high profile development boards like the Adafruit Feather m0 and SparkFun SAMD21 Mini Breakout.

This Mangler board is for the 48TQFP package, that has the 48 pins sticking out, as it's the package I prefer to use in my projects and products.

The SAMD21G Mangler is compact and very easy to use, in-fact I use it for production work to pre-program SAMD21G IC's for my other products and projects. Talk about eating your own dog food!

Each order includes

• an assembled and tested SAMD21G Mangler PCB, with holder attached
• 2x IC holders. Always handy to have a spare!

Why is it called a Mangler?

Ha, glad you asked! Well, originally I was unsure if the concept was going to work and my expectations (like with many of the ideas I come up with) was that I was more likely to mangle my SAMD21G chips than I was to have a working proto-type... and well, the concept worked first time, but the name kinda stuck ;)

Open Source

This project is also open source, so the PCB design files, gerbers and STL files for the 3D printed parts are all available below in my Unexpected Maker Github. If you'd like to get your own PCB's printed and 3D print your own holders, that's ok with me!

VIVA LA OPEN SOURCE HARDWARE!
