Its Bitsy M4 and breadboards

by mwhuffnagle on Sun Dec 02, 2018 9:26 am

I bought an Itsy Bitsy M4 and it really is a cool little micro controller.

I have two questions about it and breadboards:

1) How do you use the pins on the end of the board like GPIO 3 & 4 on a breadboard because if you solder headers on them, they connect to each other as well as the Rx pin when the MCU is mounted in the breadboard? So, they would short each other out.
2) When headers are soldered in for the end pins from GPIO 2 to the Rx pin, that's 7 pins wide and all of the breadboards that I've seen or bought from AdaFruit have a 5xx5 configuration with two solid spaces between the two sets of 5 holes on each side of the middle blank area. Besides the common/shorting issue for those pins, as described in question 1, how are you supposed to use the headers on those pins in a breadboard?

Thanks,

Mike

The itsy-bitsy is designed for minimum size. It is not optimized for breadboard use

If you want to use the pins on the end of the board in a breadboard, you can install the header pins from the top and use female jumpers. https://www.adafruit.com/product/794

Or you can use test points and clip-leads: https://www.adafruit.com/product/3823
