Need to test something minor on your robot but don’t want to commit it to solder? This mini solderless breadboard is perfect! Smaller than a U.S. quarter, this little breadboard will fit just about anywhere. It only weighs 2 grams, too! The board has four rows with four holes each. Four tiny white posts on the bottom (ideal for PCB positioning) can be clipped if necessary.
The Mini Solderless Breadboard can be purchased from Adafruit for just $0.95 per baby board, so stock up!
