Crocodile Clip with Wire Leads (10pcs)
This is the crocodile or alligator clip cable. Connect to your component lead or pads (for example micro:bit) without soldering using these handy alligator clip test leads. 10″ cables with an alligator clip on each end, color-coded.
You get 10 pieces in 5 colors. Strong and grippy, these always come in handy! We often use these in conjunction with a multimeter so we don’t have to hold the probes in place.
- 10-piece set, color-coded vinyl-covered crocodile/alligator clips.
- Contains two of each: Black, red, white, green, and yellow.
- 1 1/2″ alligator clips at both ends
Ring:bit V2 for micro:bit (expansion board only)
The Ring:bit expansion board is a simple PCB that extends the micro:bit’s 3 GPIO ports making them more convenient and easy to use in projects.
- This module converts the P0/P1/P2 port to the common GVS port.
- It can be loaded 3 AAA batteries to drive the car or other components.
With this board, you can transform your micro:bit into so much more. Build your own robot smart car and more.
