Black box with cooling fan and heatsinks for Raspberry Pi 4 model B

This RAB Holder is not only compatible with Raspberry Pi 3 B+ / Raspberry Pi 3 Model B / 2 Model B / B+, but also suitable for Arduino Uno, Mega2560, 400 Tie-Point and 830 Point breadboards. 

Arduino UNO is the best board to start your experience with electronics and programming. If this is your first experience with the platform, UNO is the most robust board you can start with. UNO is the most widely used and documented board in the entire Arduino family. Its power ensures ATmega 328p microcontroller, the board is equipped with 14 digital pins, and 6 analog

This thread is designed to be used in Wearables projects because it provides a very firm grip on the fabric to be sewn.
What differentiates this thread from another thread is the fact that it is actually spun from this stainless steel fiber. This means that while it may not be easy to weld since it is steel, it also does not burn when you touch it with a soldering iron.
It is suitable for sewing machine (like a bobbin thread) it is particularly tense, which means that it firmly grasps the fabric and is not slippery. Lilypad Matching Conductive Sewing Thread Wearable features:
- Stainless steel fibers
- Resistance: 700 Ohm / m
- Thin and strong thread
- Includes 1 meter of wire
