Flux Colophony Rosin Core 40g features:
Flux rosin, solid resin, neutral ph for a correct electronic welding.
- They do not cause corrosion of non-ferrous metals
- Does not cause short circuits
It melts with the temperature, spreading through the area to be welded and penetrating into the most difficult corners, cleans and prepares the surfaces and components to be welded, and facilitates the adhesion and fluidity of the tin, improving welding in electronics works.
Use a toothpick for the application. Do not apply in excess.
Security:
- Use in ventilated spaces. Do not inhale vapors that are released when welding
- Keep the pot tightly closed and out of the reach of children
- Do not eat. It is not toxic
- Rarely irritating to skin contact

Raspberry Pi HD Pi NoIR V2 camera board Raspberry Pi HD Pi NoIR camera board connects to any Raspberry Pi or Compute Module to create HD photos and video. The Pi NoIR (without infrared) is the same as the standard camera module but without an infrared filter. Therefore, it is excellent for photography and video in the dark.
The module uses Sony's IMX219PQ image sensor that offers high-speed, high-sensitivity video images.
The Pi NoIR module offers contamination from Reduced image such as fixed pattern noise and smudges. It also has automatic control functions such as exposure control, white balance and luminance detection. Raspberry Pi NoIR Camera Board, Sony IMX219 8 Megapixel Sensor features:
and benefits: No infrared filter
High quality images
