5V High / Low Level With Trigger Opto-Isolator 4 Channels Power Relay Module With For Argon NEO For Raspberry Pi 4 Case
2 PCS Electronic Accessories: 1 x Case for Raspberry Pi 4 & 1 x 4-channel Opto-isolator Power relay module
This is the latest Argon NEO for Raspberry Pi 4 case , which is made by robust aluminum alloy. It use aluminum-alloy injection metod so that stronger and more delicate and smooth than CNC process.
The most unique design is the magnetic sliding top cover - mormally the top cover is attached to the magnet and you can slide it out a bit when you need to to use the camera mount and POE, or slide it out completely to reveal the top. It will help to proof the dust and splashing liquid better.
Of course the case has heat dissipation for Raspberry Pi 4 by passive cooling ,with the silicone thermal pad and aluminum body.
