Q: What are the requirements of the RAM and SSD to assemble an ORS?

A:

Ram requirements

• Industrial operating temperature: -20°C to +85°C ( minimum temperature is probably not that important, we previously chose RAM with 0°C)
• SO DIMM 260 pin RAM
• At least 4G of RAM
• DDR4
• Operating supply voltage: 1.2V (should be standard for DDR4, check with Jean-Marc if different)
• Price in 2021: ~ 40 / 50 euros

• 2021: MTA4ATF51264HZ
• < 2020: SQR-SD4M-4G2K1SNB SODIMM DDR4 2133 4GB -20-85°C

SSD requirements 

• 32G at least
• mSATA
• Industrial operating temperature
