CNX Software ☛ Raspberry Pi 4 dual RAM variant introduced to mitigate RAM price increases and supply challenges
Desperate times call for desperate measures. Raspberry Pi has decided to introduce a dual RAM variant of the Raspberry Pi 4 to allow DRAM supply chain flexibility along with manufacturing process improvement using intrusive reflow soldering. As you may remember, Raspberry Pi first increased the price of most Raspberry Pi 4/5 boards last December while launching the Raspberry Pi 5 1GB RAM to offer a $45 option.
