Raspberry Pi, a company known for producing affordable single-board computers, has raised the prices of its 2 GB versions of the Raspberry Pi 4 and Raspberry Pi 5 by $12.50. The Raspberry Pi 4 with 2 GB of memory now costs $67.50, while the Raspberry Pi 5 with the same amount of memory is now priced at $77.50. These increases are attributed to higher production costs and a shortage of RAM, which has made the memory market tighter. In a previous update in April, Raspberry Pi kept prices stable for models with less memory, but now the company says it can no longer absorb additional costs for all models. This is the fourth price increase since December 1st. Other models in Raspberry Pi's lineup, such as the 1 GB versions of the Raspberry Pi 4 and 5, as well as the Compute Modules 4 and 5 with 2 GB of RAM, have not seen price changes. The company advises users to carefully assess their hardware needs before purchasing to avoid unnecessary costs. For users with limited performance requirements, Raspberry Pi suggests considering older models like the Raspberry Pi 3B, 3A+, or 3B+. Raspberry Pi also warns consumers against unauthorized resellers who may charge higher prices or sell non-compliant products. The company encourages buyers to use its network of authorized resellers for reliable purchases. The company notes that the current price changes are not final and plans to review and adjust prices once the memory market becomes more stable.
