+
+The Raspberry Pi Bumper for Raspberry Pi 5 is a snap-on silicone cover that protects
+the bottom and edges of the board. When attached, the mounting holes of the Raspberry Pi remain accessible through the bumper.
+
+The Bumper is only compatible with Raspberry Pi 5.
+
+== Assembly instructions
+

 NOTE: There is https://github.com/raspberrypi/libcamera/issues/43[some evidence] to suggest that the Camera Module 3 may emit RFI at a harmonic of the CSI clock rate. This RFI is in a range to interfere with GPS L1 frequencies (1575 MHz). Please see the https://github.com/raspberrypi/libcamera/issues/43[thread on Github] for details and proposed workarounds.

+.A 64GB Raspberry Pi SD Card
+image::images/sd-cards.jpg[width="80%"]
+
+SD card quality is a critical factor in determining the overall user experience for a Raspberry Pi computer. Slow bus speeds and lack of command queueing can reduce the performance of even the most powerful Raspberry Pi models.
+
+Raspberry Pi's official microSD cards support DDR50 and SDR104 bus speeds. Additionally, Raspberry Pi SD cards support the command queueing (CQ) extension, which permits some pipelining of random read operations, ensuring optimal performance.
+
+You can even buy Raspberry Pi SD cards pre-programmed with the latest version of Raspberry Pi OS.
+
+Raspberry Pi SD cards are available in the following sizes:
+
+* 32GB
+* 64GB
+* 128GB
+
+== Specifications
+
+Raspberry Pi SD cards have the following specifications:
+
+Speed Class: C10, U3, V30, A2
+
+Random 4KB read performance:
+
+* 3,200 IOPS on Raspberry Pi 4 (DDR50)
+* 5,000 IOPS on Raspberry Pi 5 (SDR104)
+
+Random 4K write performance:
+
+* 1,200 IOPS on Raspberry Pi 4 (DDR50)
+* 2,000 IOPS on Raspberry Pi 5 (SDR104)
+
+Form factor: microSDHC/microSDXC
+
+SD specification: SD6.1
