Raspberry Pi 400: This $100 keyboard is a full-blown computer
Looking at the hardware, the Raspberry Pi 400 is effectively an optimized Raspberry Pi 4 Model B built into a keyboard. Students and tinkerers get a PC with a small footprint, a low price, and great possibilities.
It’s based on the Broadcom SoC BCM2711, a system-on-a-chip manufactured in 16nm with four Cortex-A72 cores and an increased clock rate compared to the Raspberry Pi 4B. It also offers 4GB LPDDR4-3200 and a VideoCore VI GPU, which is capable of OpenGL-ES 3.0 and the playback of video material in 4K/UHD with the help of H.265.
