Raspberry Pi 500 review with Raspberry Pi Monitor and teardown

Raspberry Pi 500 review with Monitor Speaker

The Raspberry Pi 500 keyboard PC is just out along with the 15.6-inch Raspberry Pi Monitor and received samples from Raspberry Pi for review a few days ago.  I’ve had time to play with both, so in this review, I’ll go through an unboxing of the kit I received and report my experience with both the keyboard PC and monitor. Unboxing I received two packages. The first one with the Raspberry Pi Monitor, and the second with a Raspberry Pi 500 (UK layout), a 27W USB-C power adapter, and a micro HDMI to HDMI cable. So not quite a full Raspberry Pi 500 Desktop Kit since there’s no mouse and beginner’s manual but close to it. Let’s start with the keyboard PC. The bottom side of the package has some specs and a logo for the keyboard layout, in this case “UK”. There’s only the keyboard PC in the package. […]

Raspberry Pi 500 keyboard PC launched together with 15.6-inch Raspberry Pi Monitor

Raspberry Pi 500 and Monitor

The Raspberry Pi 500 keyboard PC is now available with the guts of a Raspberry Pi 5 including a Broadcom BCM2712 quad-core Cortex-A76 SoC, 8GB LPDDR4x and a 32GB microSD pre-loaded with Raspberry Pi OS. But the company also took the opportunity to launch the 15.6-inch Raspberry Pi Monitor that was first showcased at Embedded World 2024. That means Raspberry Pi launched 22 products this year including kits, and we’re promised that would be the last launch for 2024! But Pi fans can expect a small surprise in the first half of January… Raspberry Pi 500 keyboard PC Raspberry Pi 500 specifications: SoC – Broadcom BCM2712 CPU – Quad-core 64-bit Arm Cortex-A76 processor @ 2.4GHz GPU – VideoCore VII GPU with support for OpenGL ES 3.1 graphics, Vulkan 1.2 VPU – 4Kp60 HEVC decoder System Memory – 8GB LPDDR4X-4267 SDRAM Storage – 32GB microSD card preloaded with Raspberry Pi OS […]

$20 ATOMIC Display Base is a low-cost HDMI display driver for M5Stack’s ESP32-based Atom IoT controllers

M5Stack ATOMIC Display Base (GW1NR)

M5Stack has recently launched the M5Stack ATOMIC Display Base, an HDMI display driver designed to emulate traditional SPI TFT-LCD data output using Gowin GW1NR-9C FPGA and a built-in LT8618SX RGB-to-HDMI chip and designed to work with the company’s Atom IoT controller family based on ESP32 wireless microcontrollers. The module supports up to 720p (1280×720) image output with a 24-bit color depth and has an average frame rate of 12–16 FPS.
