• Rockchip based SBC features PoE connector and M.2 SATA support

  The URVE Board Pi is a Single Board Computer based on the 4-core Rockchip RK3566. This SBC comes with 2GB RAM, 8GB of eMMC, dual displays support, dual band Wi-Fi, BT 4.2, 1x GbE LAN, 1x M.2 slot for SSD and many other peripherals.

• Decoding 433 MHz Signals With Arduino & Raspberry Pi

  433 MHz radio signals are all around us. They’re used for things like smart power plugs, garage door openers, and home weather stations. Decoding these signals can allow you to interface and work with these devices on your own terms. To help in those efforts, [Joonas Pihlajamaa] has written a three-part tutorial on decoding these signals.

• Find us and your fellow Raspberry Pi enthusiasts at an event near you

  On the new website, you’ll notice there are a bunch of virtual and in-person events coming up soon, so head on over and hopefully you can find an event near you. You can also subscribe via RSS or iCalendar feeds so that you can keep tabs on new events as they’re posted.

• Puya PY32: The Cheapest Flash Microcontroller You Can Buy Is Actually An ARM Cortex-M0+

  There’s a bit of a contest going on when it comes to which is the cheapest microcontroller, yet most of the really cheap ones have one big trade-off in that they have one-time programmable (OTP) memory, generally requiring the use of an (expensive) device emulator during development. This raises the question of what the cheapest reprogrammable MCU is, which [Jay Carlson] postulates is found in the Puya PY32 ARM Cortex-M0+ based series.

• Moving my PC into my rack in a 2U case

  This week I finally moved my gaming/Linux PC into my little office rack—it's that 2U box above the UPS at the bottom: [...]

  I remembered seeing Linus Tech Tips' 4U build in a video a couple years ago—but he has a full 42U rack in his basement. I don't have that much space—just 2U (technically 3U if I wanted) in my little under-desk studio rack.

• Raspberry Pi Zero 2 W Powers Budget Friendly NAS

  Building a Raspberry Pi powered NAS (Network Attached Storage) is one of the earliest projects achieved with the board. There was something about the $35 board back in 2012 that screamed "build a NAS", probably that it was running a Linux OS. You can spend big on a great NAS setup, you can spend smart on a kit such as the Argo EON, or you can spend little and build your own. The latter is what Michael Klements has achieved, a $35 Raspberry Pi Zero 2 W powered NAS in a custom 3D printed case.
