Raspberry Pi’s RP2040 chip is designed for dirt cheap microcontroller boards like the Raspberry Pi Pico, which sells for as little as $4. With a 133 MHz dual-core ARM Cortex-M0+ processor and 264KB of memory, it’s clearly not designed to be a general-purpose computer. But folks have managed to build things like game consoles, pocket […]

Raspberry Pi Pico W SDK update brings initial Bluetooth support
The Raspberry Pi Pico W is a tiny $6 single-board computer with low-power RP2040 microcontroller and a wireless chip that supports WiFi 4 (802.11n) and Bluetooth 5.2. But when the Pico W launched last summer, only the WiFi was actually usable, since there was no software support for Bluetooth functionality. Now Raspberry Pi has released […]
Lilbits: LastPass customer data stolen (included encrypted password vaults) and what you can do about it
You probably know that you should have a unique, secure password for every site you visit (unless you’re already living in the post-password world of passkeys). You also probably know that there’s no way you’re going to remember all of those unique passwords, which is why we have password managers like 1Password, LastPass, Dashlane, Bitwarden, […]
Lilbits: Raspberry Pi Zero-like mini PCs compared, RP2040 microcontroller overclocked, and reducing the wait time for Purism’s Librem 5 Linux smartphones
The Raspberry Pi Zero and Raspberry Pi Zero 2 are incredibly small, cheap, and versatile single-board computers… but in a time of global supply chain shortages, they’re also kind of hard to get your hands on these days. But there are also a growing number of other tiny PCs competing in this space. And Bret Weber […]
The Poly Keyboard uses tiny OLED displays as keys (DIY, work in progress)
The Poly Keyboard is a DIY project to create a keyboard with tiny OLED displays beneath each key, allowing you to switch languages, layouts, or other functions via software. It’s been under development for a few years, but this month the creator of the project assembled the first functional prototype of the keyboard… or at […]
Roundy is a slick, low-cost way for makers to experiment with round displays (crowdfunding)
If you’ve been looking for a simple inexpensive way to prototype a project that utilizes a circular display, a new Kickstarter thing may offer the solution. Roundy is a 1.28 inch round LCD display connected to a small board powered by a low-power microcontroller. A Kickstarter campaign for Roundy just went live, and you can […]
Now you can buy a Raspberry Pi RP2040 microcontroller for $1
When the Raspberry Pi Foundation launched the RP2040 microcontroller earlier this year, the cheapest way to get your hands on one was to buy a $4 Raspberry Pi Pico board or a similar module powered by the MCU. Now you can buy the microcontroller itself as a standalone product for just $1. You can find […]
Lilbits: AYA Neo delayed (again), Samsung tablet leaked (again), and PlayStation movie & TV purchases and rentals are ending
The AYA Neo is a handheld gaming PC with a 7 inch, 1280 x 800 pixel touchscreen display surrounded by game controllers, an AMD Ryzen 5 4500U processor with Radeon Vega 6 graphics, 16GB of RAM, and a 512GB PCIe NVMe SSD. After shipping the first small batch of devices to customers in China, AYA […]
Raspberry Pi launches custom RP2040 microcontroller and $4 Raspberry Pi Pico board (plus 3rd-party hardware)
Nearly a decade after debuting its first $35 single-board computer, the Raspberry Pi Foundation is launching a new Raspberry Pi Pico that sells for just $4. It’s so small and so cheap that you get one free when you buy a copy of the February 2021 edition of HackSpace magazine. But the Raspberry Pi Pico isn’t […]
