Flipper Zero gets a Raspberry Pi RP2040-powered video game module

Flipper Zero hardware & wireless hacking tool can now be used as a proper game console thanks to a Raspberry Pi RP2040-powered video game module that mirrors the display of the device on a larger monitor or TV via DVI/HDMI video output, and also adds a 6-axis motion tracking sensor. The Flipper Zero has been in the news in recent days, notably with Canada’s government banning the device due to car theft (although it only seems feasible on older cars), and today the company has announced the launch of a video game module developed in collaboration with Raspberry Pi Ltd. Video game module specifications: MCU – Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller clocked up to 133 MHz with 264 kB SRAM Video Output – DVI-D at 640х480 with 60 Hz refresh rate. It also supports HDMI. USB – USB Type-C port connected to the microcontroller. Acts as a USB device […]

EVN Alpha is a LEGO-compatible robotics controller built around Raspberry Pi RP2040 MCU (Crowdfunding)

The EVN Alpha is a robotics project from a team based in Singapore and is aimed at roboticists seeking an advanced building platform beyond what LEGO Robotics kits offer. This robotics controller can be considered a spiritual successor to the LEGO MINDSTORMS EV3 intelligent brick. It runs on the Raspberry Pi RP2040 microcontroller with two Cortex M0+ cores running at a maximum clock speed of 133 MHz and 264KB of embedded SRAM and builds upon the rich software support available for the microcontroller. It features 64 LEGO Technic-compatible holes on five sides for easy installation into your projects and has 26 ports for I2C, UART, servos, EV3, and NXT motors. It is smaller volumetrically than the LEGO bricks and can be powered from two generic 18650 Lithium-ion cells rather than a proprietary solution (unlike the LEGO SPIKE Prime). The EVN Alpha was created as a “basecamp for students looking to […]

SB’s Dual Roundy and Squary Displays are powered by RP2040 or ESP32-S3 microcontrollers (Crowdfunding)

Dual Display Modules Roundy and Squary by SB Components

SB-Components has launched Dual Roundy and Dual Squary display modules powered by Raspberry Pi RP2040 or ESP32-S3 microcontrollers. These compact modules feature a 6-DoF IMU, interchangeable displays, and multiple storage and connectivity options. The Dual Roundy is equipped with two 1.28-inch round displays, with a 240 x 240 resolution, and uses the GC9A01 display driver IC. In contrast, the Dual Squary features two 1.54-inch square displays with a 240 x 240 resolution but utilizes the ST7789 display driver. Both displays offer a choice between a Raspberry Pi RP2040 MCU and the ESP32-S3-WROOM-1 module catering to different needs in performance and wireless capabilities. We’ve previously explored other rounded displays like the MaTouch ESP32-S3, T-RGB ESP32-S3, and ESP32-S3 Round SPI TFT. We’ve also examined other products from SB Components such as the Cluster HAT, PiMecha, PiTalk 3G HAT, and Micro RP2040. Feel free to check these out for more interesting tech insights. […]

2023 Year in review – Top 10 posts, statistics, and what to expect in 2024

It’s the last day and last article of the year, so we will look at some highlights of 2023, some traffic statistics on the CNX Software website, and speculate what interesting developments may happen in 2024. Looking back at 2023 The semiconductor shortage that had happened since 2020 started to fade away in early 2023, and supplies for most electronics components and devices seem to be adequate at this time, so that was a bright spot this year, and hopefully, it will stay that way in 2024 despite geopolitical tensions. We did not have any super exciting new Arm application processors from Rockchip, Amlogic, or Allwinner announced this year, although the Amlogic S928X penta-core Cortex-A76/A55 CPU started to show up in some 8K TV boxes. The launch of the Raspberry Pi 5 SBC with a Broadcom BCM2712 quad-core Cortex-A76 processor was probably the main highlight for Arm on this side […]

Raspberry Breadstick – A RP2040-based development board in a quirky form factor

The Raspberry Breadstick is a breadstick-shaped development board that is designed for ease of use. Unlike other development boards, the Breadstick is built to fit directly on your breadboard and interface with the other electronic components in your project without the need for lengthy jumper wires. It serves to deliver a prototype that is neat, straightforward, and easy to troubleshoot. It is based on Raspberry Pi’s debut microcontroller, the RP2040, which is the same MCU chip that powers the Raspberry Pi Pico and several other boards. We recently covered the Waveshare RP2040-PiZero that comes in the Pi Zero’s form factor. The RP2040 is cheap and supports C/C++, MicroPython, and CircuitPython. The Breadstick has other interesting features such as a lineup of 24 addressable RGB LEDs with fast refresh rates, a 6-axis inertial measurement unit for collecting acceleration and rotation data, as well as 16MB of external flash storage for your […]

Microflex MCUs – Tiny USB development boards based on ESP32-S3, ESP32-S2, ESP32-C3, ESP32-C6, or Raspberry Pi RP2040 (Crowdfunding)

Microflex MCU board with ESP32 and RP2040 microcontrollers

SB Components is back with yet another crowdfunding campaign this time with the Microflex MCUs USB development boards all with the same tiny form factor and offered with a choice of five microcontrollers namely Raspberry Pi RP2040, ESP32-S3, ESP32-S2, ESP32-C3, or ESP32-C6. Microflex MCUs share the same layout with a USB-C port for power and programming, a built-in RGB LED, two buttons for Boot and Reset/User, and two rows of 10-pin with through and castellated holes to access the GPIOs and power signals such as 5V, 3.3V, and GND. But they differ in terms of the processor used, wireless features, and available I/Os as shown in the table below which sadly lacks any information about the flash and eventual PSRAM… The illustration below includes some more details for the Micro-C6 with the main components, ports, and a pinout diagram. Programming the firmware for the ESP32-series can be done through the […]
