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 […]

Infineon launches PSoC Edge Cortex-M55/M33 microcontrollers for enhanced AI and ML applications

The PSoC Edge microcontrollers integrate the Arm Cortex-M55 core with Helium DSP and the Ethos U55 NPU unit for advanced AI tasks. It also includes a power-efficient Arm Cortex-M33 core paired with an NNLite(DSP/NPU) for simpler AI tasks.

Infineon’s new PSoC Edge series of microcontrollers integrates the Arm Cortex-M55 core with Helium DSP and the Ethos U55 NPU unit for advanced AI tasks. It also includes a power-efficient Arm Cortex-M33 core paired with an NNLite(DSP/NPU) for simpler AI tasks. This setup allows the device to be more efficient in varying load conditions. Infineon’s PSoC lineup is a configurable microcontroller powered by Arm Cortex-M4, Cortex-M3, or Cortex-M0+ cores. The main USP (Unique Selling Point) of this lineup is its configurable digital and analog components. This feature makes them somewhat similar to an FPGA, but an FPGA is far more difficult to program than these microcontrollers and they are also very power-hungry. The device is equipped with advanced HMI and “Always-on” capability. “Always-on” is a feature of this device to constantly monitors and responds to signals automatically, making it suitable for smart homes, security, wearables, robotics, and many more.
