WeAct STM32U585CIU6 Core Mini – An $8 STM32U5 board supported by MicroPython v1.28

While checking out MicroPython v1.28 changelog, I noticed a board from WeAct Studio based on ST’s STM32U5 Cortex-M33 microcontroller: the WeAct STM32U585CIU6 Mini Core board (WEACTSTUDIO_MINI_STM32U585 in MicroPython code). I found it interesting/newsworthy, as while I had written about the initial STM32U5 MCU release in 2021, and followed up with beefier STM32U5 SKUs with NeoChrom 2.5D GPU and up to 4MB flash in 2023, we had yet to cover a third-party board based on an STM32U5 MCU, excluding the Arduino UNO Q SBC running Linux on a Qualcomm QRB2210 MPU and using an STM32U585 for real-time and I/O control. The WeAct STM32U585CIU6 Core Mini changes that as a low-cost, standalone STM32U5 MCU board. WeAct STM32U585CIU6 Core Mini specifications: Microcontroller – ST STM32U585CIU6 Core – Arm Cortex-M33 Armv8-M core clocked at up to 160 MHz with FPU, Arm TrustZone Memory – 768 KB RAM Flash – 2048 KB flash GPU – […]

$2 WeAct Display FS adds a 0.96-inch USB information display to your computer

WeAct Display FS is an inexpensive 0.96-inch USB display dongle designed to add an information display or a tiny secondary display to your computer or SBC. We’ve seen this type of information display with products such as the Turing Smart Screen, a larger 3.5-inch color display, or small OLEDs integrated into cases such as the Pironman 5 Max to disable text. The WeAct Display FS V1 may be tiny, but it’s also a full-color 160×80 resolution display that can be customized with software provided by WeAct. WeAct Display FS V1 specifications: Display – 0.96-inch RGB565 display with 160×80 resolution Host interface – “Reversible” USB 2.0 Type-A Full Speed (FS) port showing as a CDC device Dimensions – 43 x 14.5 mm Since you wouldn’t want to get a display only for it to face the wrong direction, for instance, the desk or the wall, the company made the USB-A port […]

WeAct RA4M1 – A small board with plenty of GPIOs that’s software-compatible with the Arduino UNO R4

Last week, we covered the Maker Go RA4M1-R4 development board, an inexpensive “clone” of the Arduino UNO R4 Minima with some small modifications like support for up to 50V DC input and a 3.3V/5V switch for I/Os. But today, I’ve come across a smaller and cheaper Renesas RA4M1 board that’s also software compatible with the Arduino UNO R4. Meet the WeAct RA4M1. The WeAct RA4M1 is mostly a breakout board for the Renesas R7FA4M1AB3CFM Arm Cortex-M4F microcontroller with two 30-pin GPIO headers, a USB-C port for power and programming, and three buttons. It offers a middle ground between the Arduino UNO R4 Minima and the tiny XIAO RA4M1 USB-C board.
