M5Stack CoreS3 SE cost-down ESP32-S3 IoT controller features a 2-inch touch display, a microSD card slot, a speaker, two microphones

M5Stack CoreS3 SE ESP32-S3 IoT controller

The M5Stack CoreS3 SE, also called M5CoreS3 SE, is a cost-down version of the M5Stack CoreS3 IoT controller based on the ESP32-S3 wireless microcontroller with a 2-inch capacitive touch display, a microSD card slot, a USB-C port, a speaker, two microphones, and one Grove connector for expansion. The M5Core S3 SE loses the DIN Base so the associate features are gone and DIN rail mounting is not possible by default anymore. That also means the M5Stack CoreS3 SE controller is about twice as thin, and the color is also different (medium grey vs black grey). Major internal changes include the removal of the camera and the three sensors found in the original model. M5Stack CoreS3 SE specifications with highlights in bold and strikethrough showing differences against the CoreS3 model: Wireless MCU – Espressif Systems ESP32-S3FN16R8 CPU – Dual-core 32-bit Xtensa LX7 microcontroller with AI vector instructions up to 240MHz, RISC-V […]

Inkplate 6 MOTION STM32-powered wireless e-paper display offers higher resolution and faster refresh rates (Crowdfunding)

Inkplate 6 MOTION with enclosure

The Inkplate 6 MOTION is a new product from Soldered Electronics in their Inkplate series of wireless e-paper displays. It is a 6-inch e-paper display with a partial refresh rate of 11fps which reduces obvious latency in rendering dynamic content such as videos, animations, and scrolling text. The display is driven by an STMicroelectronics dual-core STM32H743 microcontroller, with an ESP32-C3 as a secondary processor. It features Wi-Fi and Bluetooth for networking and a host of peripheral interfaces for physical connectivity. It includes several sensors such as a rotary encoder for quick navigation, a gravitational accelerometer with a gyroscope for tracking device orientation, and a motion detection sensor. We covered the original Inkplate 6 display when it launched on Crowd Supply in 2019. The Inkplate 6 is much less expensive than the new model but has a lower screen resolution (800 x 600 px) and slower refresh rates (256ms). Furthermore, it […]

ESP32-S3-Matrix board features 64 LEDs, GPIO pins, 9-axis “attitude” sensor for robotics and motion control applications

Waveshare ESP32 S3 Matrix board

The Waveshare ESP32-S3-Matrix is a microcontroller development board designed for AIoT applications, featuring a larger 8×8 RGB LED matrix (64 LEDs) compared to the 5×5 RGB LED matrix (25 LEDs) on the ESP32-C3/ESP32 based “C3FH4 RGB” / “PICO D4 RGB” board. In addition to that the Waveshare board features two 10-headers for GPIOs, UART, and power signals, along with an integrated QMI8658C attitude sensor (9-axis IMU sensor), making it ideal for robotics and motion control projects. Recently we have seen Waveshare introduce affordable products that are perfect for embedded development like the $15 1.69-inch IPS touch LCD module, the $6.99 ESP32-C6-Pico Board, the $4.99 ESP32-S3-Tiny board and much more feel free to check those out if you are interested in those. Waveshare ESP32-S3-Matrix dev board specifications: MCU – Espressif Systems ESP32-S3FH4R2 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, […]

Enabling Zigbee in Bluetooth LE temperature and humidity monitors from Xiaomi and Qingping using Telink TLSR8258 WiSoC

XIaomi temperature humidity monitors Zigbee

Qingping CGDK2 and Xiaomi LYWSD03MMC Bluetooth LE (BLE) temperature and humidity monitors based on Telink TLSR8258 can be switched to Zigbee thanks to a custom firmware flashed over-the-air. Telink TLS8258 is a multi-protocol wireless microcontroller supporting Bluetooth LE 5, Bluetooth Mesh, Zigbee, RF4CE, Thread, 6LoWPAN, HomeKit, ANT, and 2.4GHz proprietary and found in boards such as the LILYGO T-Zigbee and various products. Some products only enable one wireless protocol, for example, Bluetooth LE as in the just-mentioned Qingping and Xiaomi monitors, but “SmartHomeScene” has found out that it was possible to switch from BLE to Zigbee on those by simply updating the firmware. The Telink TLS8258 devices mentioned above will publish data over BLE every 10 minutes (unless humidity or temperature changes, in which case data is transmitted immediately) with the default firmware, but Zigbee can be enabled by using the pvvx custom firmware for the following models: Xiaomi LYWSD03MMC […]

GEEKOM XT12 Pro Ubuntu 24.04 review

We’ve already looked at GEEKOM XT12 Pro specifications and hardware design in the first part of the review and followed up by reviewing the Intel Core i9-12900 mini PC with Windows 11 Pro in the second part. We’ve now had time to review the GEEKOM XT12 Pro mini PC with the just-released Ubuntu 24.04 operating system to evaluate the compatibility and performance in Linux. In this third and final part of the review, we’ll test features in detail, evaluate performance with benchmarks, test storage and network capabilities, check YouTube video playback at 4K and 8K resolution, perform a stress test to check the cooling solution and provide numbers for fan noise and power consumption of the GEEKOM XT12 Pro mini PC. Ubuntu 24.04 installation and system information We’ve resized the Windows 11 by half in order to install Ubuntu 24.04 in dual boot configuration. After that, we inserted a USB […]
