PineTime Pro smartwatch to feature dual-core Cortex-M33 MCU, 2.13-inch AMOLED, GPS, and more

PineTime Pro

Pine64 has announced progress on the PineTime Pro smartwatch, powered by a dual-core Cortex-M33 microcontroller with Bluetooth 5.2 Classic and LE and 800KB SRAM. The watch also features a 2.13-inch AMOLED display, GPS support, a heart rate monitor, and a 6-axis motion sensor. It’s an upgrade to the PineTime project unveiled in September 2019, and one of the most popular Pine64 devices thanks to open-source software projects such as InfiniTime firmware. For reference, the PineTime ships with a Nordic nRF52 Arm Cortex-M4 Bluetooth MCU with 64 KB SRAM, a 1.3-inch IPS display, and basic HRM and accelerometer. The PineTime Pro is a massive upgrade that should support a wider range of firmware.

SparkFun Thing Plus – ESP32-C5 board offers dual-band WiFi 6, Adafruit Feather pinout, LiPo battery support

SparkFun Thing Plus ESP32 C5

Espressif has recently released the ESP-IDF v6.0 framework with support for ESP32-C5 and ESP32-C61, so we can expect more ESP32-C5 boards. Following the launch of boards like DFRobot FireBeetle 2 and the Espressif DevKitC-1, SparkFun has now launched its Thing Plus – ESP32-C5, an Adafruit Feather-compatible board based on the ESP32-C5. The timing is no coincidence. Although the ESP32-C5 dual-band WiFi 6 SoC was announced back in 2022, hardware makers have been waiting for stable software support. With the release of ESP-IDF v6.0, the ESP32-C5 moves from “preview” to “stable” and adds key features, such as Safe Bootloader OTA updates. This enables the ROM bootloader to fall back to a recovery partition if an update fails, making it reliable enough for companies like SparkFun to launch hardware for remote deployments and Matter-compatible smart home applications.

ESP-IDF v6.0 framework adds support for ESP32-C5 and ESP32-C61, preview for ESP32-H21 and ESP32-H4

ESP-IDF Release v6.0

Espressif Systems released the ESP-IDF v6.0 framework a few days ago with stable support for ESP32-C5 and ESP32-C61 SoCs, as well as preview support for ESP32-H21 and ESP32-H4 low-power wireless microcontrollers. The framework also implements a new ESP-IDF Installation Manager (EIM) to make the ESP-IDF installation easier, relies on the low-footprint Picolibc C library, adds security and tooling updates, as well as a few Wi-Fi enhancements, and the ability to update the bootloader over the air. Here are some of the ESP-IDF v6.0 highlights: ESP-IDF Installation Manager – Unified cross-platform tool to simplify the setup process for ESP-IDF and compatible IDEs. It’s available as a graphical interface or a CLI for automation and CI/CD pipelines. You can check the installation instructions for your OS. Picolibc replaces Newlib for a smaller memory footprint and better performance on resource-constrained devices. Check the Newlib vs Picolibc comparison for details. Contrary to some of […]

Enabling MediaTek M7902 WiFi and Bluetooth drivers on Ubuntu 24.04 the easy way

Mediatek MT7902 Linux

Last month, we noted that Mediatek MT7902 WiFi 6E and Bluetooth 5.x chipset finally got drivers in mainline Linux, and should be part of the Linux 7.0 release. MT7902 wireless modules are used in many Windows laptops, but users have been asking for the Linux drivers for almost two years now. One method is to wait for the drivers to find their way into your distribution, but “hmtheyboy154” didn’t feel like waiting and backported the drivers to Linux 6.6 to 6.19. Since I own one of those laptops, namely the ASUS Vivobook 16, I gave it a try on Ubuntu 24.04, but it should work on other Linux distributions as well. Note that this method only works with the PCIe driver, so if you own an SDIO module, you’d need to work out another solution. My Ubuntu 24.04 laptop is indeed using an MT7902 PCIe module (AW-XB552NF):

I could […]
