  "textContent": "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 display, and basic HRM and accelerometer. The PineTime Pro is a massive upgrade that should support a wider range of firmware. PineTime Pro specifications: SoC – Unnamed wireless MCU CPU – Arm Cortex-M33 MCU @ up to 200 MHz Memory – 800 KB SRAM Wireless – Bluetooth 5.2 Classic (BR/EDR) & Low Energy (additional Cortex-M33) Memory – 8 MB PSRAM [...]\n\nThe post PineTime Pro smartwatch to feature dual-core Cortex-M33 MCU, 2.13-inch AMOLED, GPS, and more appeared first on CNX Software - Embedded Systems News.",
