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

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

Mini review of the ThinkNode M6 “outdoor solar power for Meshtastic”

Mini review of the ThinkNode M6 “outdoor solar power for Meshtastic”

Elecrow has sent us a solar-powered ThinkNode M6 Meshtastic device for review. Last year, I reviewed the ThinkNode M1 and M2 Meshtastic nodes, and I was a bit disappointed by the point-to-point range in a suburban environment, where I got about 550 meters of range after switching to LONG SLOW mode. Nine months have passed since that review, and there still doesn't seem to be any Meshtastic community in the second-largest city in Thailand, probably because typical Meshtastic terminals are more expensive than entry-level Android smartphones, have limited functionality, and the mobile app is still a mess despite a revamp. Nevertheless, when Elecrow asked me whether I wanted to test the "ThinkNode M6 outdoor solar power for Meshtastic", I thought it might be fun. The main purpose of this mini review is to check the range I get using the M6 as a router between the M1 and M2 nodes.

When it comes to #IoT protocols there are two main options: #BLE vs #openthread.

While openthread is mainly focused in industrial applications, BLE has massive commercial appeal. Because of this BLE is a rapidly progressing tech comparatively, and superior in terms of speed and reliability.

While BLE goes to 2 Mbit/s, openthread delivers 250kbps. Considering IoT applications are #lowpower nodes, this high throughput helps quick transmissions and save power.

On the other hand, openthread boasts native #ipv6 access, only requiring a "border router".

And as it needs a openthread border router device anyway - IMO we might as well write and put a relay app in it, taking away openthread's advantage...

DFRobot launches low-power, low-cost Fermion: BMV080 air quality sensor module

https://fed.brid.gy/r/https://www.cnx-software.com/2026/03/06/dfrobot-low-power-low-cost-fermion-bmv080-air-quality-sensor-module/

DFRobot launches low-power, low-cost Fermion: BMV080 air quality sensor module

Just last year, we reported on the SparkFun Air Quality PM1/PM2.5/PM10 Sensor, based on the Bosch BMV080 fanless air-quality sensor and priced at around $65. DFRobot has now launched a low-cost alternative, the Fermion: BMV080, which provides the same fanless, laboratory-grade PM1, PM2.5, and PM10 sensing capabilities for just $29.90. The sensor uses laser-based light-scattering technology with fanless optical counting to detect particles as small as 0.5 μm. This avoids fan noise, dust buildup, and mechanical wear, which are common with fan-based PM sensors, and, on top of that, it has a service life of up to 10 years. It measures particulate concentrations in a 0–1000 μg/m³ range with 1 μg/m³ resolution and ±10 μg/m³ of accuracy. The sensor supports I2C and SPI interfaces, and consumes about 70 mA in continuous measurement mode with a 6 μA sleep current, making it suitable for battery-powered systems.
