The issue cannot be fixed by users because the MCU must be flashed at the factory; corrected batches are planned, but their production timing is unknown. ### Source excerpt Hey everyone, we'd like to make a public disclosure to the community about a product currently selling on the PineStore website (pine64.com). The current Desktop PinePower V2 batch has an issue where in some situations the USB-C ports will report "0V" when there is obviously something attached. In reality it is actually outputting the correct voltage. This has been fixed for future batches, but the current batch still has stock available. There is no fix available for affected Desktop PinePower V2 batches as the MCU can only be flashed at the factory. We have no ETA when the fixed batch will start production as this depends on the rest of the buggered batch being sold. We'll let you all know when the fixed ones hit the store. And please don't open your PinePower devices as they're high voltage power supplies, which can lead to serious risks. ## Introduction to the PineTime Pro DevFeed: [Introduction to the PineTime Pro]() Original publisher: [Read original article]() Published: 2026-03-28T00:00:00Z Content type: article Language: en Sources: [Community blog on PINE64]() Topics: [Hardware](), [Microcontroller](), [SOC](), [Bluetooth](), [Embedded Software Dev](), [Development]() Tags: [bluetooth](), [embedded](), [firmware](), [fosdem](), [hardware](), [mcu](), [pinetime](), [pinetime-pro](), [psram](), [soc]() ### AI overview Pine64 introduces the PineTime Pro, a more powerful sibling to the original PineTime rather than a replacement. The prototype features a dual-core Cortex-M33 SoC, Bluetooth 5.2, expanded memory, an AMOLED touchscreen, GPS, health sensors, and other upgraded hardware. ### Source excerpt Table of contents Introducing the PineTime Pro Why "Pro" and not "PineTime 2" What makes it "Pro" A long road to get here Recent progress What about software? What happens next? Do you have something to share? Contact Community PineStore Introducing the PineTime Pro The PineTime Pro was officially announced at FOSDEM26 on the Pine64 stand. The demo was a bit modest (more on that later on), but we were delighted to showcase the first prototype of the "next generation PineTime" along with a demo running on a development board! We also mentioned the PineTime Pro in the FOSDEM 2026 Update blog post. In this blog post, we would like to provide a more in-depth look at the PineTime Pro. Why "Pro" and not "PineTime 2" The PineTime project started in October 2019, that's more than 6 years ago! Needless to say, the PineTime has been a great success. The community has been very active in developing firmware for the device, companion apps, tools and more. And, according to PineStore, it sells very well. The reason the PineTime Pro isn't called the PineTime 2 is because it's not meant to replace the original PineTime. The original watch still has a lot going for it: it is simple, hackable, efficient and already supported by great community projects like InfiniTime and WaspOS. It will continue production alongside this new model. The PineTime Pro should be seen as a more powerful, more feature-rich sibling rather than a direct successor. If the original PineTime is a solid open smartwatch platform, the PineTime Pro is our attempt to push that idea much further with new and improved components. What makes it "Pro" Compared to the "OG" PineTime, the PineTime Pro brings a significant hardware upgrade. At its core is a dual-core Cortex-M33 SoC, with one application core running at up to 200 MHz and a dedicated Bluetooth core. It also comes with 800 KB of internal SRAM and 8 MB of PSRAM. Around that MCU, the hardware currently includes: Bluetooth 5.2 - Classic (BR/EDR) & Low Energy A ## Error Handling in C, Go, Rust, and Google's Absl DevFeed: [Error Handling in C, Go, Rust, and Google's Absl]() Original publisher: [Read original article]() Author: Nevin Zheng Published: 2026-02-28T00:00:00Z Content type: opinion Language: en Sources: [nevzheng]() Topics: [Error Handling](), [Programming](), [Embedded Systems](), [Microcontroller](), [C](), [Go Language](), [Rust](), [Hardware]() Tags: [c](), [embedded](), [embedded-systems](), [error-handling](), [errors](), [go](), [hardware](), [microcontrollers](), [opinions](), [rust](), [stm32]() ### AI overview An opinionated survey of error handling across C, Go, Rust, and Google's Absl.

The article describes its firmware and server customization, tile-based display service, Liquid templating, and a Go program on Cloud Run that displays family calendar events. It also notes refresh-scheduling difficulties and the device's relatively high cost. ### Source excerpt The TRMNL is an 800x600, 1-bit e-ink display connected to a battery and a microcontroller, all housed in a nice but unremarkable plastic case. Because the microcontroller spends the vast majority of the time sleeping, and because e-ink displays don't require power unless they're updating, the battery can last six or more months. It charges over USB-C. When the microcontroller wakes up, it connects to a Wi-Fi network and communicates with a pre-configured server to fetch an 800x600 image to display, and the duration of the next sleep. You can flash your own firmware on the device, or point the standard firmware at a custom server. The company provides an example server, although you can implement the (HTTP-based) protocol in whatever way you wish. I considered running my own server, but thought I would give the easy path a try first to see if it would suffice. The default service lets you split the display into several tiles, and there are a number of pre-built and community-built things that can display in each. None of them worked well for me, but that's okay because you can create your own private ones. They get data either by polling a given URL, or by having data posted to a webhook. The layout is rendered using the Liquid templating system, which I had not used before, but it's reasonably straightforward. I wrote a Go program hosted on Cloud Run which fetches the family shared calendar and converts events from the next week into a JSON format designed to make it trivial to render in the templating system. With a 3D-printed holder, super glue, and some magnets, it's now happily stuck to the fridge where it displays the current date and the family events for the next week. The most awkward part of the default service is managing the refreshes. The device has a sleep schedule, and so do the tiles, which are only updated periodically. So the combination can easily leave the wrong day showing. It would be helpful if the service told you when the device would next up ## Espressif's ESP32-C5 is Now in Mass Production DevFeed: [Espressif's ESP32-C5 is Now in Mass Production]() Original publisher: [Read original article]() Author: John Lee Published: 2025-05-23T00:00:00Z Content type: release Language: en Sources: [Blog on Developer Portal]() Topics: [ESP32-C5](), [Espressif](), [RISC-V](), [SOC](), [ESP-IDF](), [Microcontroller](), [Internet of things]() Tags: [802-15-4](), [blog](), [bluetooth](), [esp-hosted](), [esp-idf](), [esp32-c5](), [espressif](), [iot](), [mcu](), [production](), [risc-v](), [security](), [soc](), [wi-fi-6](), [zigbee]() ### AI overview Espressif announces that its ESP32-C5 RISC-V SoC is now in mass production.
