It includes a 1.008 GHz C907 core, 8MB or 16MB PSRAM, SPI NOR flash, microSD storage, USB-C, and GPIO expansion, with support for Linux, Buildroot, and Zephyr RTOS. ### Source excerpt YuzukiHD has made another open-source hardware Linux SBC. YuzukiNeko is a Raspberry Pi Pico-sized single board computer powered by a new Allwinner F101 RISC-V SoC. The Allwinner F101 processor features a single 1.008 GHz C907 RISC-V core, 8MB or 16 MB PSRAM, and support for various display interfaces such as MIPI DSI, 24-bit RGB, and LVDS. The YuzukiNeko board itself features the F101 SoC, an SPI NOR flash, a microSD card for storage, a USB-C port, and two 20-pin GPIO headers. YuzukiNeko specifications: SoC - Allwinner F101 CPU - T-head C907 RISC-V core up to 1.008 GHz Memory - 8MB or 16MB PSRAM @ 252 MHz Package - QFN-68 Storage 128 Mbit NOR flash (PY25Q128HA-SUH-IT) MicroSD card slot USB - USB Type-C port for data, power, and programming Expansion 2x 20-pin expansion headers with GPIOs, ADC, 5V, 3.3V, and GND 5x pads with HP out (analog speaker output) and four [...] The post YuzukiNeko - A Linux-capable Allwinner F101 RISC-V SBC with Raspberry Pi Pico form factor appeared first on CNX Software - Embedded Systems News. ## 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 ## Enabling External PSRAM for Zephyr Applications on ESP32 SoCs DevFeed: [Enabling External PSRAM for Zephyr Applications on ESP32 SoCs]() Original publisher: [Read original article]() Author: John Lee Published: 2024-12-30T00:00:00Z Content type: tutorial Language: en Sources: [Blog on Developer Portal]() Topics: [ESP32](), [Espressif]() Tags: [article](), [blog](), [devices](), [embedded](), [esp32](), [esp32-s2](), [esp32-s3](), [espressif](), [how-to](), [psram](), [spiram](), [zephyr]() ### AI overview This tutorial explains how to configure Zephyr applications to use external PSRAM on ESP32 modules. It covers dynamic memory allocation, adding PSRAM to the ESP32 memory map, and running code from PSRAM instead of Flash. ### Source excerpt This article presents ideas and suggestions on different scenarios to use the PSRAM available in some Espressif devices. ## Espressif Announces AWS IoT ExpressLink Modules Based on ESP32-C3 DevFeed: [Espressif Announces AWS IoT ExpressLink Modules Based on ESP32-C3]() Original publisher: [Read original article]() Author: John Lee Published: 2021-11-30T00:00:00Z Content type: article Language: en Sources: [Blog on Developer Portal]() Topics: [ESP32-C3](), [Amazon Web Services](), [Espressif](), [Internet of things](), [Bluetooth](), [Wi-Fi](), [ESP32]() Tags: [announce](), [authentication](), [aws](), [aws-iot](), [blog](), [bluetooth-le](), [digital-signature](), [esp32-c3](), [esp32-s3](), [espressif](), [flash-encryption](), [iot](), [messaging](), [newsletter](), [ota](), [provisioning](), [psram](), [secure-boot](), [security](), [wi-fi]() ### AI overview Espressif announces AWS IoT ExpressLink modules based on the ESP32-C3 SoC, with Wi-Fi and Bluetooth LE 5.0 connectivity, a serial interface for AWS IoT services, and pre-provisioned security features. ### Source excerpt Hi everyone, Espressif is proud to announce the availability of new Wi-Fi modules implementing the AWS IoT ExpressLink specification.
