TASMOTA Now Supports ESP32 Targets including some Ethernet and Camera Boards

Tasmota ESP32

TASMOTA now supports ESP32. The open-source firmware was initially designed for ESP8266 and ESP8285 based Sonoff home automation devices providing an alternative to eWelink firmware with support for MQTT protocol allowing integration with home automation frameworks like Domoticz or openHAB. It has since then expanded to support hardware from various brands, but until recently you were still limited to products with ESP8266 or ESP8285, and the good news is that TASMOTA has now gotten experimental support for ESP32 boards and products such as TTGO T-Camera. You’ll find basic documentation and well as Tasmota ESP32 (aka Tasmota32) firmware files for LilyGO TTGO T-Camera board, displays, and I2C sensor on Tasmota Github.io website. The ESP32 port is based on Jörg Schüler-Maroldt’s work. PuceBacoon also found other ESP32 boards in the source code including Olimex ESP32-PoE board in xdrv_82_ethernet.ino file and “AI Thinker” cameras in xdrv_81_webcam.ino. If you’d like to give it a […]

Raspberry Pi VideoCore IV Boards Get an Unofficial Vulkan Driver Good Enough to Play Quake 3

Raspberry Pi 3 Vulkan VideoCore IV GPU

The Raspberry Pi Foundation is collaborating with Igalia to work on everything related to graphics support for VideoCore VI GPU found in Raspberry Pi 4’s Broadcom BCM2711 SoC. This lead to OpenGL ES 3.1 conformance at the beginning of the year, and good progress with Raspberry Pi 4 Vulkan support. There’s no plan to work on an official Vulkan driver for earlier Raspberry Pi  boards with VideoCore IV GPU, but since the Raspberry Pi Foundation released open-source VideoCore IV driver and documentation several years ago, it’s, in theory, possible for skilled developers to improve on it. That’s exactly what Martin Thomas, an NVIDIA engineer, has done in his spare time, and after two years of work, a Vulkan driver for Raspberry Pi VideoCore IV board – RPi-VK-Driver – has been released on Github. Pi-VK-Driver implements a subset of the Vulkan, and since it is not fully conformant to the standard […]

Orange Pi 4 Metal Enclosure Launched for $10

Orange Pi 4 Metal Enclosure

Orange Pi 4 and Orange Pi 4B, the latter further adding a Gyrfalcon 2801S AI accelerator chip, were launched in late 2019 for as little as $50 with 4GB RAM making those some of the most affordable Rockchip RK3399 SBC’s on the market. Since then, Shenzhen Xunlong Software launched some extra accessories for the board including a PCIe expansion board with a mini PCIe socket, and a SIM card slot, and very recently a Rockchip RM310 4G LTE modem to go along. The latest addition is a metal enclosure made of aluminum alloy and suitable for either version of the board. The enclosure is fairly compact with fins on top for cooling and openings for the 40-pin GPIO header and PCIe connector. Talking about PCIe, it would have been nice if they also make a case capable of taking their PCIe adapter board, but that would be for another time. […]

ESP32 Board Features mini PCIe & SIM Card Sockets for 4G LTE Connectivity

ESP32 SIM Card T-PCIe Board Pinout Diagram

LilyGO has launched yet another ESP32 WiFi & Bluetooth IoT board. As its name implies, TTGO-T-PCIe board includes a mini PCIe socket that coupled with a SIM card socket allowing users to insert a 4G LTE mPCIe card to add cellular connectivity. The company also offers optional SIM7000 2G or SIM7600 4G LTE modems that come with LTE and GPS antennas. You should probably be able to add other cellular mini PCiE, as well as other wireless mPCIe modems for LoRa, Satellite communication, etc… (Finally most probably not) TTGO-T-PCIe board specifications: Wireless module – ESP32-WROVER-B with ESP32 dual-core wireless SoC with 520KB SRAM, WiFi and Bluetooth with on-board antenna, as well as 4MB flash, and 8MB PSRAM Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps (ESP32) Bluetooth 5.1 LE (ESP32) Optional wireless cards via mPCIe socket (I2C and UART), SIM card slot for 2G and 4G LTE cellular networking […]

zGlue Launches the Open Chiplet Initiative in Collaboration with Google and Antmicro

Open Chiplet Initiative

We first covered zGlue’s ZiP (zGlue Integration Platform) in 2018 as the company introduced its multi-chip module similar to SiP (system-in-package) via a crowdfunding campaign. Just like SiP, the technology packages several components into a single package, but costs have been brought down to enable low-volume production of custom chips for a reasonable price. Since then the company announced new ZiP multi-chip modules such as nRF52832 based Omnichip and the FPGA, Arm or/and RISC-V based GEM ASIC by Antmicro. The company recently announced the Open Chiplet Initiative, a collection of open-source designs, tools and file formats, launched in collaboration with Google and  Antmicro. There are four main types of tools within the Open Chiplet Initiative: Open Chiplet Interfaces – Currently only ZEF (zGlue Chiplet Info Exchange Format) is provided. It defined the part numbers, pins, and mechanical dimensions of various parts. The ZEF specification can be found on Github. Design […]

Checking Out Raspberry Pi OS 64-Bit on Raspberry Pi 4 8GB RAM

Raspberry Pi OS 64-bit on Raspberry Pi 4 8GB

The Raspberry Pi 4 with 8GB RAM launched a couple of weeks ago together with the beta version of Raspberry Pi OS 64-bit. Note that you should currently use the 32-bit version of Raspberry Pi OS (previously known as Raspbian) as the 64-bit still has bugs and missing features, but I want to find out the current progress, so I installed raspios_arm64-2020-05-28/2020-05-27-raspios-buster-arm64.zip and had no problem to boot the board. Raspberry Pi OS 64-bit System Information After going through the setup wizard in the desktop environment to configure the language, time, networking, etc…, and make sure the OS is updated, I checkout some information:

I do have a Raspberry Pi 4 Model B Rev 1.4 with 8GB Memory (revision: d03114), the image comes with a 64-bit Linux kernel:

and we do get a 64-bit rootfs.

All good. Known issues Before starting the review, let’s make ourselves aware […]

Getting a 3-inch Smartphone in 2020? You can with Unihertz Jelly 2 (Crowdfunding)

3-inch smartphone 2020

Most smartphones have 5″ or larger displays these days as it’s just more convenient to read emails, browse the web, or play games, than the smaller displays we had ten years ago. But some people may still prefer smaller smartphones that are lighter and really fit into any pockets. Those are just pretty hard to find, luckily some companies such as Unihertz are filling the needs for this niche market. Two years ago, the company introduced the Unihertz Atom smartphone with a 2.4″ display, and earlier this year launched Atom XL 4″ smartphone, but the company is now preparing to launch a new crowdfunding campaign for Jelly 2 smartphone powered by a MediaTek Helio P60 processor and equipped with a 3-inch display. Unihertz Jelly 2 specifications: SoC – MediaTek Helio P60 octa-core with four Arm Cortex-A73 up 2.0 GHz and four Arm Cortex-A53 up to 2.0 GHz, Arm Mali-G72 MP3 […]
