Raspberry Pi 4 Rev 1.2 Fixes USB-C Power Issues, Improves SD Card Resilience

Raspberry Pi 4 v1.2

The first Raspberry Pi 4 boards suffered from a poor USB-C power supply compatibility due to issues for the power circuitry. That means if you bought the official USB-C power supply you had no issues, but if you wanted to re-use a spare USB-C power supply or incompatible cable, you may be out of luck. The Register is now reporting that the Raspberry Pi Foundation has discreetly released a new revision (v1.2) of the board that fixes several issues including USB-C PD compatibility, and as Eben Upton explains the new revision also: moved the WLCSP SD card voltage switch to the top side … silk screen tweaks to reduce solder bridging in manufacture”. The new boards have been around for a couple of months as some users report the USB-C power issues have been fixed on new boards. Spotting Differences in the new Raspberry Pi 4 Rev 1.2 Board? The bad news is if you buy the board online, nobody …

PicoCore MX8MN is a Tiny NXP i.MX 8M Nano Computer-on-Module

The PicoCore MX8MN Nano carries the NXP i.MX 8M Nano F&S Elektronik Systeme has announced the development of the smallest i.MX 8M based CoM yet: the PicoCore MX8MN Nano. Previously we had reported on the Congatec Conga-SMX8 Nano which was a fairly small CoM compliant with SMARC 2.0 standard. The PicoCore MX8MN is based on the NXP i.MX 8M Nano CPU with 1 to 4 Arm Cortex-A53 cores and a Cortex-M7 real-time core. The Nano is set to carry up to 8GB RAM and 32 GB eMMC, with optional WiFI/BT and support for -40º C to 85º C temperature ranges. Similar to Predecessor The PicoCore MX8MN Nano is very similar in structure to the PicoCore MX8MM Mini CoM, but with a different i.MX 8M Mini processor featuring the same Arm Cortex-A53 cores, but the Cortex M4 real-time core is changed to a more powerful Cortex-M7 core in the MX8MN Nano. The MX8MN Nano has no photo on the product page …

Toradex Launches New Verdin Arm SoM Family Starting with iMX8M Mini/Nano Modules

Verdin iMX8M Mini / Nano

So far, Toradex had two Arm-based system-on-module families with the smaller, lower-power Colibri and more powerful Apalis modules. The Colibri form factor was first defined in 2005, and the company is still maintaining it, but since then new interfaces have emerged, so Toradex has now designed a new low-power module family called Verdin. Toradex Verdin modules offer more I/Os with a 260-pin edge connector, include a battery-ready design with a wide input voltage range (3.3 to 5V), low power 1.8V IOs, the ability to easily extend power management to carrier board peripherals, and off-the-shelf thermal solutions. The modules are also tested for EMC, shock and vibration tolerance, and “Toradex Direct Breakout” is said to simplify signal routing on carrier boards as high speed, impedance critical signals are routed from the source IC to the edge connector on the Verdin module in such a ways to limit complexity on the carrier board. Verdin iMX8M Mini/Nano Modules The first Verdin SoM’s are …

ADLINK Industrial-Pi (I-Pi) SMARC Development Kit Features Rockchip PX30 SoC

ADLink Industrial Pi-SMARC Devkit

ADLINK Technology has just announced the Industrial-Pi (I-Pi) SMARC Development Kit to help engineers quickly design prototypes for industrial applications using peripherals and sensors. The I-Pi SMARC development kit is comprised of a baseboard, LEC-PX30 SMARC-compliant Rockchip PX30 system-on-module, an acrylic case, a 12V/2A power supply, USB cable, and a 32GB MicroSD card. The company promotes the kit as “an industrial-ready substitute for Arduino and Raspberry Pi (RPi) platforms that are commonly used for prototyping but cannot typically be ‘dropped’ into an industrial solution as-is“.

Barracuda App Server for ESP32 Let You Easily Develop Lua Apps via Your Web Browser

Barracuda App Server ESP32

We covered Real Time Logic’s open-source lightweight Minnow Server for microcontrollers last year, and now the company has released another project: Barracuda App Server for ESP32. This project is more complex and requires an ESP32 board with PSRAM to run such as boards based on ESP32-WROVER module with 4 to 8MB PSRAM. The Barracuda App server (BAS) comes with a Lua VM, and in complement with the LSP App Manager that facilitates active development on the ESP32 by providing a web interface. The Barracuda App Server runs on top of FreeRTOS real-time operating system part of Espressif free ESP-IDF development environment. The company provides instructions to build BAS from source, as well as the LSP (Lua Server Pages ) App Manager that links to the binary-only BAS library. The Linux version of the ESP-IDF is recommended, so in Windows, you should install the “Windows Subsystem for Linux” first. The source code for LSP App manager can be found in Github, …

The Things Industries Launches Global Join Server for Secure LoRaWAN

Global Join Server

Co-Founder and CEO of The Things Industries Wienke Giezeman announced the launch of Global Join Server (GJS) which is a secure component of the LoRaWan server. As an ecosystem, Global Join Server allows activating devices of any LoRa network from anywhere on the World. According to Giezeman, it works with the Things Network, the Community Network, cloud hosting solutions, etc. It works no matter if it is a part of a network server outside the Things Industries, as long it uses LoRa standard interfaces. The Global Join Server’s role is to store root keys, generate session keys and send them securely to the Network Server and Application Server. There is no more need to send keys by email or to print them on the boxes, they are already in a secure place. The Things Industries offers to device makers, module makers and distributors, access to a network-agnostic Join Server of LoRaWAN. With GJS there is no need for manufacturers to …
