It’s raining i.MX 8M Plus systems-on-module at Embedded World 2021

NXP introduced i.MX 8M Plus AI SoC with a built-in 2.3 TOPS neural processing unit (NPU) last year, and we’ve already covered several early announcements about i.MX 8M Plus systems-on-module (SoM) with Variscite VAR-SOM-MX8M-PLUS and DART-MX8M-PLUS, TechNexion EDM-G-IMX8M-PLUS and AXON-E-IMX8M-PLUS respectively using SO-DIMM edge connectors and board-to-board connectors, as well as SolidRun i.MX 8M Plus SoM that was announced together with the HummindBoard Mate carrier board with dual Gigabit Ethernet. But as Embedded World 2021 Digital is taking place virtually until Friday, other companies have now made their own announcements of i.MX 8M Plus SoMs as the processor enters mass production this month, and since as far as I know, it’s pin-to-pin and software compatible with earlier i.MX 8M Nano/Mini SoCs, the update must have been easy. That means we’ve got a longish list of modules, and I have probably missed some. Supported operating systems are basically the same across […]

Arduino IDE 2.0 beta released with live debugger, revamped user interface

Arduino programming language and the Arduino IDE are the most popular software development tools for the makers market, but it lacks some of the features found in professional tools like autocompletion and the ability to add breakpoints via a debugger, and that’s why the company announced its work on the Arduino Pro IDE in 2019. Work is now nearing completion with the release of the beta version of the Arduino IDE 2.0 based on the Eclipse Theia framework. The user interface has been revamped with easy access to the newly added debugger, as well as the boards manager and libraries manager on the left side of the interface, the possibility to type the name of the board, and autocompletion of variables and functions from your code and installed libraries. Pressing F12 while on a function name will bring you directly to the corresponding code in another tab, or alternatively, you […]

Raspberry Pi RP2040 boards are coming with… HDMI?

We’ve already seen Raspberry Pi RP2040 MCU can support VGA output using the microcontroller’s programmable I/O blocks. But yesterday, I saw two upcoming RP2040 boards with an HDMI connector. How is that supposed to work? The first one is Olimex RP2040-PICO-PC that’s indeed like a pico PC board with an HDMI connector for video, a micro SD card for storage, a standard 3.5mm audio jack for speaker or headphone, and a USB host for a keyboard. RP2040-PICO-PC teaser small PC with RP2040-PICO module.

The second board, dcelectr DC2040, follows the […]

tCam-Mini IR thermal camera board ships with ESP32 module

While there are plenty of ESP32 camera boards, it’s much harder to find off-the-shelf solutions with ESP32 wireless SoC and an IR thermal camera. That’s likely why Dan Julio decided to design tCam-Mini board combining an ESP32 module with a Flir Lepton 3.5 sensor with 160×120 resolution to capture radiometric data for thermographic analysis. tCam-Mini board hardware specifications: Wireless module – Espressif ESP32-WROVER-E module with dual-core ESP32-D0WD0V3 WiSoC, 8 MB PSRAM, 8 MB Flash, and PCB antenna; Camera – Flir Lepton 3.5: 160×120 pixel radiometric LWIR camera with shutter operating in either Radiometric/TLinear (each pixel contains temperature data) or AGC modes (no temperature data in each pixel but better images). Expansion – 4-pin I2C header Debugging – Micro USB port with CP2102N-A02 USB to UART bridge for ESP32 boot loader control Misc – Dual color (Red/Green) status LED, Factory/Wifi Reset button Power supply – 5V input via micro USB port […]

NVIDIA introduces lower cost Jetson TX2 NX SO-DIMM module

NVIDIA Jetson AI modules and developer kits range from the entry-level Jetson Nano module (5W, ~0.5 TOPS) to the high-end Jetson Xavier AGX module (30W, 32 TOPS). The higher-end modules usually come with a 400-pin board-to-board, while cheaper/cost-down modules like Jetson Nano and Jetson Xavier NX feature a 260-pin SO-DIMM connector and small form factor. But so far all Jetson TX2 modules came with a 400-pin connector, but this has changed with the introduction of the Jetson TX2 NX SO-DIMM system-on-module that is offered as a cost-down version of Jetson TX2 4GB module. NVIDIA Jetson TX2 NX specifications with highlights in bold or strikethrough showing the difference against Jetson TX2 4GB: Processor – Dual-Core NVIDIA Denver 2 64-Bit CPU and Quad-Core Arm Cortex-A57 MPCore processor @ up to 2.0 GHz GPU – 256-core NVIDIA Pascal GPU @ up to 1.3 GHz AI Performance – 1.33 TFLOPS Video Encode H.265 – […]

3.5-inch Atom x6000E embedded SBC features 3x GbE, 2x SATA, 6x USB, and more

Several Elkhart Lake SBC’s integrate two Ethernet ports including Avalue ECM-EHL 3.5-inch SBC or Congatec Conga-PA7 Pico-ITX board with the former equipped with 2.5GbE and GbE ports, and the latter two GbE ports. But if your industrial project requires more Ethernet ports, iBase IB836 3.5-inch Atom x6000E embedded SBC offers three Gigabit Ethernet RJ45 ports, as well as two SATA ports, six USB interfaces, plus various display options, as well as M.2 and mPCIe expansion sockets. iBase IB836 specifications: Elkhart Lake SoC (one of the other) Intel Atom x6425E quad-core processor @ 1.8GHz/3.0GHz, with 1.5MB cache, Intel UHD graphics; 12W TDP Intel Atom x6413E quad-core processor @ 1.5GHz/3.0GHz, with 1.5MB cache, Intel UHD graphics; 9W TDP Intel Atom x6211E dual-core processor @ 1.2GHz/3.0GHz, with 1.5MB cache, Intel UHD graphics; 6W TDP System Memory – Up to 32GB via DDR4-3200 SO-DIMM, with IBECC support Storage – 2x SATA ports, 1x mSATA […]

A neat way to add a reset button to Raspberry Pi Pico

The Raspberry Pi Pico is a nice little board, but if you program in C language, you’d need to disconnect the micro USB cable each time you’d like to flash the UF2 firmware. That’s not convenient and could damage your board over time. The Raspberry Pi Foundation even decided to write a blog post explaining how to add a reset button to your Raspberry Pi Pico using a breadboard circuit. Here’s what it looks like. That works but you may want to use that breadboard for another circuit, so the reset button takes space. Another solution is to program with a Raspberry Pi board and use SWD mode to upload code using the debug port, instead of using mass storage (BOOTSEL) mode. I’ve also found out that most baseboards for the Pico board will include a reset button. But this morning, I’ve come across another solution that looks pretty neat. […]
