[Update January 28, 2021: The LoRa version of Portenta Vision Shield is now available] Announced last January at CES 2020, Arduino Portenta H7 is the first board part industrial-grade “Arduino Pro” Portenta family. The Arduino MKR-sized MCU board has plenty of processing power thanks to STMicro STM32H7 dual-core Arm Cortex-M7/M4 microcontroller. It was launched with a baseboard providing access to all I/Os and ports like Ethernet, USB, CAN bus, mPCIe socket (USB), etc… But as AI moves to the very edge, it makes perfect sense for Arduino to launch Portenta Vision Shield with a low-power camera, two microphones, and a choice of wired (Ethernet) or wireless (LoRA) connectivity for machine learning applications. Portenta Vision Shield key features and specifications: Storage – MicroSD card socket Camera – Himax HM-01B0 camera module with 324 x 324 active pixel resolution with support for QVGA Image sensor – High sensitivity 3.6μ BrightSense pixel technology […]
Agromon smart agriculture wireless transmitter connects ModBus RS485 sensors to WiFi, LoRaWAN, Sigfox, or NB-IoT
The Internet of Things has many applications including smart agriculture . A few months ago, I talked to a local shrimp farm owner who used Arduino and ESP8266 boards to monitor water and activate pumps only when needed to get shrimps healthy and save on his electricity bill. He built his own solutions, but there are also companies offering easy-to-use smart farming solutions such as Malaysia-based Wondernica’s Agromon “interface wireless transmitter” designed specifically for smart agriculture applications. Agromon has two variants with support for 2 sensors (WR-AGRO-2S) or 3 sensors (WR-AGRO-3S) that share the following specifications: Connectivity – WiFi, Sigfox (RCZ 2/4), LoRaWAN, NB-IoT Sensor Interface – Modbus RS485 (analog input / 4-20mA / 12V-14V output) Power Supply – 12V DC (tolerance up to 14V); supports batteries, solar power, or power adapter Power Consumption – Sleep Mode: 3 mW Dimensions – 130 x 90 x 40mm Ingress Protection – IP67 […]
OnLogic Elkhart Lake fanless mini PC’s are made for IIoT applications
Intel Atom x6000E Series, Celeron and Pentium Elkhart Lake IoT Edge processors were introduced in September 2020, and we covered several Elkhart Lake modules and SBC’s. We’ve seen fewer full systems such as the Atom x6425RE based Vecow SPC-6000 Elkhart Lake mini PC for embedded & IoT applications. But OnLogic is more offering four more choices with Helix 300 and Karbon K400 Series of rugged fanless mini PCs, all equipped with Atom, Celeron, or Pentium Elkhart Lake processors, and designed for industrial IoT (IIoT) or Industry 4.0 applications Helix 300 Series Specifications The Helix 300 family is comprised of two models with Helix 310 and Helix 330 share most of the same specifications: SoC – Intel Celeron N6211 dual-core processor or Pentium J6425 quad-core processor System Memory – Up to 32 GB DDR4 RAM Storage – M.2 Storage Video Output – 3x DisplayPort for triple independent display setups Audio – […]
Mini replica of DEC PDP-11 computer runs 2.11 BSD UNIX on ESP32 SoC
The relatively popular Digital Equipment Corporation (DEC) PDP-11 16-bit minicomputers started selling in the 70s, and were still available in the earlier 90s. While being stuck in Europe due to COVID-19 restrictions, Jeroen Domburg (aka Sprite_tm) decided to design a tiny replica of a DEC VT102 PDP-11 terminal based on ESP32 wireless SoC and running 2.11 BSD UNIX through SimH PDP11 emulator. Jeroen had to do significant work to make SimH works on ESP32 however, with notably the need to optimize the memory footprint: Obviously, ‘just port SIMH to an ESP32’ is a bit of a understatement for the effort that was needed. Even while SIMH is a pretty nice program when it comes to not using any unique APIs, it still is a system developed for a full-blown workstation and assumes RAM is cheap and plentiful. In order to get it running on an ESP32 and still have some […]
A closer look at Raspberry Pi RP2040 Programmable IOs (PIO)
The popularity of Raspberry Pico board powered by RP2040 microcontroller has made every reader wanting to know more about the board and chip. So today we will be talking about RP2040’s Programmable IOs, a feature that makes it different from most other microcontroller boards. The two PIO blocks or let’s call it the hardware interfaces in the RP2040 have four state machines each. These two PIO blocks can simultaneously execute programs to manipulate GPIOs and transfer raw data. Now, what do these state machines do? Well, the PIO state machines execute the programs fetched from various sources. Sometimes the programs are taken from the PIO library (UART, SPI, or I2C) or user software. Why Programmable I/O? All the boards usually come with hardware support for digital communications protocols such as I2C, SPI, and UART. However, if you plan to use more of these interfaces than what is available on the […]
Rockchip RV1109 SBC’s provide access control solutions with optional 4G LTE connectivity
We’ve been writing about Rockchip RV1109 and RV1126 AI camera SoC’s in recent days, as well as evaluation boards and modules, plus some complete solutions such as Firefly dual-lens AI camera modules. Shenzhen-based JWIPC, a company specifically in embedded PCs and motherboards, has designed three SBC’s powered by Rockchip RV1109 processor especially designed for access control, leverage the face detection capabilities of the Rockchip processor. The three access control boards are: R19S – Standard 100x72mm Pico-ITX board with industrial grade materials, support for wide temperature, hardware watchdog, and “rich peripheral interface”. R19F- Same as R19S, but with a mini PCIe socket for a 4G LTE module, plus a SIM card slot R19N – Similar to R19S with a narrower 100x60mm design JWIPC R19 boards share most of the same hardware key features and specifications: SoC – Rockchip RV1109 dual-core Arm Cortex-A7 @ 1.5 GHz, plus RISC-V MCU @ 400 MHz, […]
4K AV1 Android TV dongles surface with Amlogic S905Y4 Cortex-A35 processor
Amlogic S905X4 is a quad-core Cortex-A55 SoC for 4K TV boxes and set-top boxes with H.265, H.264, VP9, and AV1 hardware video decoding. The silicon vendor usually provides a lower cost version of the processor for dongles without Ethernet, but keeping most of the same features, as we’ve seen in the past with S905X2 and S905Y2 processors for instance. S905X4 has now its own cost-down version with S905Y4 for Android TV (certified) dongles relying on WiFi for connectivity, but instead of keeping Cortex-A55 cores, the processor features four low-power Cortex-A35 cores. We do not have the full details about S905Y4 processor just yet, but it has start to show in dongles from SEI Robotics and SDMC that appears idendical. SDMC DV6071Z / SEI Robotics SEI450 TV dongle specifications: SoC – Amlogic S905Y4 quad-core 64-bit Arm Cortex-A35 processor with Mali-G31 MP2 GPU System Memory – 2GB DDR (4GB optional) Storage – […]
