Raspberry Pi CM4 based predictive maintenance gateway features Google Coral Edge AI accelerator

Techbase had already integrated the Raspberry Pi CM4 module into several industrial products including Modberry 500 CM4 DIN Rail industrial computer,  ModBerry AI GATEWAY 9500-CM4 with a Google Edge TPU, and ClusBerry 9500-CM4 that combines several Raspberry Pi CM4 modules into a DIN Rail mountable system. The company has now announced another Raspberry Pi Compute Module 4 gateway – iModGATE-AI – specially designed for failure monitoring and predictive maintenance of IoT installations, which also embeds a Google Coral Edge TPU AI module to accelerate computer vision. iModGATE-AI gateway specifications: SoM – Raspberry Pi Compute Module 4 with up to 32GB eMMC AI accelerator – Google Coral Edge TPU AI module Video Output – HDMI port Connectivity – Gigabit Ethernet USB – USB 2.0 port Sensors – 9-axis motion tracking module with 3-axis gyroscope with Programmable FSR, 3-axis accelerometer with Programmable FSR, 3-axis compass (magnetometer) Expansion 2x 16-pin block terminal Advanced […]

Top 5 most powerful Arm SBC’s & Devkits in 2021

While companies like Hardkernel, Raspberry Pi, Orange Pi, and FriendlyArm offers affordable, great little Arm Linux development boards that are suitable for many projects, in some cases, your requirements may lead you to spend a bit more for either extra CPU power, more memory, AI processing power, faster I/Os and so on. That’s why I did a list of the most powerful Arm single board computers in late 2017, but with over three years passed since then an update is warranted. The boards from the list must be easily purchasable from individuals (with the cash to spare) or small companies, so we’ll exclude hard-to-source hardware, as well as Arm server boards like Ampere eMAG motherboard, that do not really qualify as single board computers. Snapdragon 888 Mobile Hardware Development Kit While there are plenty of Cortex-A72/A73 development boards around, it’s much hardware to find one with more recent Cortex-X1 or […]

Piunora has the guts of a Raspberry Pi 4 with Arduino form factor, M.2 PCIe socket (Crowdfunding)

The Raspberry Pi 4 is a pretty cool board, but if you wished it was just a bit smaller, and you could use the PCIe interface exposed by the Broadcom BCM2711 processor more easily, Timon has designed Piunora carrier board for the Raspberry Pi Compute Module 4. The solution provides a board with the guts of Raspberry Pi 4 SBC but using the Arduino form factor including access to the six ADC pins, and an M.2 socket with the PCIe signal from the Broadcom SoC. Piunora carrier board specifications: SoM compatibility – Raspberry Pi CM4 module with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 1 to 8GB RAM, optional 4GB to 32GB eMMC flash, optional wireless module with 802.11b/g/n/ac WiFi 5 and Bluetooth 5.0 Storage – 1x MicroSD card socket (for the OS when using Raspberry Pi CM4Lite system-on-module) Video Output – 1x HDMI 2.0 port up to 4Kp60 […]

WM1302 LoRaWAN gateway mini PCIe module works over SPI or USB

Announced in 2019, Semtech SX1302 LoRa transceiver is designed for cheaper, and more efficient LoRaWAN gateways, and we’ve seen it in mini PCIe concentrator cards such as nFuse SX1302 and Rak Wireless RAK2287 using USB or SPI host interfaces. Seeed Studio adds another option with WM1302 LoRaWAN gateway mPCIe module using either SPI or USB interfaces and supporting 868 or 915 MHz frequency bands. WM1302 module specifications: MCU – STMicro STM3L412 Arm Cortex-M4 microcontroller @ 80 MHz with 40KB RAM, 64 or 128KB flash LoRa Connectivity Semtech SX1302 LoRa Transceiver with 2x SX1250 Tx/Rx front-ends Tx power – Up to 26dBm @ 3.3V Rx sensitivity – Down to -139dBm @ SF12, BW 125 kHz; -125dBm @ 125K/SF7 LoRaWAN 1.0.2 compatible. LoRa band coverage – EU868, US915, AS923, AS920, AU915, KR920, and IN865. u.FL antenna connector Misc – Power, Config, and Tx/Rx LEDs Host Interface – SPI or USB interface on […]

$30 Raspberry Pi CM4 IoT Router Carrier Board Mini offers Dual Gigabit Ethernet

We’ve recently written about Seeed Studio’s “Dual Gigabit Ethernet Carrier Board for Raspberry Pi Compute Module 4” that offers dual Gigabit Ethernet, and two USB 3.0 ports for software router applications, but it can also be used for IoT, Smart Home, and camera projects, as well as HTPC maker thanks to micro HDMI output and MIPI DSI/CSI connector. It is sold for an affordable $45, exceeding the Raspberry Pi CM4 module. But if all you want to do is get a dual Gigabit Ethernet WiFi router or IoT gateway, DFRobot has now introduced a more compact and cheaper carrier board for Raspberry Pi CM4: “Compute Module 4 IoT Router Carrier Board Mini“. CM4 IoT Router Board Mini specifications: Compatible Module – Raspberry Pi Compute Module 4 / 4 Lite with Broadcom BCM2711 quad-core Cortex-A72 processor, up to 8GB RAM, up to 32GB flash, optional 802.11b/g/n/ac WiFi 5 and Bluetooth 5.0 […]

Raspberry Pi CM4 Panel PCs offer IP67 protection, 7-inch display

We just have covered Raspberry Pi CM4 in CutiePi 8-inch tablet, but I don’t think I’ve seen the latest Raspberry Pi Compute Module inside a panel PC that typically offers additional interfaces such as Ethernet, RS232, or CAN bus for industrial applications. But today I’m here to write not about just one Raspberry Pi CM4 panel PC, but two from Chipsee and WIN Enterprises all with a 7-inch display, and features like Ethernet, opto-isolated GPIOs, RS485 terminal blocks, etc…, and the Win Enterprises’ model also adds dust and waterproofness with IP67 ingress protection rating. Chipsee CM4-70 Industrial Pi  7-inch Panel PC Chipsee panel PC is offered in two versions with CM4-70-EM model meant to be integrated into the customer’s own chassis, and CM4-70-PA integrating the board and display into a fully assembled panel. Specifications: SoM – Raspberry Pi Compute Module 4 (CM4) with Broadcom BCM2711 quad-core Cortex-A72 processor, 2GB RAM, […]

Raspberry Pi CM4 boards offer dual Ethernet, 4G LTE

Since the launch of Raspberry Pi CM4 and CM4Lite systems-on-module last October, we’ve seen carrier boards bring their own set of features including industrial communication interfaces, a stereoscopic camera, four SATA ports to build a NAS, a DIN-rail based industrial controller, and more. But so far, I have not seen a Raspberry Pi CM4 carrier board with dual Ethernet ports. Seeed Studio’s “Dual Gigabit Ethernet Carrier Board for Raspberry Pi Compute Module 4” was brought to our attention this morning, but there’s another one with 4G LTE connectivity, Fast+Gigabit Ethernet ports, and extra I/Os courtesy of MCUZone’s CM4-4G IO board. Let’s have a look at both of them. Dual Gigabit Ethernet Carrier Board for Raspberry Pi Compute Module 4 Specifications: Supported SoMs – Raspberry Pi CM4 and CM4Lite with up to 8GB RAM, 32GB eMMC flash, optional WiFi & Bluetooth Storage – MicroSD card slot to load OS on CM4Lite […]

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. […]
