Since Arduino plans to launch its own Raspberry Pi RP2040 based board with Arduino Nano RP2040 Connect, one would have expected software support for the Arduino IDE would have come from the company itself. But apparently, the developer community, or more exactly Earle F. Philhower, III did not feel like waiting. He had previously written ESP8266Audio library for audio file and I2S sound playing routines for ESP8266 & ESP32, and has recently released Raspberry Pi Pico Arduino Core on arduino-pico Github repository. The implementation appears to be already fairly comprehensive with support for digitalWrite/Read, shiftIn/Out, SPI master, analogWrite/PWM, Wire/I2C Master and Slave, analogRead and Pico chip temperature, filesystems like LittleFS and SD/SDFS, I2S audio output, and more. The Raspberry Pi RP2040 programmable IOs are also used to control servos, generate tones, and I2S output. You’ll need the Arduino IDE 1.8.x or the beta version of Arduino IDE 2.0, and add […]
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 […]
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.

$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 […]
It’s now easier to customize Raspberry Pi OS images
When I need to flash a Raspberry Pi OS image, I usually download the image from the Raspberry Pi website before flashing it to a MicroSD card with either balenaEtch or USBimager. The Raspberry Pi Foundation released the Raspberry Pi Imager last year, but I never used it, except to try it out, because at the time, it would just flash the image to the MicroSD card like other tools, and since I’m working with SBCs from different vendors it did really not bring any benefits to me. But with the v1.6 release, the Raspberry Pi tool has become more useful to advanced users, notably those who like to set up the image in a headless Pi. Before we had to flash the image, mount the MicroSD card, and go edit /boot/config.txt to enable SSH and other settings. Now, it’s possible to do the same from Raspberry Pi Image v1.6 […]
Pockit modular Linux computer takes hot plugging magnetic blocks
There have been attempts to create modular computers and smartphones to reduce electronics waste and improve user-serviceability over the years with initiatives and products like Google Project Ara, PinePhone and Fairphone3 smartphones, DevTerm mini computer, Olimex TERES-I laptop, and many more. Here’s another modular computer project that looks really cool. Pickit modular computer is comprised of an STM32+ESP32 based mainboard with a socket for an optional Raspberry Pi Compute Module 3. The board includes magnets and electrical contacts to snap and hot-plug modules/blocks while the computer is running. The video demo embedded further below, is really impressive, but let’s check out Pockit preliminary specifications first: MCU – STMicro STM32 microcontroller Wireless MCU – ESP32 dual-core processor with WiFi and Bluetooth LE CPU module – Socket for Raspberry Pi Compute Module 3 Expansion 24+ feature BLOCKS ready to use with instant connection using magnetic-snaps including Ethernet, Display (HDMI), audio, sensor modules […]
CutiePi tablet gets a Raspberry Pi CM4 upgrade
CutiePi tablet was launched on Kickstarter last year with a Raspberry Pi Compute Module 3+ Lite, an open-source hardware carrier board, and an 8-inch multi-touch display with 1280×800 resolution. Shipping to backers is about to start, but the company has already started working on a new version of the CutiePi Tablet with the Raspberry Pi CM4 module released last October. This will enable greater performance and more memory with the tablet shipping with a 2GB RAM CM4 module by default. CutiePi CM4 tablet preliminary specifications: SoM – Raspberry Pi Compute Module 4 Lite with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, 2GB RAM Storage – MicroSD card slot Display – 8-inch 5-point multi-touch IPS LCD with 1280×800 resolution Video Output – Micro HDMI Audio – 2W 8Ohm speaker, audio amplifier, built-in microphone Camera – 5MP front-facing camera (OV5647) Connectivity – Dual-band 802.11 b/g/n/ac WiFi 5 and Bluetooth 5.0 USB […]
