SparkFun Raspberry Pi RP2040 & MicroMod boards take mikroBUS Click expansion boards

We’ve previously written articles about boards featuring the mikroBUS interface supporting thousands of Click expansion boards from Mikroelectronika, and now the company has collaborated with Sparkfun who launched MicroMod and Raspberry Pi RP2040-based boards with a mikroBUS socket, plus Qwicc connectors. Raspberry Pi RP2040 is the well-known dual-core Arm Cortex-M0+ microcontroller found in Raspberry Pi Pico and a range of third-party boards, while Sparkfun MicroMod‘s are M.2 MCU modules with chips from Microchip, Nordic Semi, Ambiq, Espressif Systems, and NXP. Sparkfun RP2040 mikroBUS development board specifications: MCU – Raspberry Pi RP2040 dual-core Cortex M0+ microcontroller up to 133 MHz with 264 KB SRAM Storage – 16MB QSPI flash, MicroSD card socket (on the bottom side) USB – USB Type-C port Expansion mikroBUS Socket 2x Qwiic connectors Thing Plus (or Feather) pin form factor with 18 GPIO pins including up to 4x 12-bit ADC, up to 8x 2-channel PWM, up to […]

Beagle-Pi Emulator is a Raspberry Pi HAT adapter for BeagleBone Black (Crowdfunding)

Beagle-Pi Emulator BeagleBone Black Industrial

We recently reported the Raspberry Pi boards were getting really expensive due to a lack of supply, and the problem has gone on for while without a clear idea when the issue will be resolved. This does not help Raspberry Pi HAT manufacturers, and for instance, Sequent Microsystems has made Raspberry Pi HATs over the years most models with multiple relays, but also others for temperature sensors, and others automation applications. One solution would be to use compatible boards like ODROID-C4 or Rock64, but Sequent Microsystems found out the BeagleBone Black Industrial was well-stocked by various distributors, and instead, they designed the “Beagle-Pi Emulator” adapter to use Raspberry Pi HAT on the Texas Instruments Sitara AM3358 board. An adapter is needed because the BeagleBone Black boards are equipped with two 46-pin headers instead of the 40-pin header on Raspberry Pi SBC’s. The expansion board routes I2C, SPI, four serial […]

Pigeon RB700 is a DIN Rail automation controller with RS-485, RS-232, Ethernet, CAN FD, 1-WIRE, RS-232, and more

We’re covered DIN-Rail industrial computers powered by Raspberry Pi CM4 module, but Kristech’s Pigeon RB700 automation controller may be the one with the most features so far thanks to two RS-485 ports, two Ethernet ports, CAN FD, 1-WIRE, RS-232, 12 digital inputs (8 optoisolated, 4 dry contacts), and 8 digital outputs. That’s for the common features present in all variants including RB700 Essense. The RB700 Standard model adds UPS, HDMI, analog I/Os, and TPM, while the RB700 Advance is further equipped with two M.2 sockets (for SSD and/or cellular modem) and two additional RS-232 ports. Pigeon RB700 specifications: Supported SoM- Raspberry Pi CM4 with up to 8GB RAM, up to 32GB flash, optional WiFi 5 and Bluetooth 5.0 module Video Output (Standard and Advance) – HDMI port Networking – 2x Ethernet ports USB – 2x or 3x USB 2.0 ports Wired communication interfaces 3x RS-232, 2x RS-485, CAN FD, 1-Wire […]

Raspberry Pi 4 4GB/8GB price is going through the roof (over 100 Euros in Europe)

While Raspberry Pi Foundation provides a fixed price for their single board computers before taxes and shipping, the street price may be different, and I’ve seen several reports on Twitter of the Raspberry Pi 4 with 4GB RAM now selling for over $100 due to the lack of supplies. The problem seems especially pronounced in Europe with some users reporting a price close to 120 Euros, instead of the usual 50 to 60 price range. Geizhals price comparison website did even show the Raspberry Pi 4 with 8GB RAM selling for up to 149.99 Euros (About $170) just last week, but prices have now gone down to just around 100 Euros, clearly a steal! The price for Raspberry Pi 4 with 4GB RAM has also gone down, but it is still at 89.90 Euros according to the Heise’s price comparison website. This is probably a regional pricing issue, but the […]

OpenScan DIY 3D scanner works with Raspberry Pi, DSLR, or smartphone cameras

OpenScan is an open-source DIY 3D scanner that relies on Photogrammetry and works with Raspberry Pi camera modules, compatible ArduCam modules, as well as DSLR cameras, or the camera from your smartphone. The open-source project was brought to my attention after I wrote about the Creality CR-Scan Lizard 3D scanner. The OpenScan kits include 3D printed parts such as gears, two stepper motors, a Raspberry Pi shield, and a Ringlight module to take photos of a particular object from different angles in an efficient manner. The OpenScan Classic kit above allows for 18x18x18cm scans and comes with the following components: 1x Nema 17 Stepper Motor (13Ncm) 1x Nema 17 Stepper Motor (40Ncm) 2x A4988 Stepper driver 1x Power Supply 12V/2A (5.5-2.5mm plug) 1x Optional Bluetooth remote shutter control for smartphones If you’re going to use the Raspberry Pi as shown on the right side of the image, you’ll also need […]

Challenger RP2040 LoRa board combines Raspberry Pi RP2040 MCU with RFM95W LoRa module

Invector Labs is now offering a variant of the WiFi-based Challenger RP2040 board with a LoRa radio. The Challenger RP2040 LoRa board features the Hope RF RFM95W LoRa radio transceiver module instead of the ESP8285 WiFi chip found in the original board. Raspberry Pi RP2040 has already been used in combination with a LoRa module, notably in Rakwireless RAK11300 WisDuo LPWAN module and the “LoRa Expansion for Pico“, a baseboard for Raspberry Pi Pico equipped with a LoRa module, but it’s the first time I see the combination in a development board form factor, which as a potential bonus following Adafruit Feather form factor. Challenger RP2040 LoRa board preliminary specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU @ 133MHz with 264KB SRAM Storage – 8MB flash Wireless module – Hope RF RFM95W connected via SPI channel and some GPIOs 168 dB maximum link budget. +20 dBm – 100 mW […]

Raspberry Pi RP2040 gains an extra USB port through PIO’s (programmable I/Os)

The Raspberry Pi RP2040 specifications only list one USB 1.1 Host/Device hardware interface, but developer’s Sekigon Gonnoc decided to leverage the microcontroller’s programmable I/Os (PIO) to add an extra USB port that also works in host or device mode. While the C library is still supposed to be a work in progress Sekigon implemented full-speed (12 Mbps) and slow-speed (1.5Mbps) host, full-speed device, USB hub, and multi-port support. There’s even a demo with three “Pico Pico USB” keyboards acting as USB hubs and HID plus a wireless mouse to show the results. The implementation uses one PIO for the USB transmitter using 22 instructions and one state machine and another PIO for the USB receiver using 31 instructions and two state machines, as well as one 1ms loop timer for the host, and one PIO interrupt for the receiver. You’ll find the code to implement the extra USB port on […]
