Setting up a private LoRaWAN network with WisGate Connect gateway

RAKwireless Wisgate Connect Gateway Review with Link.ONE devit

In this guide, we’ll explain how to set up a private LoRaWAN network using the Raspberry Pi CM4-based RAKwireless’ WisGate Connect gateway and Docker or Portainer to install NodeRED, InfluxDB, Grafana, and other packages required to configure our gateway. The WisGate Connect is quite a versatile gateway with Gigabit and 2.5Gbps Ethernet plus several optional wireless connectivity options such as LoRaWAN, 4G LTE, 5G, WiFi 6, Zigbee, WiFi HaLoW, and more that can be added through Mini PCIe or M.2 sockets, expansion through WisBlock IO connectors and a 40-pin Raspberry Pi HAT connector. We’ll start by looking at the gateway features in detail, but if you already know all that, you can jump to the private LoRaWAN network configuration section. WisGate Connect unboxing, specifications, and teardown RAKwireless sent us a model with a Raspberry Pi CM4 equipped with 4 GB of RAM and 32 GB of eMMC memory, GPS and […]

Mini review of GGtag e-paper display programmable through sound or USB serial

GGtag is a 3.52-inch e-paper display based on the Raspberry Pi RP2040 microcontroller and programmable through sound or USB serial from your web browser, plus it also supports emulation of 125 kHz RFID tags (ASK and FSK). When Radoslav Gerganov contacted me about the upcoming Crowd Supply campaign for the GGtag e-paper badge, I happened to have just discussed using an e-paper display to sell some samples on Facebook Groups where requirements include using the seller’s name and date in the photos. So I asked for a sample if any were available, and I just received it today… GGTag specifications: MCUs Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM Microchip ATtiny85 8-bit AVR microcontroller (used for RFID) Storage – 2 MB flash Display – 3.52-inc e-paper display with USB – 1x USB Type-C port for power and serial programming Sensor – PDM digital microphone for data-over-sound […]

Chart confirms higher level of Raspberry Pi restocks

Earlier this month, we noted that Raspberry Pi supplies were improving mostly from tweets from Eben Upton who provided data about shipped boards since the beginning of the year. But there are also third-party data that confirm this since RPILocator provides statistics for restocks of Raspberry Pi hardware from approved resellers. The chart below shows weekly data of restocks since January 2022 until today, and we can clearly see a jump in restocks in recent weeks, especially for the Raspberry Pi 4, so there’s no need to steal old boards from discarded scooters anymore 😉 The ramp-up really started on week 25 (June 19-25) and peaked on week 28 (July 10-16) possibly to fill back orders, and restocks have been going down in recent weeks but still at a higher level than previously. While the improvement is mostly visible for the Pi 4, the Raspberry Pi 3 and Raspberry Pi […]

myCobot Pro 600 Raspberry Pi 4-based robot arm supports 600mm working range, up to 2kg payload

Elephant Robotics has launched its most advanced 6 DoF robot arm so far with the myCobot Pro 600 equipped with a Raspberry Pi 4 SBC, offering a maximum 600mm working range and support for up to 2kg payloads. We’ve covered Elephant Robotics’ myCobot robotic arms based on Raspberry Pi 4, ESP32, Jetson Nano, or Arduino previously, even reviewed the myCobot 280 Pi using both Python and visual programming, and the new Raspberry Pi 4-based myCobot Pro 600 provides about the same features but its much larger design enables it to be used on larger areas and handles heavier objects. myCobot Pro 600 specifications: SBC – Raspberry Pi 4 single board computer MCU – 240 MHz ESP32 dual-core microcontroller (600 DMIPS) with 520KB SRAM, Wi-Fi & dual-mode Bluetooth Video Output – 2x micro HDMI 2.0 ports Audio – 3.5mm audio jack, digital audio via HDMI Networking – Gigabit Ethernet, dual-band WiFi […]

Raspberry Pi Pico to Arduino Uno adapter relies on “FlexyPins” for castellated holes

Raspberry Pi Pico Arduino UNO adapter FlexyPins

Solder Party’s “Raspberry Pi Pico to Uno FlexyPin Adapter” transforms the Raspberry Pi Pico into an Arduino UNO without soldering the board directly or using headers, but instead relying on FlexyPins flexible pins to attach the Pico board to the adapter using its castellated holes. The end result is basically the same as for the WisdPi ArduPico board, except the Raspberry Pi Pico is soldered to the main PCB on the latter, but it can be easily removed from the Solder Party’s Uno adapter board to be replaced with another compatible model, e.g. Raspberry Pi Pico vs Pico W. The FlexyPins can be used with any board or module with castellated holes, but it’s obviously especially useful for castellated modules without through holes, for example, to easily program a bunch of ESP32 modules. You’ll first need to get a few FlexyPins as shown below. Then solder them to a compatible […]
