The RP2040 Connectivity Board — An IoT solution combining LTE, Wi-Fi, and BLE into a single platform

ilabs rp2040 connectivity board

iLABs (Invector Labs), a European embedded equipment manufacturer, has released a new device, the RP2040 Connectivity Board, an IoT development board that is based on Raspberry Pi’s signature microcontroller IC, the RP2040. The RP2040 Connectivity Board features key IoT connectivity options such as LTE, Wi-Fi, and BLE (Bluetooth Low Energy). It is compatible with both Arduino and PlatformIO and is designed for professional and hobbyist users with wide-ranging connectivity needs. The SARA-R412M series module from u-blox handles cellular communication (LTE) and can be configured to enable multi-regional coverage in both GSM and LTE-M/NB-IoT radio transmissions. It features a unique and immutable root of trust and supports IoT security as a service. The RP2040 Connectivity Board also includes an Espressif ESP32-C3FN4 chip for Wi-Fi/BLE communication based on a RISC-V microcontroller core and implementing a Wi-Fi subsystem that complies with the IEEE 802.11b/g/n standard and supports various operating modes. The Bluetooth Low […]

The Lark Weather Station works with Arduino, ESP32, micro:bit, Raspberry Pi, and other boards

Lark Weather Station Arduino ESP32 Raspberry Pi

The Lark Weather Station measures wind speed, wind direction, temperature, humidity, and air pressure through a range of sensors and connects to popular development boards such as Arduino UNO, ESP32, BBC micro:bit, Raspberry Pi, or DFRobot Unihiker through I2C or UART. We’ve seen several projects for Internet-connection weather stations that retrieve weather data from the web and display the results locally, but the Lark Weather Station allows the users to get atmospheric data right in his/her current location thanks to its built-in anemometer, wind vane, and built-in sensors, as well as expansion interfaces for additional sensors. Lark Weather Station specifications: Storage – 16MB flash good to store about 160 days of data (when data is recorded once per minute) Sensors Compass Anemometer Wind Speed: 0.5~12m/s Cover to protect the anemometer during storage/transport Wind vane and wind direction shaft to report the wind direction (eight directions) Temperature Range –20~60℃ ±0.2℃ Humidity […]

RAKwireless open sources RUI3 multi-target IoT development platform

Rakwireless RUI3 open source IoT development platform

RAKwireless has made its RUI3 IoT software development platform open-source so that customers or users can implement “nice-to-have” features on top of the features already implemented by the company which could make it even more versatile in a wider range of IoT scenarios. Introduced in 2022, the RAK Unified Interface v3, or RUI3 for shorts, is a modular IoT platform based on the Arduino SDK with additional functions for IoT connectivity and low power that supports a variety of devices and applications. So developers can learn the language, code once, and use the same software on multiple WisBlock core platforms including Nordic Semi nRF52, STM32, ESP32, and Raspberry Pi RP2040 instead of having to juggle between different the Arduino BSP, the ESP-IDF framework, Nordic nRF Connect SDK, or Raspberry Pi C SDK. Users could already use the RUI3 firmware with the RAK3172 (STM32), RAK4630/RAK4631 (nRF52), or RAK11720 (Apollo3) WisBlock Core […]

Golioth expands its free tier for developers with unlimited IoT devices, OTA updates, 1GB bandwidth

Golioth IoT platform unlimited devices

When we first wrote about the Golioth IoT development platform with ESP32 and nRF9160 devices support in 2022, we noted they offered a free Dev Tier account for up to 50 devices, 10 MB of LightDB data with a 7-day retention policy, and other limitations. The company has now decided to remove many of the limitations from the free developer tier without any limit to the number of IoT devices and also added other benefits: Unlimited Device Connections: Empowering developers to scale projects without constraints. Over-the-air (OTA) Device Firmware Updates (DFU) with 1GB monthly bandwidth 1,000,000 Monthly Log Messages up to 200MB Free data retention Time series – 30 days Logs: 14 days The main limitations compared to paid plans are that only one project can be created and a single seat (single loading) is available, so it’s not possible to have a team of users with different permissions like […]

ePulse Feather C6 – An ESP32-C6 development board with Adafruit Feather form factor, LiPo battery support

ePulse Feather C6

ThingPulse ePulse Feather C6 is a new ESP32-C6 development board with WiFi 6, BLE5, Zigbee, Thread, and Matter connectivity that follows the Adafruit Feather form factor and supports LiPo battery charging through a charger IC and a fuel gauge.

Waveshare ESP32-H2-DEV-KIT-N4-M – A Low-cost ESP32-H2 development board going for $6.65

Waveshare ESP32 H2 DEV KIT N4 M Dev Board

The Waveshare ESP32-H2-DEV-KIT-N4-M is a development board based on the ESP32-H2, available for only $6.65 on Aliexpress, but you’ll also find it on Amazon and Waveshare’s official store. This is a significant price drop compared to last year’s official Espressif ESP32-H2-DevKitM-1 board, which was priced at $10 without including shipping costs and with a similar design. In 2021, Espressif Systems introduced the ESP32-H2 to the world. However, it wasn’t until 2023 that they released their first development board. Since then, there haven’t been many products built around this new module. Some exceptions include the Olimex ESP32-H2-DevKit-LiPo, LILYGO T-Panel, and the ESP Thread Border Router/Zigbee Gateway board, all of which feature the ESP32-H2 chip. Waveshare ESP32-H2-DEV-KIT-N4-M specifications: Wireless module – ESP32-H2-MINI-1 MCU – Espressif Systems ESP32-H2 32-bit RISC-V microcontroller at up to 96 MHz with 320 KB SRAM, 128 KB ROM, 4 KB LP memory, Bluetooth 5.2 LE/Mesh, and 802.15.4 (Zigbee/Thread/Matter) radios.
