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 […]

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

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. Just like its predecessor called ePulse Feather, the ePulse Feather C6 is optimized for low power consumption but replaces an ESP32-WROVER-E-N8R8 module but an ESP32-C6-MINI-1 with a 802.15.4 radio for Zigbee, Thread, and Matter, as well as 2.4 GHz WiFi 6 and Bluetooth 5.3 LE connectivity. ePulse Feather C6 specifications: Wireless module – ESP32-C6-MINI-1 SoC – ESP32-C6H4 32-bit RISC-V microprocessor up to 160 MHz with 320KB ROM, 512KB HP SRAM, 16KB LP SRAM, 4MB flash Wireless – 2.4 GHz WiFi 6 with Target Wake Time (TWT) support, Bluetooth 5.3 LE and Mesh, 802.15.4 radio with Zigbee, Thread, and Matter PCB Antenna USB – 1x USB Type-C port for power/charging and programming […]

2×2 Quad Display Board uses Raspberry Pi Pico W or ESP32-S3-WROOM-1 module to drive four displays (Crowdfunding)

Raspberry Pi Pico ESP32-S3 quad display board

SB Components’ 2×2 Quad Display Board is an MCU development board fitted with either a Raspberry Pi Pico W board or an ESP32-S3-WROOM-1 module used to drive four small color displays in square or round shapes. The board specifically features either four 1.54-inch square TFT displays or four 1.28-inch round displays, a microSD card, an RTC with coin-cell battery holder, and a USB-C port for power and programming, plus a few buttons. It may feel like it’s coming out of the but-why-because-we-can department, but the company expects it to be used for signage, interactive displays, art projects, portable devices, data loggers, education, and more. 2×2 Quad Display Board specifications: Main control (one or the other) Raspberry Pi Pico W MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM Storage – 2MB QSPI flash Wireless – WiFi 4 and Bluetooth LE 5.2 USB – 1x Micro […]

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.

Spark Analyzer is a USB-C PD analyzer and power supply based on ESP32-C3 (Crowdfunding)

Spark Analyzer is an ESP32-C3-powered device built to streamline the process of developing and debugging USB-C Power Delivery (UCPD) solutions. The board’s design is simple, compact, and includes helpful power delivery and analysis functionality, at an affordable price. Spark Analyzer runs on an ESP32-C3FH4 microcontroller, a low-power SoC with a single-core RISC-V CPU with onboard 2.4 GHz Wi-Fi and Bluetooth 5 (Low Energy) connectivity. The wireless chip lets users control the Spark Analyzer and monitor its operation remotely. It also supports integration with other smart devices via Matter. The device allows you to adjust voltage output from 5V to 20V, depending on your project requirements. Power is sent to a connected device via the two-pin screw terminal block on the device, and a Cross Chip sensor measures the electrical current sent through the device using Hall effect. It includes a software safety feature that turns off the output field-effect […]

Waveshare R7FA4 PLUS A and B boards are clones of the Arduino UNO R4 Minima and WiFi

Arduino board clones have been around for many years, but I don’t think I have ever seen clones of the new Renesas-based Arduino boards so far. Waveshare changes that with the R7FA4 PLUS A that clones with Arduino UNO R4 Minima, and the R7FA4 PLUS B board duplicating the Arduino UNO R4 WiFi. The Waveshare boards are not 100% clones with some small differences in the PCB layout, support for 5V and 3.3V shields, an additional 6-pin “power output header” with 5V, 3.3V, and GND signals, and a USB communication jumper to select between the Espressif ESP32-S3 and Renesas RA4M1 microcontrollers. Waveshare R7FA4 PLUS A and B specifications: Microcontroller – Renesas RA4M1 Arm Cortex-M4F MCU @ 48 MHz with 32KB SRAM, 256KB flash Wireless (B model only) – ESP32-S3-MINI-1 module based on ESP32-S3 dual-core Xtensa LX7 microcontroller with 512KB SRAM, 384KB ROM, WiFi 4 and Bluetooth 5.0 connectivity, PCB antenna […]

ESP32-C6-Bug WiFi 6, Bluetooth LE, and 802.15.4 board takes a PoE Ethernet shield (Crowdfunding)

We’ve already covered a range of ESP32-C6 boards, but none supporting Ethernet and PoE so far, and the ESP32-C6-Bug board brings that to the table thanks to the Esp32-Bug-Eth shield with a W5500 Ethernet chip, an RJ45 jack and a PoE power module. Like other ESP32-C6 devices, the little board supports Wi-Fi 6, Bluetooth LE 5, as well as Thread and Zigbee through its 802.15.4 radio, but it also integrates some other interesting features such as castellated holes for easy soldering on a carrier board and support for LiPo batteries with built-in battery charging and protection circuits. ESP32-C6-Bug board specifications: SoC – ESP32-C6FH4 MCU cores 32-bit RISC-V core @ 160 MHz 32-bit RISC-V core @ 20 MHz low-power coprocessor can run tasks even when the main system is in deep sleep state Memory – 512 KB SRAM Storage – 4 MB Flash Wireless – WiFi 6, Bluetooth LE 5, and […]
