Arduino “launches” WisGate Edge LoRaWAN gateways in collaboration with RAKwireless

Arduino was already involved in LoRaWAN with its MKR WAN 1300 board, but now the company has started offering Arduino-branded Wisgate Edge Pro and Wisgate Edge Lite 2 LoRaWAN gateways for respectively outdoor and indoor environments as part of the Arduino Pro family. If the names of the gateways seem familiar, it’s because Arduino collaborated with Rakwireless, and is simply using their existing LoRaWAN gateways. As I understand it RAKwireless will provide the hardware and technical support, while Arduino will sell the gateways and other LoRaWAN hardware through its existing customer base, more acting as a distributor. Arduino WisGate Edge Lite 2 indoor gateway specifications: SoC – MediaTek MT7628 MIPS processor @ 580 MHz System Memory – 128MB DDR2 Storage OS on flash SD card for setup and diagnostics, backup, and data logging Connectivity 10/100M Ethernet RJ45 port 2.4 WiFi (802.11b/g/n) with -95 dBm RX sensitivity, 20dBm Tx power; internal […]

Espressif unveils “One-Stop Matter Solution” for ESP32 wireless SoC’s

Espressif Systems have announced their one-stop Matter solution that features their ESP32, ESP32-C, and ESP32-S series wireless microcontrollers with WiFi and/or Bluetooth LE connectivity, as well as the ESP32-H series with an 802.15.4 radio for Thread and Zigbee connectivity. Matter, which was first introduced in 2019 as Project CHIP, aims to improve interoperability among Smart Home products, has a focus on security, and the protocol is supposed to work on top of the most popular communication standards like Ethernet, Thread, 802.15.4, WiFI, Bluetooth, and so on, but more on that later. The first commercial products with support for Matter are scheduled for the end of the year, so all major vendors of wireless chips have already introduced Matter-ready solutions including NXP, Silicon Labs, Nordic Semi, and others. Espressif had actually already talked about Matter support with the announcement of the ESP32-C2 chip. But the recent announcement targets all Espressif’s ESP32 […]

Seeed Studio outs $5 XIAO ESP32C3 board with WiFi and BLE, battery support

Seeed Studio’s XIAO family of tiny MCU boards expands with the XIAO ESP32C3 board equipped with ESP32-C3 WiFi and Bluetooth LE (BLE) microcontroller, support for LiPo batteries, and following the same 21 x 17.5mm form factor. If I’m counting right, this is the fifth member following the original XIAO based on Microchip SAMD21G18 Cortex-M0+ MCU, XIAO RP2040, and the nRF52840-based XIAO BLE and XIAO BLE Sense boards which I tested with Edge Impulse. XIAO ESP32C3 specifications: Wireless MCU – Espressif Systems ESP32-C3 single-core RISC-V microcontroller @ 160 MHz with 400KB SRAM, 384KB ROM, 4MB flash Wi-Fi 4 & Bluetooth LE 5.0 connectivity Antenna – External u.FL antenna USB – USB Type-C port for power and programming Expansion I/Os 2x 7-pin headers with 1x UART, 1x I2C, 1x SPI, 11x GPIO (PWM), 4x ADC, I2S 3.3V I/O voltage (not 5V tolerant) Debugging – JTAG pads Misc – Reset button, Boot button, […]

LILYGO T-QT V1.1 – A cute little board with ESP32-S3 and a 0.85-inch color display

LILYGO must be churning out at least one new “ESP32” board every month, but I don’t think they’ve ever made one with ESP32-S3. LILYGO T-QT V1.1 board changes that and combines the dual-core WiFi 4 and Bluetooth LE 5.0 AI microcontroller with a 0.85-inch color display. The board also happens to be rather small and cute with a 33 x 18 mm form factor, offers some I/O via headers and a 4-pin connector, and can be powered via its USB Type-C port or a battery, but lacks a charging circuit. LILYGO T-QT V1.1 specifications: Wireless MCU – Espressif Systems ESP32-S3 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, wireless connectivity Storage – 8MB flash Connectivity via ESP32-S3 2.4 GHz 802.11 b/g/n Wi-Fi 4 with 40 MHz bandwidth support Bluetooth Low Energy (BLE) 5.0 connectivity with long-range support, up to 2Mbps data rate.

Getting started with WiFi on Raspberry Pi Pico W board

Raspberry Pi Trading announced the Raspberry Pi Pico W board basically based on the same design as the original Raspberry Pi Pico board with RP2040 dual-core Cortex-M0+ microcontroller but adding a wireless module with WiFi 4 and Bluetooth LE 5.2, although the latter is not enabled on the board at this time. The company sent me a sample for review/evaluation, and I’ll focus on the WiFi part since the Raspberry Pi Pico W supports the same MicroPython and C/C++ SDKs as for the Raspberry Pi Pico board plus additional APIs for wireless connectivity. Raspberry Pi Pico W unboxing The board I received was cut from a 480-unit reel, and I also got a one-meter long micro USB to USB cable, which should probably not be included by default for people ordering the $6 board. Just like its predecessor, the board is tiny, and The pinout is the same as the […]

Raspberry Pi Pico W – A $6 Raspberry Pi Pico board with WiFi 4

I was expecting the next official Raspberry Pi board to be either an update of Raspberry Pico with WiFi and Bluetooth or with a machine learning accelerator and the new $6 Raspberry Pi Pico W delivers that wish through the addition of 2.4GHz WiFi 4. Having said that, I was actually expecting a competitor to ESP8266 or ESP32 with a new Raspberry Pi wireless microcontroller, but it did quite happen that way as the Raspberry Pi Pico W features the same Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller found in Raspberry Pi Pico board coupled with an Infineon CYW43439 chip that’s supposed to support both 2.4 GHz WiFi 4 and Bluetooth LE 5.2. Bluetooth is not enabled right now, but may be at a later stage. Raspberry Pi Pico W specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz with 264KB SRAM Storage – 2MB QSPI flash Connectivity […]

NORVI GSM industrial controller with WiFi and cellular connectivity supports Arduino or ESP-IDF programming

NORVI GSM ESP32 cellular industrial controller

We’ve already seen ESP32 WiFI & Bluetooth SoC combined with a cellular modem several times already, and a couple of days ago, I wrote about LILYGO T-A7068X ESP23 board with a 4G LTE modem. Iconic Devices team has made another cellular ESP32 product with the NORVI GSM industrial controller. The DIN-Rail mountable USB programmable controller is offered with a choice of SIMCOM SIM800L 2G-only modem or QUECTEL EC21-G modem adding 3G UMTS/HSPDA+ and 4G LTE cellular connectivity. It also offers Ethernet connectivity, digital and analog inputs, relay outputs, and a small 0.96-inch OLED information display with options varying depending on the exact model. NORVI GSM specifications: Main module – ESP32-WROOM-32 with ESP32-D0WDQ6 dual-core microcontroller @ up to 160 MHz with 520 KB SRAM, 4 MB flash, 2.4 GHz WiFi 4 and Bluetooth 4.2 connectivity Cellular module (one or the other) SIMCom SIM800L quad-band GSM/GPRS module Quectel E21-G worldwide 4G LTE, […]
