Nordic Semi nRF52840 Bluetooth 5.2 LE module achieves over 10 km range

Fanstel BT840XE is an nRF52840 Bluetooth 5.2 LE module with a power amplifier designed for transmission at over 4500 meters, and some deployments with two BT840XE modules and 0Dbi antennas even reach over 10 km. At home, I can use my Bluetooth headset about 6 to 8 meters from my phone before the audio starts cutting, and most Bluetooth devices have an advertised 10-meter range, although Bluetooth class 2 devices could transmit up to 100 meters away. But with Bluetooth 5, the wireless standard improvement meant it was not possible to get four times the range, and/or some further extended the range of their hardware with a power amplifier as we’ve seen with the RFCat N32 board a few years ago. Last week, I got contacted by a company called RF Star about a Texas Instruments CC2652P multi-protocol mobile with PA (power amplifier) that could achieve a range of 500 […]

RAKwireless adds more Wisduo and Wisblock modules, launches WisToolBox configuration tool for IoT devices

RAKwireless have launched several Wisduo wireless modules, a dozen of Wisblock modules for IoT prototyping, updated WisDM, WisGateOS, and RUI3 software, and introduced WisToolBox mobile/desktop configuration tool for IoT devices as part of their spring launch 2022 even entitled “Empowering the Innovators: Making IoT your own”. Three new Wisduo modules RAK3172-SIP WisDuo SIP based on STM32WLE5 Wireless SoC with LoRa connectivity. Compared to the original RAK3172, it offers more IO pins, integrates a TCXO, and comes in a smaller size. The module supports LoRa P2P and complies with Class A, B, & C of LoRaWAN 1.0.3 specifications. Cost: $5.99. WisDuo RAK3272-SiP – That’s a breakout board for the RAK3172-SiP System-in-a-Package module for LoRaWAN and allows easy access to all pins via 2.54mm pitch headers. RAK4630 WisDuo Stamp Module – This module supports both LoRa/LoRaWAN and BLE 5.0, and comes with RUI V3 (RUI3) firmware. It can be deployed as an […]

Ai-Thinker Ra-08 LoRaWAN module features ASR6601 chip (Sponsored)

Ai-Thinker Ra-08/08H are new LoRaWAN modules based on ASR Microelectronics ASR6601 module featuring a 48MHz ARM Cortex M4 microcontroller and Semtech SX1262 transceiver allowing long-range, low power communication for the Internet of Things. Both LoRaWAN modules share most of the same specifications, but the Ra-08 module operates in the 410-525MHz frequency band, while the Ra-08H module works in the widely used 803MHz to 930MHz band. Ai-Thinker also provides a development kit for each module. Ai-Thinker Ra-08/Rs-08H key features and specifications: Programmable embedded Arm Cortex-M4 MCU with 128 KB of Flash and 16 KB of SRAM LoRa radio Sensitivity – -138 dBm @ SF12/125KHz Tx power – Up to +22dBm Frequencies Ra-08 – 410 MHz to 525 MHz Ra-07H – 803 MHz to 930 MHz Spread spectrum factor – SF5, SF6, SF7, SF8, SF9, SF10, SF11, SF12 LoRa, (G)FSK, BPSK, and (G)MSK modulation Bit rate up to 62.5 Kbps in LoRa […]

Pockit modular Linux computer gets a Raspberry Pi CM4 upgrade

We first wrote about the Pockit modular Linux computer with hot-plugging magnetic blocks about a year ago. The system was based on a STM32+ESP32 mainboard with a socket for an optional Raspberry Pi Compute Module 3 and included magnets and electrical contacts to snap and hot-plug modules/blocks while the computer is running. The developer (Anil Reddy) has made good progress with the project and added the option to use a Raspberry Pi CM4 with Pockit (provided you can find one) to improve performance, for example for computer vision. Other changes include support for AI accelerators, an improved dashboard, home automation integration, and more. Pockit now supports over 80 feature BLOCKS ranging from a rotary encoder to a microSD card reader to various camera types, an HDMI block, AI accelerators, and so on. All of which can be magnetically snapped while the computer is running, and automatically detected in the dashboard. […]

M5Stamp C3U IoT module relies on ESP32-C3’s own USB interface for firmware programming

M5Stamp C3U is an update of the M5Stamp C3 RISC-V IoT module with heat-resistant cover, support for WiFi 4 and Bluetooth 5.0, that does without CH9102 USB to TTL chip, relying instead on the internal USB interface of ESP32-C3 processor to handle serial programming of the firmware, and gaining on extra GPIO pin in the process. While several ESP32 processors come with a built-in USB interface, many boards still use an external USB to TTL chip such as CH340 or CP2102 to handle the serial interface used for debugging and flashing the firmware likely because of limitations when using ESP32-C3’s USB serial/JTAG controller console, but M5Stack probably considered those to be workable, and the small cost-saving beneficial. M5Stamp C3U specifications: WiSoC – ESP32-C3FH4 32-bit single-core RISC-V processor @ up to 160 MHz, with 384KB ROM, 400KB SRAM, 8KB RTC SRAM, 4MB embedded flash, WiFi and Bluetooth Connectivity 2.4 GHz WiFi […]
