RFCat N32 Long Range nRF52832 Bluetooth Board Delivers 30x the Transmission Power with an Amplifier

Bluetooth 5.0 has two main new features: high speed (2Mbps) and long-range. But as we’ve seen in our nRF52840 vs nRF52832 vs nRF52810 comparison is that only nRF52840 supports Bluetooth 5.x long range. Bluetooth 5 long range is achieved with two new lower bit rates of 500 kbps and 125 kbps. So what do you do if you’d like a longer range and keep using the higher bit rates? You add a power amplifier and LNA to your board, and that’s exactly what Nikolaj (RFCat) did with RFCat N32 board based on Nordic Semi nRF52832 wireless SoC. RFCat N32 board specifications: Wireless module – Meshtek-H52 Smart Mesh Module with integrated PCB antenna based on Nordic Semi nRF52832 Arm Cortex-M4F Bluetooth 5-ready SoC (See datasheet) Skyworks RFX2401C PA &LNA with 18.9dBm TX gain and 11dBm RX gain USB – 1x USB-C port for power, programming and debugging via CP2102N USB to UART bridge I/Os – 2x 13-pin 2.54mm pitch headers with […]

PoE FeatherWing Brings PoE, Unique MAC Address to Adafruit Feather Boards (Crowdfunding)

[Update: In the initial version of this post, Giant Board was wrongly attributed to Silicognition LLC (Patrick Van Oosterwijck). It was actually made by Groguard] Silicognition LLC (Patrick Van Oosterwijck)’s PoE FeatherWing is an expansion board that adds PoE support to Adafruit Feather boards and can handle up to 4 Watts of power. The expansion board also comes with a built-in globally unique MAC address. It’s similar to the official Ethernet FeatherWing, but with the addition of PoE and a unique MAC address. PoE FeatherWing key hardware features and specifications: WIZnet W5500 Ethernet controller up to ~13 Mbps Microchip 24AA02E48 2 Kbit serial EEPROM with built-in globally unique MAC address to avoid having to change and recompile the code for each device. Power Isolated IEEE 802.3at Class 1, Mode A and Mode B Power over Ethernet (PoE) with up to 4W of output power available via an RJ45 Ethernet port Output voltage – 4 to 5 V Dimensions – 55.9 […]

The Visible Lisp Computer Runs on Adafruit ItsyBitsy M0 Board

Specified in 1958, Lisp is one of the oldest programming languages, and it does not appear to be widely used anymore. But if you want to play around with the 61 years old language, you may want to do so in a neat way via the Visible Lisp Computer, a Lisp interpreter that displays the contents of the Lisp workspace on an OLED display. It is a modified version of Technoblogy’s uLisp interpreter for Arm boards designed to run on  Adafruit ItsyBitsy M0, or other boards based on Microchip ATSAMD21E MCU on a prototyping board, connected to a 64×48 OLED display over I2C. uLisp gives you a workspace of 3072 free Lisp objects (each of 8 bytes) on this hardware, which exactly matches the 3072 pixels (64×48) from the display.  Having said that the program would also work on larger SSD1306-based OLED displays. The display shows free Lisp objects in black, and when an object is in use the corresponding […]

$10 Wio Lite W600 Arduino Zero Compatible WiFi Board Follows Adafruit Feather Form Factor

Seeed Studio has just released the latest Arduino compatible Wio Lite W600 a combination of the W600 WiFi module mounted on the board and an Atmel  SAM D21 Arm Cortex-M0+ microcontroller. The WiFi core is a W600 2.4 GHz module featuring the Arm Cortex-M3. The SAM D21 is the same chip used by the Arduino Zero, so the Wio Lite W600 is compatible with Arduino Zero. Basic Specs The I/O level is 3.3V, and there are 6 analog pins and 14 digital pins, as well as one UART, I2C, and ICSP port. The board is powered through a USB Type C port or a 3.5V–4.2V LiPo battery. The latest feature is the W600 module is CE/FCC certified and supports 802.11 b/g/n WiFi. The WiFi module also features 1MB on-chip flash to store and run freeRTOS operating system. Seeed Studio provides a full Arduino W600 library and demos for many wireless access point options on Github. The New Wio Lite Series […]

Icarus IoT Board Features nRF9160 GPS + NB-IoT SiP in Adafruit Feather Form Factor

The new Icarus IoT board from Actinius, uses the Nordic nRF9160 SiP, a powerful yet low power system in a package designed for use with GPS and LTE-M & NB-IoT cellular data, also found in Ruuvi node which we covered a few months ago. The board’s purpose is for mobility and ease of project tracking anywhere, and can be found in application scenarios such as fleet management and security, cargo tracking, or asset monitoring, and many more. The board has power inputs for solar panel, USB or LiPo/Li-Ion Battery, which widens the boards mobile nature, and on-site, in-the-field capability. Since the form factor follows Adafruit Feather, the Icarus board benefits of additional component options for prototyping and DIY electronics projects. The nRF9160, by Nordic Semiconductor, is a SiP (System in a Package) that carries an extensive line of embedded software and hardware. As we had reported the nRF9160 SiP low-power IoT solution consists of a global multimode LTE-M/NB IoT modem, […]

A List of Cellular IoT Development Boards

We’re starting to have a decent choice of cellular development boards, and as the number of products is getting larger having some sort of list would be useful. That’s exactly what Hologram has done. While the list is not quite exhaustive, they’ve pushed the csv list to Github, and plans to update it. Hologram also encourage pull requests, so manufacturers may consider updating it with their own boards. The list focuses on development boards acting as cellular IoT end points, so you won’t find gateways, WiFi hotspots, end user devices and modules that needs to be soldered onto your own board. I have imported the list to WordPress to make it searchable, let people select the number of rows to display, and customize visible fields. The table is not automatically synchronized, so for the latest version always check out Github. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering […]

ESP32 Updates – ESP32-S Module Replaces ESP3212, ESP32 DevBoards for Sale, Arduino & NodeMCU Support

There have been some developments with regards to Espressif ESP32 in the last month since my post about upcoming ESP32 development boards. First ESP3212 module is no more, and has been replaced with ESP32-S module with about the same features, but it’s not pin-to-pin compatible, so the new module won’t work with older breakout boards made for ESP3212. ESP32-S is now out of stock on Seeed Studio, but you’ll find it on IC Station, Banggood, and others shops. One good news is that it’s now easier to buy – or at least pre-order – ESP32 development boards, although stock may still be an issue, as the platform is very popular. If you live in the US, you can now backorder “Sparkfun ESP32 Thing” for $19.95. ESP32 board can be powered by either a micro USB power supply or a LiPo battery, and exposes close to 30 I/O pins. ESP32 developer board is still listed on Adafruit for $15, but you […]
