Good morning, my name is Marco Russi and I live in London, UK.
I am a contract/freelance embedded software engineer with 10 years of experience. I have been involved in projects mainly for smart sensors, actuators control and battery powered devices. I have already worked with a few companies in UK designing and developing firmware and software or following an entire embedded system development, including hardware, from requirements to first prototype and then to production.
My main experience is on Bluetooth Low Energy applications based on Nordic nrf51 devices but I also have a good knowledge of WiFi, Ethernet...
Algocraft expands the device list by adding the nRF52832 Microcontroller produced by Nordic Semiconductor.
WriteNow! uses the Serial Wire Debug protocol (SWD), which is the most common protocol for device’s programming. The default communication frequency is 8MHz, but it could be set up to 10MHz.
Algocraft provides support of nRF52 to all of its WriteNow! Series, single and multiple In-System Programmers. We offer four models: WN-PRG01A (programs 1 device at a time), WN-PRG02A (programs 2 devices in parallel), WN-PRG04A (programs 4 devices in parallel), and WN-PRG08A (programs 8 devices in parallel). In addition, external demultiplexer modules are available as...
The Auto-DFU Lite for OSX is Available on the App Store.
Remark: Support the Legacy DFU service Only.
nRF52832 + LNA + PA Range Extension EV-Board
Ø Improved Receiver sensitivity with 12dB gain LNA Ø Increased Transmitter output power up to +20dBm Ø Extended Receiver dynamic range Ø Enhanced Antenna coverage through Antenna diversity（Dual Antenna support）
This is also best sol for the coming Bluetooth 5.0 and Mesh network.

I wanted to share a link to a Kickstarter campaign that we are currently running: https://www.kickstarter.com/projects/scribeformakers/scribe-for-makers-integrated-10-axis-motion-sensin
In the development of our running sensor (RunScribe) we have received a lot of requests for other applications, so we thought that we would open it up for other (non-running) applications. My hope being that between the top shelf components and an integrated rechargeable all in a small, durable package would be enabling for a lot of other developers.
Thanks for looking! Tim
Hi! We are the developers of Mongoose, the most popular embedded networking library.
Recently, we have ported it to nRF51 / nRF52 - see step-by-step demo at: https://www.hackster.io/dfrank/mongoose-embedded-networking-library-on-nrf52-547b15
Now, the rich set of networking API - like HTTP/WebSocket/MQTT/mDNS/CoAP, is available on Nordic chips. Official SDK lacks support for some widely used protocols like HTTP and WebSocket, and Mongoose provides it!
What Mongoose can do? Turn a device into a RESTful server - make it controllable via a browser! Or, call an external RESTful server. Or, create a Web UI for a device. Push data in...
Hi everyone. I'm pleased to introduce MOBILIAN nRF5x mass production solution.
When you finished development with nRF5x and decided production, how do you program your target device? There are several solutions that you can imagine.
So I introduce you fast & cost effective HW...
We have designed one offline programmer for nRF5x chip,it can program the flash of nRF5x easily.
The picture of programmer is as follows:
also you can view the picture from: https://goo.gl/photos/aaA3RDHacaSHEDm29
The guide document can be downloaded from http://pan.baidu.com/s/1eRaAGEm
also you can download it from: https://drive.google.com/file/d/0ByxGwj7TyzfXRk4xSU1Dbkk3aXkybWl0V3kyamlVdTBCcmI4/view?usp=sharing
If you have any question about the programmer ,please contact us by email email@example.com ,or firstname.lastname@example.org
Here's a link to the EagleCAD files for a QFN48 socket to J-Link/JTAG 20-pin connector to program bootloaders, etc for Nordic nRF51:
I included a USB connector as an alternative to using the 5V power from the J-Link, but haven't had to use that yet; the power from the J-Link device works great!
I also included a 16MHz crystal in the design so that I could boot up the nRF51 and do some basic validation. Probably could get away without populating those or related components.
The socket is available on Amazon.com...
The NRF51822 Bluetooth Low Energy mbug board from y5 Design is an easy to use ARM Cortex-M0 microcontroller with BLE. This board can be used as a standalone system or stacked with other mbugs to create multifunctional systems.

Are you looking for a RTOS and Tickless technology nRF51822 module ?
Now, We already sell the LilyPad for nano51822 on AMAZON.
More information please see our web site.
The IDAP-Link is a very low cost CMSIS-DAP JTAG debug probe with enhanced features. It can do more with it than just debugging. It will appears as a USB disk drive. This allows firmware flashing easily by copying the firmware file over without requiring any special flashing software and work instantly with any operating system. It provides a UART to USB bridge for communication between the target device and the PC. It also provides a regulated 3.3V...
