The Oshchip works great, even under less ideal settings (such as being surrounded by a thick metal case, while being located about 5 meters from the mobile phone). I didn't have previous experience using Nordic products & Keil IDE, and Philip has provided unbelievably helpful and kind support and instructions regarding how to best use and program the Oshchip using Keil IDE.
International shipping went flawless and the items were packed very well and arrived in good conditions. Thank you!
I used these to make a small board that pops into a 28-pin DIP socket. Works like a charm and so much nicer than any other solution out there. Highly recommended. I think these would also be great for Wifi modules or anything else that comes in the breakout board format.
