Finally upgraded the previous HP 8753D with a 6GHz model.
And as an added bonus, I've acquired the pieces to turn it into a non-011 unit. I'll post back once the mod is complete.

For kicks, we tore down a popular BTLE (Bluetooth smart) module. Pretty straightforward layout; wished they'd broken out a few more I/O. Note that the metal can has been removed.
They use a fractal antenna ... for cost savings, I'm not sure why they didn't go with an IFA, or maybe even a PIFA.

Saw this at some big chain store recently, so I decided to buy one ($39) and tear into it. Uses a TI CC2541 based BLE module from ILOGICTECH ...and they may or may not have written the App (Perfect App in the iTunes App store) that goes with this accessory. Not the sleekest design, nor the best app, but for 40 bucks, it's okay. Assembly of the unit and build quality of the board is average.
Not pictured was the small 9 conductor ribbon cable between the main board and the LCD board. This unit also has a small E2PROM for 14 days worth of data storage, and a small 3 axis accelerometer (part making BOM7A ... looks to be I2C comms).

Since I published the Nordic Smart Beacon, I thought I'd show off what we've been playing with for the past 9 months or so. We've used this same design to do various types of demo sensors. The unit pictured is of a Sensiron SHT21 humidity sensor interfaced to the nRF51822.

Purchased these a few weeks ago, and have been toying with them. Nice.
