RFID reader can read several tags at a range of up to 60cm

The SparkFun Simultaneous RFID Tag Reader has numerous features that make it a huge leap forward over other RFID readers. The greatest feature is that the SRTR is able to read multiple tags at the same time. Additionally the read distance of tags is greatly increased from other readers and you can write your own data to the tags. This board will read EPCglobal Gen 2 tags at up to 150 tags per second. Writing of tags is also possible at 80msec standard write. The board has adjustable power output from 0dBm to 27dBm, meaning that with an external UHF RFID antenna you can read up to 5 m, or up to 60 cm with the onboard antenna. The reader is designed to work either with a USB to Serial connection to a computer or as a shield to an Arduino-compatible board.

Version 2 of the popular BLE Nano board has the new Nordic nRF52 chipset

BLE Nano is a very small Bluetooth Low Energy (BLE) development board. Nano 2 is designed as a 'drop-in' replacement, with exactly the same form factor, and in most instances no need to change firmware code. In addition, the new development board also offers a U.FL connector for an external NFC antenna, while you will benefit from the extra processing power and hardware resources of the nRF52832 SoC. To program Nano 2 you need the DAPLink v1.5 USB board, which is part of the BLE Nano Kit. Software development can be done by using Nordic's SDK, mbed.org or RedBear's open source Arduino Library for nRF5x. You can use the Nordic Apps for iOS and Android.

Bring your development board to life with the new TeensyView

The SparkFun TeensyView brings you an easy way to add a small, white-on-black OLED to your Teensy development board. The 128x32 monochrome display is controlled with the popular SSD1306 IC, and is a great way to display debug information and to visualize data. The board matches the Teensy 3 form factor perfectly. Since this is a headerless board, you have the option to solder on whatever type of header best fits your needs.
