SparkFun Thing Plus - XBee3 Micro Chip Antenna

Description
The XBee3 Thing Plus is an ultra-capable and easy way for getting into wireless device development. The combination of XBee and Qwiic in a space-conscious design represents a much-needed update to our XBee offering. With 20 I/O pins and Lithium-Polymer Ion battery management， the XBee3 Thing Plus has all the basics for quickly prototyping or developing a connected device such as a remote sensor. The Qwiic connector and JST connector for the battery make for a solder-less option when working with the board which shortens setup time.
The new XBee3 Micro Module provides the classic， near plug and play 802.15.4 2.4GHz wireless connection(Zigbee 3.0 Protocol)that makes it so desirable， but with a new addition of being programmable with MicroPython(32KB of memory available for it). RF data rates up to 250Kbps and 200 ft indoor ranges and up to 4000 ft line-of-sight outdoor range. Communicating with/Configuring the module happens via an AT Command set or the Digi API， X-CTU， both locally or over-the-air. There's even a mobile version of X-CTU now； Digi XBee(R)Mobile.
Note：This variation uses a chip antenna and is not compatible with external antennas.
