Key Features: XBee 3 not only handles 802.15.4, and ZigBee, but also BLE protocols and you can now talk to the modules over UART or SPI as well 200ft indoor range, or 4000ft outdoor/line-of-sight range Built in microcontroller to configure and program the modules using MicroPython as well as Digi's XCTU software HCS08 CPU running at up to 50.33MHz, 15x digital I/O pins, and 4x 10-bit ADC pins After years of popularity with the XBee Series 1 and XBee Series 2, SparkFun now has the XBee Series 3 which brings the best of both worlds. XBee 3 not only handles 802.15.4, and ZigBee, but also BLE protocols and you can now talk to the modules over UART or SPI as well. With a 200ft indoor range, or 4000ft outdoor/line-of-sight range, you can set up a mesh network to talk to or communicate with various devices around your house, work, or other area.This module has the familiar XBee package while sporting a PCB Antenna. You also get a built in microcontroller so you can also configure and program the modules using MicroPython as well as Digi's XCTU software. With a HCS08 CPU running at up to 50.33MHz, 15x digital I/O pins, and 4x 10-bit ADC pins these modules can even hold their own as a microcontroller.Item Specifics1 - Xbee 3 ModuleRF 250Kbps, Serial 1MbpsRange: 200ft (indoor) to 4000ft (outdoor) rangeTransmit power +8dBM @ 40mAReceiver Sensitivity: -103dBm @ 15mACPU: HCS08 @ up to 50.33MHzEncryption: 128/256 bit AESOperating Voltage: 2.1V to 3.6VPower-down Current: 1.7 μABuilt in RS-485 supportAT command or API frame supportFCC/ETSI CertifiedRequires competency in electrical prototyping and programming.
