SparkFun RedBot Sensor - Accelerometer SF_3-axis we have an SWD connector

we have an SWD connector on board that can be used to reprogram the nrf51822 using Nordic's SDK and an SWD debugger like the J-Link

Note: While these are backwards compatible in many ways with the XBee 1s and 2s

This product is compatible with the Attopilot 90A Voltage and Current Sensor Breakout

which makes it easy to integrate this great sensor into your project
