This is a great board and makes experimenting with the xBee very easy. But I do have to agree… a “reset switch” is pretty much necessary when you start playing around with differnet firmware/command sets. Something like the “Mini Push Button Switch sku: COM-00097” would be perfect (leads could be bent flat for surface mount on the bottom of the PCB so you’re using a part you alrady stock.

Just a couple comments. The pin numbering on the schematic in the link above is incorrect. (e.g., A0 should be pin 6.)
I also agree the address pin should be brought out in the Breakout Board. Per the datasheet, the Device Address Selection pin can be tied to VSS or VDD, or can be actively driven by the digital logic levels. The logic state of this pin determines what the A0
bit of the I2C address bits should be.
Alternately, SparkFun could offer four different versions of the Breakout Board (by just changing which MCP4725 is soldered to it) or offer just the PCB with the two resistors and the cap pre-soldered and offering the DAC separately.
Part Number Address Option Code
MCP4725A0T-E/CH A0 (00) AJNN
MCP4725A1T-E/CH A1 (01) APNN
MCP4725A2T-E/CH A2 (10) AQNN
MCP4725A3T-E/CH A3 (11) ARNN
OR, it’s easy enough to simply swap the 6-pin SOT-23 DAC chip.
Anyway, thank you again SparkFun for an awesome Breakout Board.

Yes, the ATS177 is a latching sensor that requires a reverse field to turn it off.
I would like to see the Allegro A1301EUA-T Hall Effect Sensor. It is a continuous-time, ratiometric, linear Hall-effect sensor optimized to accurately provide a voltage output that is proportional to an applied magnetic field. It has a quiescent output voltage that is 50% of the supply voltage and provides 2.5 mV/G.
