XBee Board. Includes 2.54mm screw terminals for two sensors.
1. One is active low, using the xbee pullups. This is a two wire hook-up, simple switch (DIO and ground).
2. One is powered and assumed active high, with internal sensor pulldowns. This is three wire hook-up (DIO, positive, ground).
3. Micro USB connector to provide power only.
4. LEDs for power and RSSI.
5. Works great.
6. Use one on my mailbox under battery power with one reed switch.
7. Leave the power LED unpopulated for better battery life.

1. Uses an ATTiny 25/45/85 8SOIC to control common LEDs (WS2801 or APA102).
2. Reset button advances sequence in code, with pins included for additional remote reset button.
3. Program with 8SOIC Test clip, there are no ICSP pads.
4. This is very small.
5. Works just fine 3.3V and 5V. One Li-Ion battery is perfect.
6. I am using these in various projects. With a 20 mhz resonator they can do some impressive POV effects in flow toys (poi/staff).
