Minibat is a simple battery-powered carrier board designed to host a panStamp and one or multiple sensors. Minibat can also be used as a DIP adapter for panStamp and is pin-compatible with other mini-carrier boards made by the company. This means that minibat can be stacked on top of a panStick or plugged onto a bread board during the prototyping process.

PCB antenna

The board comes with a printed PCB meander antenna. This antenna is designed for 863-873 MHz and 902-928 MHz and can be enabled on bare minibat boards by bridging L1 between the panStamp module and the antenna:

Meander antenna enabling bridge

This is only necessary for bare boards. Minibat boards preassembled with any sensor option already includes a 0 Ohm resistor providing this bridge.
