minibat board
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.
Minibat has the same pinout as the rest of mini-carrier boards. This means that minibat can be stacked under (or onto) other carrier boards, as far as only one of the carrier boards has a panStamp module assembled.
Starting from minibat 2.0 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:
This is only necessary for bare boards. Minibat boards preassembled with any sensor option already includes a 0 Ohm resistor providing this bridge.
- Size: 1.0 x 2.2 in (25.4 x 55.8 mm)
- Pin spacing: 0.1 in (2.54 mm)
- Optional on-board sensors:
- 10KOhm NTC temperature sensor
- SI7021 I2C humidity/temperature sensor
- BMP180 I2C pressure/temperature sensor
- MMA8652FC I2C 3-axis accelerometer (minibat 2.0 only)
- Voltage supply: 2.0 to 3.6 VDC
- PCB meander antenna for 863-873 MHz and 902-928 MHz (minibat 2.0 only)
- Footprint for optional U.FL antenna connector and wire antenna (minibat 2.0 only)
Minibat works with different sample sketches, depending on the sensor mounted on the board.
