ACubes A3T Device specification |
KEY FEATURES
- Perfect solution for educational projects and learning
- Compatibility with A3R modules
- Low power consumption (Idle/Tx) 20 mA / 0.5 A
DESCRIPTION
ACoubes A3T is a pulse acoustic single-frequency transmitter module controlled by a digital line. The device can be combined with the A3R receiver module and share a single acoustic transceiving antenna. The device can also be stacked (up to 12 units) with A3R receiver modules. In this case, each receiver and transmitter uses a separate antenna.
The following antennas can be used:
- RT-1.332820-1 - affordable solution with minimal dimensions
- RT-2.332820-1 - dual-element antenna with enhanced sensitivity for surface operation
- RT-1.524525-1 - antenna with enhanced sensitivity
