AccessHAT

The AccessHAT makes access control integration for the Raspberry Pi simple and easy, with physical sensing, Wiegand integration, and more. Has to two relays to support two access points. Plug and play with Observables Cellular Module(CM). Multi-purpose Access/IO with cellular capability. Acts like a PoE HAT, a Relay HAT, a GPIO HAT, a Cell HAT, and a Sensor HAT all-in-one. Perfect for access control!

• Features

  • Wide input power supply filters and offers larger voltage range for array of powered applications.
  • On board LSM6DS33 offers a multitude of physical sensing ability for any movement oriented solutions by way of Accelerometer, Gyroscope, Temperature, and 6 Axis.
  • On board MCP7940 RTC offers the Pi's ability to keep time through offline power-down/up scenarios as well as set accurate calendar interrupts.
  • Observables Compatible Communications Module (CM) socket allows for diverse radio plug and play applications such as Cellular.
  • MAX3140 availability allows for RS485 system integrations and expansion.
  • Dual Latching relays allow for low-power/offline/No-power maintained control for up to 3A.
  • IO Expander TCA6424A with on board PU/PD resistors make for fast, simple Digital IO integrations for up to 9 IOs.
  • 2 Level shifted direct IO allow for such integrations such as Wiegand, or other longer range protocol/Level shifted IO for triggering internally or externally.
