A PoE hat for the Raspberry Pi 3B+ single board computer with mini PCIe Slot and optional GNSS module.

Highlights

  • Supports 10/100/1000MBit/s ethernet speeds
  • IEEE 802.3af compliant
  • Low profile and thus compatible with many standard RPi enclosures
  • Supports stacking (adding other hats on top of it)
  • Overload protection
  • 7 W power delivery
  • Mini PCIe slot with SPI/ UART signals routed to RPi header
  • Power good LED
  • Temperature sensor LM75B
  • High efficiency enabled by Schottky diode bridge rectifier
  • Non-standard SPI connectivity between mPCIe header and RPi SP0 bus
  • Optional USB on mini PCIe slot through JST connector to wire
  • Optional GNSS module
  • Optional nano SIM card holder
  • No power issues like the original PoE hat had

Application

The device can be used to reliably power the Raspberry Pi through PoE. The temperature can be monitored and an mPCIe card can be plugged in. The optional GNSS module is connected to the I2C bus of the RPi. Combining this with an LRWCCx-MPCIE card and a proper enclosure turns the solution into an LoRaWAN™ gateway.

Wiring Up USB

USB is not available on the RPi’s 40 pin header, if you need USB on the mPCIe port, the following modification is required:

  1. Remove solder bridges R8, R9.
  2. Solder the wires of a JST 1.25 mm pigtail as follows to the test pads on the backside of the raspberry Pi: 46 to D- (red) and test pad 47 to D+ (black).
  3. Connect the JST connector to the connector designated with ‘USB’.

WARNING: This will void the warranty of the RPi and you risk fatal damage to the devices.

Kit Contents

  • SBCPoE RPi3B+ mini PCIe Hat
  • 2x Torx mounting screws for the mini PCIe slot
  • 2x nylon standoff spacers

Usage

  1. Disconnect any power source from the Raspberry Pi and leave it disconnected when using the hat
  2. Insert the standoff spacers and snap on the hat
  3. Connect a 802.3af compliant PoE injector (usually an ethernet switch) to the RPi ethernet jack
  4. to read the temperature from the temperature sensor, follow this guide.
