Nano Signal Slot

GPIO Pin Spec

NanoPi NEO Plus2. The NanoPi NEO Plus2 is another Allwinner based ARM board developed by FriendlyElec. It uses Allwinner's 64-bit quad-core A53 SoC with hexa-core Mali450 GPU and features 1GB of DDR3 RAM and 8GB eMMC. The challenge of using nano-satellites as UHF communications relays is the integration of an inherently large antenna with a tiny satellite. The wavelength of the UHF signal can be up to ten times the size of the nano-satellite.

Nano Signal Slot App

  1. SYS_3.3V: 3.3V power output
  2. VVDD_5V: 5V power input/output. When the external device’s power is greater than the MicroUSB's the external device is charging the board otherwise the board powers the external device. The input range is 4.7V ~ 5.6V
  3. All pins are 3.3V, output current is 5mA
