How long does a Raspberry Pi + LoRa HAT last on battery?
At about 500 mA average draw, a Raspberry Pi + LoRa HAT runs roughly 0.3 days on a 3000 mAh 18650 cell and 0.8 days on a 10000 mAh pack. Real-world life depends on transmit duty cycle, screen and Bluetooth use.
What is the range of a Raspberry Pi + LoRa HAT?
With the stock 2.15 dBi antenna at 5 m, the theoretical line-of-sight range is about 14.3 km. In practice terrain and obstacles reduce it; raising the antenna is the single most effective improvement.
Is the Raspberry Pi + LoRa HAT good for a solar node?
It can work, but at ~500 mA average draw it needs a bigger panel and battery than nRF52840-based boards (≈12 mA).
