While it's true that a Raspberry Pi can draw a relatively higher amount of current compared to low-power devices, such as LoRaWAN chips, they serve different purposes and have different capabilities. Let's explore both options:

1. Raspberry Pi:
- The Raspberry Pi is a versatile single-board computer capable of running a full operating system (such as Linux) and hosting a wide range of applications.
- It offers a powerful processor, generous RAM, storage options, and a variety of connectivity options (Ethernet, USB, Wi-Fi, Bluetooth, etc.).
- Due to its computational power and extensive features, a Raspberry Pi typically consumes more power compared to low-power microcontrollers or specialized chips.

2. LoRaWAN Chip:
- LoRaWAN (Long Range Wide Area Network) chips are designed specifically for long-range, low-power communication using the LoRaWAN protocol.
- These chips are optimized for low power consumption, making them suitable for battery-powered or energy-efficient applications.
- LoRaWAN chips often have limited processing power, memory, and connectivity options compared to a Raspberry Pi.
- They excel in transmitting small amounts of data over long distances, making them ideal for IoT applications that prioritize long-range communication and power efficiency.

If power consumption is a significant concern for your project and you don't require the extensive capabilities of a Raspberry Pi, using a LoRaWAN chip can be a viable alternative. However, it's important to note that LoRaWAN chips are specifically designed for low-power, long-range communication and may not provide the same level of processing power and versatility as a Raspberry Pi.

Raspberry Pi draws a lot of current. Maybe replace it with LoRaWAN chip?
