SX1262 LoRa Node Module for Raspberry Pi Pico, LoRaWAN, 915Mhz

Jargon buster

Plain-language definitions for the technical terms used above.

LoRa

LoRa is a long-range, low-power radio technology often used for telemetry and remote sensors. It matters here because the connector and pinout are compatible with some LoRa telemetry products, even though this module uses Bluetooth instead.

MCP73831

A lithium battery charger chip used to safely charge a single-cell LiPo battery. It matters because it lets the board recharge a battery from USB or another input without needing a separate charger module.

RF

RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.

SPI

A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.

Temperature compensation

Temperature compensation means the sensor adjusts its readings to reduce errors caused by changes in water temperature. This matters for field monitoring because ponds, rivers, and tanks can vary in temperature throughout the day and across seasons.
