NTR08 LoRa Transceiver Module Driver (STM32)
Budget: $30 – $250 USD
We need a clean, STM32-friendly driver for the NTR08 Series LoRa Transceiver Module (SX1262 based) and a small demo that shows two modules can talk. Everything must be written in C, build without warnings inside STM32CubeIDE, and rely only on the standard HAL and LL libraries.
Here is our expectations:
• Source files that handle all SPI transactions, register definitions, IRQ lines, power-up sequencing, and the usual send/receive flow.
• A self-contained CubeIDE example that compiles out-of-the-box, sets the radio to a default frequency and spreading factor, then shows a payload exchanged between two boards (UART printout of RSSI and packet data is enough).
• A brief document covering pin mapping, configurable parameters, and the public API so we can fold the driver into the rest of the project.
If you have worked with LoRa or other RF front-ends on STM32 before, this should be straightforward. We simply want solid, readable code that demonstrates stable communication, this will be probably the first project for a series of similar consecutive ones in coming weeks/months..
