Nano LoRa: common questions

What microcontroller does the Nano LoRa use?

The Nano LoRa is built around the RP2350B-QFN80, from the RP2040/RP2350 family.

How big is the Nano LoRa PCB?

The Nano LoRa measures 21 × 51 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Nano LoRa?

65 components, from 39 distinct parts. The full bill of materials is listed on this page.

Where can I download the Nano LoRa design files?

From the AayanShaikh007/Nano_LoRa repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Nano LoRa design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Nano LoRa without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
