LoRaDongle: common questions
What microcontroller does the LoRaDongle use?
The LoRaDongle is built around the ICE40UP5K-SG48ITR50, from the FPGA family.
How big is the LoRaDongle PCB?
The LoRaDongle measures 95 × 67 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the LoRaDongle?
125 components, from 63 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the LoRaDongle design files?
From the marrrk/LoRaDongle repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the LoRaDongle design in my own project?
The repository has no license, so all rights stay with marrrk. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the LoRaDongle without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug FPGA firmware against it before you order a PCB.
