BL706 UNO: common questions
What microcontroller does the BL706 UNO use?
The BL706 UNO is built around the bl706_module, from the RISC-V family.
How big is the BL706 UNO PCB?
The BL706 UNO measures 68.6 × 53.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the BL706 UNO?
36 components, from 20 distinct parts. The full bill of materials is listed on this page.
Where can I download the BL706 UNO design files?
From the strongwong/BL706_UNO repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the BL706 UNO design in my own project?
Yes, under the terms of its Apache-2.0 license, which strongwong chose for the repository.
Can I test firmware for the BL706 UNO without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
