Single radio: common questions
What microcontroller does the Single radio use?
The Single radio is built around the BMP388, from the ESP8266 family.
How big is the Single radio PCB?
The Single radio measures 37.7 × 37.7 mm, has 4 copper layers and is 4.69 mm thick.
How many components are on the Single radio?
43 components, from 37 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 Single radio design files?
From the LongDo1902/STM32_Drone repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Single radio design in my own project?
The repository has no license, so all rights stay with LongDo1902. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Single radio without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
