Rodi: common questions
What microcontroller does the Rodi use?
The Rodi is built around the ESP8266-07, from the ESP8266 family.
How big is the Rodi PCB?
The Rodi measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Rodi?
48 components, from 31 distinct parts. The full bill of materials is listed on this page.
Where can I download the Rodi design files?
From the rodibot/rodi-pcb repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Rodi design in my own project?
The repository has no license, so all rights stay with rodibot. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Rodi 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.
