RicardoTemplate: common questions
What microcontroller does the RicardoTemplate use?
The RicardoTemplate is built around the ESP32-S3, from the ESP32 family.
How big is the RicardoTemplate PCB?
The RicardoTemplate measures 127 × 36.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the RicardoTemplate?
65 components, from 48 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 RicardoTemplate design files?
From the icl-rocketry/Ricardo-JollyRoger repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the RicardoTemplate design in my own project?
The repository has no license, so all rights stay with icl-rocketry. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the RicardoTemplate without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
