Final project circ 1: common questions
What microcontroller does the Final project circ 1 use?
The Final project circ 1 is built around the ESP32-WROOM-32D, from the ESP32 family.
How big is the Final project circ 1 PCB?
The Final project circ 1 measures 100.5 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Final project circ 1?
90 components, from 51 distinct parts. The full bill of materials is listed on this page.
Where can I download the Final project circ 1 design files?
