ESP32-ATT-C-LVGL8: common questions

What microcontroller does the ESP32-ATT-C-LVGL8 use?

The ESP32-ATT-C-LVGL8 is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the ESP32-ATT-C-LVGL8 PCB?

The ESP32-ATT-C-LVGL8 measures 80 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-ATT-C-LVGL8?

45 components, from 16 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 ESP32-ATT-C-LVGL8 design files?

From the oe5rnl/ESP32-ATT-C-LVGL8 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the ESP32-ATT-C-LVGL8 design in my own project?

Yes, under the terms of its MIT license, which oe5rnl chose for the repository.

Can I test firmware for the ESP32-ATT-C-LVGL8 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
