The chip enters the serial bootloader when GPIO0 pin is held low on reset, as well as GPIO2 being left unconnected (floating) or being pulled down to GND. The esptool.py connects the EN pin of the ESP32 to RTS and the GPIO0 pin to DTR automatically to enter the serial bootloader, unlike other…

Bike embedded app: common questions

What microcontroller does the Bike embedded app use?

The Bike embedded app is built around the ESP32-WROVER-E, from the ESP32 family.

How big is the Bike embedded app PCB?

The Bike embedded app measures 66.5 × 92 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bike embedded app?

82 components, from 42 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 Bike embedded app design files?

From the nicolaeandreivasile/bike-embedded-app 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 Bike embedded app design in my own project?

The repository has no license, so all rights stay with nicolaeandreivasile. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Bike embedded app 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.
