About the SBRLOL PCB

SBRLOL is an open source ESP32 PCB design by hughminhphan, published on GitHub. It is a 2-layer board measuring 88 × 64 mm, with 21 components from 13 distinct parts.

Its main chip is the ESP32-DEVKITC, from the ESP32 family. Other key parts include the A4988_STEPPER_MOTOR_DRIVER_CARRIER, uA7805 and Adafruit IMU BNO055. By type, the board carries 6 connectors, 5 ICs, 5 capacitors, 3 resistors and 2 diodes.

SBRLOL: common questions

What microcontroller does the SBRLOL use?

The SBRLOL is built around the ESP32-DEVKITC, from the ESP32 family.

How big is the SBRLOL PCB?

The SBRLOL measures 88 × 64 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SBRLOL?

21 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the SBRLOL design files?

From the hughminhphan/PROJECTS repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the SBRLOL design in my own project?

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

Can I test firmware for the SBRLOL 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.
