About the ERS PCB

ERS is an open source ESP32 PCB design by t-robop, published on GitHub. It is a 2-layer board measuring 63.5 × 69.9 mm, with 15 components from 13 distinct parts.

Its main chip is the ESP32-DEVKITC-32D, from the ESP32 family. Other key parts include the TA48033S, DRV8835-akizuki, HC-SR04 and AE-XCL102D503CR-G. By type, the board carries 5 ICs, 5 capacitors, 2 modules, 1 battery holder and 1 switch.

ERS: common questions

What microcontroller does the ERS use?

The ERS is built around the ESP32-DEVKITC-32D, from the ESP32 family.

How big is the ERS PCB?

The ERS measures 63.5 × 69.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ERS?

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

Where can I download the ERS design files?

From the t-robop/ERS-PCB repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ERS design in my own project?

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

Can I test firmware for the ERS 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.
