About the Calsol hw libs PCB

Calsol hw libs is an open source ESP32 PCB design by CalSol, published on GitHub under the BSD-3-Clause license. It is a 2-layer board measuring 95.3 × 58.1 mm, with 45 components from 28 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the TPD4S012DRYR, LTC4151xMS, TCAN332 and CP2102N-Axx-xQFN24. By type, the board carries 13 resistors, 9 capacitors, 8 diodes, 6 ICs, 4 connectors and 2 transistors.

Calsol hw libs: common questions

What microcontroller does the Calsol hw libs use?

The Calsol hw libs is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Calsol hw libs PCB?

The Calsol hw libs measures 95.3 × 58.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Calsol hw libs?

45 components, from 28 distinct parts. The full bill of materials is listed on this page.

Where can I download the Calsol hw libs design files?

From the CalSol/calsol-hw-libs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Calsol hw libs design in my own project?

Yes, under the terms of its BSD-3-Clause license, which CalSol chose for the repository.

Can I test firmware for the Calsol hw libs 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.
