WROOM32 Compute
About the WROOM32 Compute PCB
WROOM32 Compute is an open source ESP32 PCB design by Manuvr, published on GitHub. It is a 4-layer board measuring 24.8 × 31.7 mm, with 15 components from 12 distinct parts.
Its main chip is the ESP32-WROOM_U, from the ESP32 family. Other key parts include the FT231XS and ASTMLP. By type, the board carries 5 capacitors, 3 ICs and 1 connector.
From the project
KiCAD source files for Manuvr's motion capture glove.
This is one possible compute PCB to be used with Digitabulum-r2.
This PCB, combined with a backplane, and a Digitabulum-r2 board (plus sensors) forms a complete electronics package for a single motion-capture glove.
* Integrated USBSerial converter with Espressif monitor reset support.

WROOM32 Compute: common questions
What microcontroller does the WROOM32 Compute use?
The WROOM32 Compute is built around the ESP32-WROOM_U, from the ESP32 family.
How big is the WROOM32 Compute PCB?
The WROOM32 Compute measures 24.8 × 31.7 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the WROOM32 Compute?
15 components, from 12 distinct parts. The full bill of materials is listed on this page.
Where can I download the WROOM32 Compute design files?
From the Manuvr/Digitabulum-Hardware repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the WROOM32 Compute design in my own project?
The repository has no license, so all rights stay with Manuvr. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the WROOM32 Compute 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.
