About the NIVA-pod PCB

NIVA-pod is an open source ESP32 PCB design by https-shubhamsahu, published on GitHub. It is a 4-layer board measuring 34 × 48 mm, with 62 components from 32 distinct parts.

Its main chip is the ESP32-C3-MINI-1-N4, from the ESP32 family. Other key parts include the MCP3208-CI/SL, LSM6DSO32TR, MCP6001T-I/OT, TLV75533PDBVR and MAX17048G+T10. By type, the board carries 28 resistors, 22 capacitors, 6 ICs, 3 diodes, 2 connectors and 1 switch.

It belongs with the iot & wireless designs in this gallery.

From the project

NIVA-pod: common questions

What microcontroller does the NIVA-pod use?

The NIVA-pod is built around the ESP32-C3-MINI-1-N4, from the ESP32 family.

How big is the NIVA-pod PCB?

The NIVA-pod measures 34 × 48 mm, has 4 copper layers and is 1 mm thick.

How many components are on the NIVA-pod?

62 components, from 32 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 NIVA-pod design files?

From the https-shubhamsahu/niva 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 NIVA-pod design in my own project?

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

Can I test firmware for the NIVA-pod 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.
