Jalrakshak: common questions

What microcontroller does the Jalrakshak use?

The Jalrakshak is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Jalrakshak PCB?

The Jalrakshak measures 56 × 54 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Jalrakshak?

5 components, from 5 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 Jalrakshak design files?

From the rawrrudy/jalrakshak repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Jalrakshak design in my own project?

Yes, under the terms of its MIT license, which rawrrudy chose for the repository.

Can I test firmware for the Jalrakshak 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.
