Bluetooth module for WaterRowers

[^1]: The LM3525M must be soldered to the SOIC-8 TO DIP first [^2]: This part is EOL at Digi-Key. I do not know if there is a compatible replacement.

WaterRowerLinkPlus: common questions

What microcontroller does the WaterRowerLinkPlus use?

The WaterRowerLinkPlus is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the WaterRowerLinkPlus PCB?

The WaterRowerLinkPlus measures 55 × 95 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the WaterRowerLinkPlus?

47 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the WaterRowerLinkPlus design files?

From the nickbits1024/WaterRowerLinkPlus repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the WaterRowerLinkPlus design in my own project?

Yes, under the terms of its MIT license, which nickbits1024 chose for the repository.

Can I test firmware for the WaterRowerLinkPlus 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.
