About the WellD PCB

WellD is an open source ESP32 PCB design by kinggh0stee, published on GitHub under the MIT license. It is a 2-layer board measuring 100 × 55 mm, with 99 components from 55 distinct parts.

Its main chip is the ESP32-C6-MINI-1U-H4, from the ESP32 family. Other key parts include the AP63205WU, CN3722, MT3608B, ADS1115IDGST and USBLC6-2SC6. By type, the board carries 31 capacitors, 31 resistors, 12 diodes, 11 connectors, 7 ICs and 3 inductors.

It belongs with the iot & wireless, power & battery and sensors designs in this gallery.

From the project

ESP32-C6 Zigbee well monitor — reads a 4–20 mA pressure transducer and DS18B20, reports water level, temperature, and battery to Zigbee2MQTT with OTA update support

Battery-powered well-level monitor for the ESP32-C6. Each wakeup it reads a 4–20 mA submersible pressure transducer, a DS18B20 temperature probe, and battery voltage; reports them over Zigbee to Zigbee2MQTT; then deep-sleeps until the next cycle.

- Radio: Zigbee 3.0 over the C6's built-in 802.15.4 — no extra modules - Battery life: months on a single 18650 cell at the default 5-minute interval (deep sleep between readings) - Adaptive sleep: sleep duration scales with how fast the level is changing — longer windows when stable, shorter during transients - Rate-of-change reporting…

WellD: common questions

What microcontroller does the WellD use?

The WellD is built around the ESP32-C6-MINI-1U-H4, from the ESP32 family.

How big is the WellD PCB?

The WellD measures 100 × 55 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the WellD?

99 components, from 55 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 WellD design files?

From the kinggh0stee/WellD 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 WellD design in my own project?

Yes, under the terms of its MIT license, which kinggh0stee chose for the repository.

Can I test firmware for the WellD 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.
