About the TankSync tx PCB

TankSync tx is an open source ESP32 PCB design by gargsrishtii, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 100 × 100 mm, with 38 components from 23 distinct parts.

Its main chip is the ESP32-C3_SUPERMINI_TH, from the ESP32 family. Other key parts include the RYLR998, CN3791, MT3608, INA219 and AJ-SR04M. By type, the board carries 12 capacitors, 11 resistors, 6 ICs, 3 transistors, 2 connectors and 2 diodes.

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

From the project

Solar-powered transmitter PCB for TankSync wireless tank monitoring system — ESP32-C3 + LoRa + ultrasonic sensor, KiCad 10.0

TankSync TX is the transmitter-side PCB of a LoRa-based wireless tank level monitoring system. It measures tank water level using an ultrasonic sensor, monitors battery/solar power via a current sensor, and transmits data wirelessly over 868/915 MHz LoRa to the RX board.

Key features: - ESP32-C3 SuperMini as the main controller (compact, Wi-Fi + BLE) - RYLR998 LoRa UART module for long-range wireless communication - AJ-SR04M waterproof ultrasonic sensor for tank level measurement - CN3791 MPPT solar charging module for solar panel input - MT3608 DC-DC boost converter for regulated power…

TankSync tx: common questions

What microcontroller does the TankSync tx use?

The TankSync tx is built around the ESP32-C3_SUPERMINI_TH, from the ESP32 family.

How big is the TankSync tx PCB?

The TankSync tx measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TankSync tx?

38 components, from 23 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 TankSync tx design files?

From the gargsrishtii/TankSync-tx 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 TankSync tx design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which gargsrishtii chose for the repository.

Can I test firmware for the TankSync tx 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.
