The TPS61023 Boost Converter is the small step-up regulator I use in my low-power LoRa water tank sensor to generate a 5V rail from a single-cell Li-ion battery.
In that build the converter only runs while I take a tank reading. The ESP32 controls its enable pin, the TPS61023 powers the 5V pressure sensor for a few seconds, and then the boost stage is switched off again before deep sleep.
Check the listing carefully before buying. AliExpress results can include the bare TPS61023 IC, tiny breakout boards and different boost-converter modules under similar names. For this project you want a usable module with an enable connection and a 5V output configuration that suits your wiring.
What to check before buying
There are several boards sold around the TPS61023 name, so check the actual module rather than buying from the title alone.
- Make sure you are buying a complete boost-converter module rather than only the TPS61023 IC.
- Confirm the module can be configured or supplied for the 5V output your project needs.
- Choose a version that exposes the enable pin if you want the ESP32 to switch the boost stage off between readings.
- Check the board dimensions and pin layout against your PCB or enclosure before ordering.
In my tank sensor the enable pin is important because there is no reason to leave the 5V pressure-sensor rail running throughout the 30-minute sleep interval.
