Overview
5 V 1 A from a single LiPo cell
The ET-P05 is built around the TI TPS61023: synchronous boost, 3.7A switch, VREF 0.595V, true output disconnect in shutdown (0.1µA).
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- 5 V from a LiPo for NeoPixels
- USB power from batteries
- Servos and 5 V sensors on battery
