The DevKit-Lipo series folds a LiPo charge controller onto an ESP32 board — WROVER-E for memory-hungry builds, S3 for native USB and dual-core AI workloads. Plug in a cell, plug in USB, done.
Same onboard LiPo charger, same in-house build in Pune. Pick the one that matches your I/O.
Hardware reset without unplugging power.
Program and power over a single cable.
Charge a connected battery directly from USB power.
Standard JST connector for 3.7V single-cell LiPo packs.
Onboard circuits report battery voltage and detect external power.
Every usable GPIO broken out, ready for jumper wires.

A typical ESP32 devkit needs a separate LiPo charger board bolted on beside it. DevKit-Lipo folds that circuit onto the board itself.
| Feature | Generic ESP32-DevKitC | DevKit-Lipo series |
|---|---|---|
| Onboard LiPo charger | Requires add-on shield | Built in |
| Battery + power sense | Not available | Onboard voltage & source sensing |
| Board footprint | Full-size + shield stacked on top | 48 × 28mm, single board |
| Extra wiring for battery use | Shield + jumpers | J2/J3 is the only thing you wire |
| GPIO breakout | Full 30-pin header | Full dual-row header |
| USB programming | Yes | Yes |
| Reset / boot buttons | Yes | Yes |
| Operating temperature | 0°C to +70°C (typical) | -40°C to +85°C |

Both boards are assembled on our own PCBA/SMT line — the same equipment we run for contract manufacturing work for other hardware teams. We handle placement, reflow, and inspection in-house, so the boards that ship are the ones we've actually tested.
